AFTER surrendering his All England crown, Lee Chong Wei must be wary of Lin Dan's fiery form more than his shoulder injury in the run-up to the London Olympics.
It was disappointing to see Chong Wei conceding in the final but he has time and sports science support to help him recover from the injury.
However, it was the form of Lin Dan that is more imposing as he was far from the same player who looked subdued in Seoul just 10 weeks ago and lost to Chong Wei in the Korea Open.
It was evident Lin Dan has done his homework and has attained the physical condition needed to sustain top class performance and he can only get better.
The next battle between the two will probably be at the Thomas Cup Finals in Wuhan in May, and Chong Wei needs to get back to the drawing board to chart new strategies and to improve his physical condition.
Liew Daren gave his career and BAM a glimmer of hope with his improved performance in the All England and his quarter-final effort should be built upon with more good results.
The men's doubles final between the world's top two pairs - Cai Yun-Fu Haifeng of China and Jung Jae Sung-Lee Yong Dae of South Korea - was of the highest class.
The match was clearly a sneak preview of the Olympics final in London.
Both pairs played at an unbelievable speed and accuracy and it showed how far they have distanced themselves from their rivals, including Koo Kien Keat-Tan Boon Heong.
The Malaysian duo have to improve by leaps and bounds and there is still no certainty they can outdo the top two pairs, and their recent records against them are hardly inspiring.
Mixed doubles Chan Peng Soon-Goh Liu Ying can achieve more but they need to shed their inconsistency.
Peng Soon-Liu Ying, semi-finalists in Birmingham, had lost to Chong Wei and Vivian Hoo in the Selangor Open, and in the first round of the German Open a week before the All England.
This has affected their progress as they find it slow to move up the world rankings.
