BIRMINGHAM -  Malaysia's Lee Chong Wei was at his sublime best as he claimed the All England Open title for a third time with a 21-13 21-18 win over Chen Long on Sunday. After avenging his final loss to Chen last year, the 31-year-old world number one hinted that Sunday could be his last appearance at the tournament. "I think maybe this is my last All England," Lee told reporters."I'm very happy and I tried my best because Chen Long is a very tough match for me. I've lost to him (Chen) many times so I think for this reason I made sure I tried very hard. I've finished for this year and I don't know if I will be back next year." While Chen went home empty-handed, there was joy for his girlfriend Wang Shixian after she beat top seed and Olympic champion Li Xuerui 21-19 21-18 to capture the women's title.Wang showed patience and ruthless efficiency. "There are still a lot of big tournaments waiting for me to win so hopefully I can keep going," said Wang. Yu Yang and Wang Xiaoli showed they had come a long way since being expelled from the 2012 London Olympics for throwing matches as they saved a match point before beating Ma Jin and Tang Yuanting 21-17 18-21 23-21 in the all-Chinese women's doubles final to retain their crown.There was success for Indonesian pair Mohammad Ahsan and Hendra Setiawan who defeated Japan's Hiroyuki Endo and Kenichi Hayakawa 21-19 21-19 in the men's doubles final. Tontowi Ahmad and Liliyana Natsir then fended off Chinese top seeds Zhang Nan and Zhao Yunlei 21-13 21-17 in the mixed doubles final to secure an Indonesian double.
