Chong Wei Lee

2002–2007

Lee picked up only one minor title during the 2002 and 2003 seasons. He reached his first final of a major tournament at the 2003 Malaysia Open where he was defeated by Chen Hong of China. Lee then secured two titles in 2004, the Malaysia Open and the Chinese Taipei Open. Lee gained a spot for the 2004 Olympic Games in Athens. In his first Olympic appearance, Lee defeated Ng Wei of Hong Kong in the first round. His journey ended in the second round when he was defeated by Chen Hong. Lee scored another two titles in 2005, his second Malaysia Open title and the Denmark Open. Lee won a bronze in his first appearance in the world meet, the 2005 World Championships after losing to eventual winner Taufik Hidayat in the semi-final.

Lee won three titles out of six finals in 2006. He was crowned as the winner of the Swiss Open, Asian Badminton Championships and his third Malaysia Open title. He also reached the final of the Chinese Taipei Open, Macau Open and Hong Kong Open. In the Malaysia Open, Lee fought back from 13–20 down in the rubber match and saved eight match points against Lin Dan, and finally won the game with a score of 23–21 to secure the title. Lee won Malaysia's two gold medals in the badminton event for 2006 Commonwealth Games, in both the men's singles and mixed team events. Lee reached the top spot twice in the Badminton World Federation's world rankings in 2006, and he participated in the World Championships as top seed. However, he was upset by Bao Chunlai of China in the quarter-final despite Lee winning at their previous meeting. The match was also marred by two controversial line calls that were not in favour of Lee.

During the 2007 season, Lee failed to reach the final of the Malaysia Open for the first time in five years. He also suffered an early exit in five competitions afterward. Later on that season he took the Indonesia Open crown, his first title since the 2006 Malaysia Open after reuniting with former coach Misbun Sidek from Li Mao. His performance at the second half of the year was solid, as he achieved three titles in the Philippines Open, the Japan Open, and the French Open. He also managed to reach the final of the China Open and Hong Kong Open, despite his knee injury haunting him on both occasions. Lee won all matches he played in the Sudirman Cup in June, despite Malaysia finishing just fifth in the tournament. Lee's low point of the year was in the World Championships, despite the tournament being held in front of his home crowd and his solid performance during the second half of the year, he was defeated in the third round by Indonesia's Sony Dwi Kuncoro. Lee criticised the chief coach, Yap Kim Hock for treating him indifferently and putting pressure on him before the world championships. While the chief of Badminton Association of Malaysia, Datuk Nadzmi Mohd Salleh encouraged Lee and the chief coach, Yap Kim Hock to improve their relationship.

2008

Lee kicked off 2008 with success, capturing his fourth Malaysia Open title in five years. However, Lee only captured one more other title that year, the Singapore Open, which was the final tournament in his pre-Olympic preparations. Other tournaments he took part in were the Korea Open; the All England Open; the Swiss Open; the Badminton Asia Championships; and Thomas Cup in Jakarta, Indonesia where Lee helped Malaysia advance to the semi-final. In the semi-final he defeated Lin Dan to give Malaysia a 1–0 lead in its clash with defending champion China, but Malaysia eventually lost 2–3 due to the defeat of its first doubles team in the vital final match.

In the 2008 Olympic Games, Lee was given a bye in the first round. He cruised to straight game victories over Ronald Susilo in the second round, Kęstutis Navickas in the third round, and Sony Dwi Kuncoro in the quarter-finals. In the semi-finals Lee Hyun-il gave him a tough fight, but eventually Lee was able to beat the South Korean and reach the final. However, it was a one-sided final, as Lee was completely outplayed by Lin Dan and salvaged only 20 points, losing 12–21, 8–21. He came second place overall.

Lee participated in several tournaments after the Olympic Games without capturing a title. He advanced to the finals of the Japan Open, the Macau Open and the China Open, but lost to Sony Dwi Kuncoro, Taufik Hidayat, and Lin Dan respectively. In the French Open Lee was eliminated in the semi-finals. His coach, Misbun Sidek, cited the pressure of being ranked world number one to explain Lee's recent failure to capture a title.

Lee ended his last Super Series tournament of the year, the Hong Kong Open, with a sudden withdrawal due to a knee injury, conceding a walkover to Germany's Marc Zwiebler. His last minute withdrawal led to the Chinese media tagging him as the "weakest world number one". The Chinese media speculated that three factors had hampered Lee's performance since the Olympic Games: the stress of the Olympic final, a phobia of Lin Dan due to his lopsided Olympic defeat at Lin's hands, and (echoing Misbun Sidek's conjecture) the pressure of being the world number one.

