Credit to Chen Long and his coaching staff deploying very patience strategy knowing Chong Wei is prone to unforce error for long rally, can CW overcome this mistake? I think is a bit too late for this event. Sometime it's not playing fast and furious are better, CW should slow down the pace to cut down the unforce error.
Dont tell that this error of this youtube will last till the end of this match! I've been looking forward to the XD match!
