Personally, I think he still need sometime to recover fully, think he is very cautious about his feet. But good to see him back in action.
hmmmmm am not quite sure, last time i saw him was when he was playing with H.K againt india but boy was he good, well atleast i thought he was anyway
he was placed in the doubles as it is less strenuous than playing singles and would be better recovery for his leg.