Despite Lee's difficulties in international play, he recorded his seventh consecutive victory at the National Badminton Grand Prix Final in Kedah on 12 December 2008, thus breaking the record of six consecutive titles set by Misbun Sidek. Lee ended the year with a title in the Super Series Masters Finals. However, Lin Dan and China's other top players did not compete, their association citing injuries and fatigue.

2009

Lee Chong Wei started the 2009 season with his fifth Malaysia Open title. He failed to secure his first Korea Open and All England Open title despite marching into the final. However, he secured his second title of the year in the Swiss Open which was held in Basel, defeating Lin Dan in straight sets and marking his first win in the finals against the Chinese opponent outside home turf.

Next, Lee was defeated by Chen Long of China in the India Open. Lee claimed he lost because of food poisoning and insisted that authorities improve the conditions before the World Championships. In May, Lee helped Malaysia reach the semi-finals of the Sudirman Cup, the first in national history, despite his unbeaten record in the tournament being blown out by Lin Dan. He won another two titles in June, the Indonesia Open and the Malaysia Open Grand Prix Gold, despite failing to defend his Singapore Open title when he was taken by Nguyễn Tiến Minh in the second round.

Lee kicked off the second half of the season with defeat by Sony Dwi Kuncoro in the world meets, but went on to win the Macau Open in August. He reached the semi-final in the China Masters, but once again failed to beat his all time rival Lin Dan. Then, Lee participated in the Japan Open. He only managed to reach the second round of the Open, before winning the Hong Kong Open in November. His inconsistency saw him tumble down in the first round of the China Open. In December, Lee defended his Super Series Masters Finals title, which saw the competition played without the top badminton players in the world.

2010

Lee started the year with the title in all events he took part, his first treble in the Super Series titles. He gained his first ever Korea Open crown, sixth Malaysia Open, and defeated Kenichi Tago to win the oldest and prestigious badminton championship in the world, the All England Open, his first since he took part in 2004.

Lee participated in the Thomas Cup in his home ground. He managed to defeat Kenichi Tago and take the first point, despite Malaysia's eventual loss (2–3) to Japan. In the quarter-finals, he beat Peter Gade, thus helping to secure Malaysia's place in the semi-finals. In the semi-finals against China, Lee was defeated by Lin Dan, which ended his 18-match unbeaten record since the start of the year.

In June, Lee participated in the Singapore Open losing in the quarter-finals. However, Lee bounced back winning the Indonesia Open, Malaysian Open Grand Prix Gold in July, and Macau Open in August. In late August, Lee suffered a shock exit in another attempt for the World Championships, but was beaten by Taufik Hidayat in the quarter-finals. Misbun cited that the loss was due to the back injury he picked up after the match against Rajiv Ouseph in the third round. On 26 September, Lee beat his archrival Lin Dan in the Japan Open, the only title not taken by Chinese players in the tournament.

In October, he helped Malaysia to beat India to defend the gold medal at the 2010 Commonwealth Games mixed team event, then he successfully defended his gold medal once again in the singles event a few days later. The following month he won a silver medal at the Asian Games. Despite beating reigning World Champion Chen Jin in the semi-final, Lee once again tasted defeat at the hands of his rival, Lin Dan, in the final. At season's end, he won his second consecutive Hong Kong Open title, and third consecutive Super Series Master Finals title, where the tournament was held in January 2011.

2011

In January, Lee won his seventh Malaysia Open title by defeating Taufik Hidayat from Indonesia in the final. However, he failed to defend the Korea Open title, the world's first ever million-dollar badminton tournament, after being beaten by Lin Dan from China in three games. In March, Lee cruised into the final of the All England Open for the third consecutive time and retained his title successfully with a convincing straight games victory over Lin Dan, and was praised by prime minister Najib Tun Razak.

On Labour Day, he won his first ever India Open, and also his third consecutive Malaysia Open Grand Prix Gold title a week later. Despite the fact that Lee won all the matches he played during the Sudirman Cup, Malaysia's journey ended in quarterfinals, after being beaten by South Korea 2–3. In late June, he won the Indonesia Open, becoming the first non-Indonesian player to complete the hat-trick in the tournament.

Lee's hopes of becoming the first Malaysian to win gold in the World Championships were dashed after defeat by Lin Dan in the final. Lee led for most of the match but lost two important match points in the rubber game. In September, Lee also failed to defend his Japan Open crown after losing to China's rising star Chen Long. In October, he lost to Chen Long again in his bid for his second Denmark Open title. He won the French Open a week later. This was followed by triple semi-finals exit in the Hong Kong Open, the China Open, and the Super Series Master Finals.

