You donknow anything about tennis. Vijay won volvo tournament once which is played by big stars. He has come upto semi finals in one of the slams againstt connors. He served match point but could not last. That is what I am talking about. Later I came to know it was asthma that prevented him from his achievement. Compared to that upto what round in singles Leander or Bhupati last. They get beated in the first round and so they gave up singles.
