I saw Nalbandian play a few matches at Cincinnati in 2003 and he didn't seem to be enjoying himself though I was impressed with his game (he made it to the QFs). After one of his wins I stood outside the gate to try to get an autograph (there were about a dozen of us waiting), he came up from the court looking completely disgusted and grimacing and he only signed for the first 3 people. Made me wonder what this guy is like after he loses, if that was his behavior after winning
Also, his disagreement with the officials at TMC 2003 (as highlighted by Tennis Masters Cup Uncovered, shown on TTC) didn't help my opinion of his attitude towards tennis.
Then last year I saw him practicing at Cincinnati 2004, looking pretty good I thought so I was dumbfounded when the next day he'd withdrawn with an injury. Even more puzzling, one of the volunteers for player transportation told me she took David to the airport and he was "all smiles and happy as a clam". I know this may sound absurd, but did someone force him to play tennis?
Is it possible that his inconsistent tennis is due to his mentality, and not because of injury and personal issues? He's got the talent to get back to the top but I don't see it happening this year.