2012

Lee started the Olympic year with the first Super Series tournament of the season, the Korea Open. In a repeat of the previous year's final, he avenged his loss to Lin Dan by defeating him in three sets. A week later, he captured his fifth straight and eighth Malaysia Open title, thus equalling the number of home titles held by Wong Peng Soon who won them between 1940 and 1953.

In March, Lee lost in the All England Open when he bowed out in the second game after receiving medical help on three occasions. This also dashed Lee's hopes of becoming the first man to win three successive All England Open titles. In April, he was defeated by South Korean Shon Wan-ho in the final of the India Open, but retained his Malaysia Open Grand Prix Gold title for the fourth time in a row in May. Lee was out for three to four weeks after suffering an ankle injury during the Thomas Cup Group C tie against Denmark.

Lee returned to the court for the first time after recovering from his injury to play in the London Olympic Games. He closely beat Ville Lång of Finland in rubber games for the first round, and blamed pressure for the close defeat. In the second round, he eased to a victory against Indonesia's Simon Santoso, before beating Kashyap Parupalli of India in the quarter-finals. In the semi-finals, he beat Chen Long of China in straight sets despite early predictions that Chen would be difficult to beat, and set up a repeat of 2008's final against Lin Dan. This was the second meeting in the Wembley Arena for both players after the 2011 World Championships. Lee led the match after winning the first game but Lin brought it to the rubber games. Despite leading for most of the time in the third game, Lin managed to level the point and edge him narrowly by 21–19, forcing Lee to settle for silver once more. BBC Sport analyst Gail Emms said, "You couldn't have asked for any more from Lee Chong Wei." This epic episode was documented in an academic article entitled "Silver lining in winning silver: an exploratory study of supporters’ reactions and coping on the social media towards Lee Chong Wei's London Olympics defeat".

He won the Japan Open and Denmark Open on his return since the London Olympic Games, but lost in the final of the Hong Kong Open, only a few days after his marriage. Lee ended the year with a loss in the opening match of the Super Series Master Finals and subsequently pulled out of tournament due to a thigh injury.

2013

Lee took the Korea Open title for the third time. A week later, he captured his ninth Malaysia Open title, which broke the record of eight titles previously held by Wong Peng Soon. Lee then lost in the final of the All England Open to Chen Long. Lee said he was disappointed with his performance during the tournament, despite marching into the final.

In April, he lost in the semi-finals of the Australia Open to the young Chinese player Tian Houwei. He then won his second India Open title and fifth Indonesia Open. In August, Lee marched into the final of the World Championships, but his hopes were once again dashed in a repeat of his 2011 final and 2010 Asian Games defeats against Lin Dan. He suffered leg cramps late into the third game. After attempting to continue, he had to retire and was subsequently stretchered to hospital.

After the World Championships Lee participated in four Super Series tournaments. First, he took the Japan Open title for the fourth time. Then he lost in the final of the Denmark Open and semifinal of the French Open, and triumphed again in the Hong Kong Open.

Lee won a record fourth Masters Finals title, the season ending Super Series tournament.

2014

In January, Lee lost in the final of Korea Open to Chen Long, his fourth straight defeat by the Chinese. He recorded his tenth Malaysia Open title a week later. Soon after the triumph, he announced it would be his last Malaysia Open outing, as he would assess his condition after the Asian Games and might retire if the results were not good.

However, his form improved and he won his third All England Open and India Open titles, although he was beaten by Simon Santoso in final of the Singapore Open. In the Thomas Cup, Lee won every match he played. Malaysia reached the finals, but lost to Japan with a score of 3–2.

In June, he won the Japan Open for the third consecutive year and fifth time overall. He then lost in the semifinals of the Indonesia Open, ending his hopes of nine straight Super Series finals. Due to a serious hamstring injury, Lee withdrew from the 2014 Commonwealth Games in July, also ending his hopes of being the first men's singles shuttler to win 3 back-to-back gold medals at the games.

Lee resumed play in August where he finished second for the third time at the World Championships, losing to Chen Long of China in straight sets. He again lost to Chen in the semifinals of Asian Games team competition, and to Lin Dan in the semifinals of the singles event a few days later.

Doping

In October 2014, local media reported that the Badminton Association of Malaysia confirmed that one of the nation's top shuttlers tested positive for dexamethasone after urine samples were taken during the World Championships in late August. The identity of the shuttler was not revealed but was widely believed to be Lee Chong Wei. Dexamethasone is not a performance-enhancing drug but a commonly administered anti-inflammatory corticosteroid that is not illegal when used off-season for injury rehabilitation, but deemed illegal if discovered in an athlete's body during competition.

On 5 November 2014, Lee flew to Norway to witness the testing of his "B" sample at the Oslo University Hospital after the "A" sample had already tested positive in October. The results were announced on 8 November 2014 by a Malaysian sports official who confirmed that the "B" sample had tested positive as well. He declined to identify the player but confirmed to The Associated Press that it was Lee.

On 11 November 2014, the Badminton World Federation confirmed that Lee was temporarily suspended from competing due to an apparent anti-doping regulation violation. The hearing was held on 11 April 2015 in Amsterdam.

On 27 April 2015, it was announced that Lee had been handed a backdated eight-month ban for his anti-doping rule violation. The panel was convinced that Lee had no intent to cheat and allowed him to resume his career by 1 May 2015. Lee was stripped of his silver medal from the 2014 World Championships but allowed to keep his two bronze medals from the 2014 Asian Games.

2015

The Sudirman Cup was Lee's first tournament after serving an eight-month suspension for a doping violation. He went on to win all three matches he played in the tournament. He then took back to back titles by winning the US Open and Canada Open. Lee again had to settle for second place at the World Championships as he lost to Chen Long in the final.

After the World Championships, Lee endured three early-round exits. First, in the second round of the Japan Open, followed by the qualifying rounds of the Korea Open, and then in the second round of Denmark Open.

After three early-round losses, Lee bounced back to win the French Open, followed by his first ever China Open title, thus making him the first-ever men's singles shuttler to have won all Super Series titles. The following week, Lee won the Hong Kong Open. However Lee did not qualify for the Super Series Finals, ending the year with three back-to-back titles.

2016

In January, Lee won his fifth Malaysia Masters title. In March, Lee lost in the first round of All England Open, and also in the second round of the India Open. In April, Lee won his 11th Malaysia Open title, then followed by his second Badminton Asia Championships title. At the Thomas Cup in May, Malaysia lost to eventual winners Denmark in the semi-finals despite Lee winning all the matches he contested in the tournament. In June, Lee won his 6th and record-equaling Indonesia Open title, becoming the third shuttler and first non-Indonesian to win the title six times. He was set to play in the Australian Open, but withdrew due to a muscle injury.

On 5 August 2016, Lee led the Malaysia contingent during the opening ceremony of the Olympic Games. In the men's singles competition he made it to the final, defeating his longtime rival Lin Dan in the semifinals in a dominating performance. However, he was defeated by Chen Long in the final, his third successive defeat in the final of the Olympic Games.

In September, Lee won his sixth Japan Open title. Since then, Lee has failed to win any tournament he participated in: he was defeated in the third round of the Denmark Open, pulled out from the French Open due to a hamstring injury, and ended the year with a group stage exit in the Super Series Finals.

2017

He started 2017 season with his fourth win in All England Open. He nearly missed out on the tournament after tearing the medial collateral ligament during a training session at the new Academy Badminton Malaysia (ABM), this caused his feud with technical director Morten Frost, as Frost was not receptive to his complaint, asking for the slippery mats to be replaced. Lee lost to Lin Dan for two consecutive tournaments, the first in the final of Malaysia Open, and the second in semifinals of Badminton Asia Championships.

In May, Lee won all the matches he contested during the Sudirman Cup. A month after, he lost in the second round of Indonesia Open. In August, Lee was upset by Brice Leverdez in the first round of the World Championships, soon after, he apologises to Malaysians for his defeat in his Twitter account but received some touching reply from the fans.

He ended the year with lost in the final of Super Series Finals.

2018

Lee won his fifth Commonwealth Games gold medal in April, and settled for silver in the mixed team event.

He failed to win any World Tour titles in first half of the year. He bowed out in the first round of Malaysia Masters, a tournament which he claimed he did not intend to participate in, third round of All England Open, and semi-finals of Badminton Asia Championships.

In the team event, Lee managed to win all his matches, in both the Badminton Asia Team Championships and Thomas Cup. Malaysia reached the semi-finals and quarter-finals in the respective events.

In July 2018, Lee extended his own record at the Malaysia Open, taking a 12th title in his 14th final, and reached the semi-finals of the Indonesia Open. A week before the World Championships, the Badminton Association of Malaysia (BAM) announced that Lee would not be able to take part in the championships and also the Asian Games as he has to undergo treatment for a respiratory-related disorder. His participation in these two tournaments was in doubt even before the announcement after media reported that he was absent from the training. He was diagnosed with early stage of nasopharynx cancer and received treatment in Taiwan.
