Paul Dorochenko worked with Roger Federer in the late 90s, when the Swiss player wasn't a top player yet. Dorochenko was privileged to know the current world No. 1 well enough as a fitness trainer, and it wasn't that easy to manage him mentally.
'The truth is that he was a very complicated kid, very active, half crazy', Dorochenko told La Razon. 'He was a good person, but a very complicated one: was losing racquets, was behaving badly and lost matches.' Federer always worked to have a long career.
'For me, he can play until he is 40 without any issue. He will stop when he starts losing to more normal people. He likes to win, like everyone, but he likes it more. Federer has this thing that the "tops" have: [Zinedine] Zidane, [Michael] Jordan...he moves in an impressive way.
His mother always said me that she didn't see him very smart, and he really never did very well at school but he loves tennis so much and he invented it'. 'I would have never thought that Federer would have been the player of the century, I could not see him winning in Paris, and he did it', Dorochenko admitted.
'I knew he could be a great player, that's for sure, but from here to win 20 Grand Slams... and I think he will win more. The good thing for me is that I made a little part of history, and not so many people worked with him.' ALSO READ: Roger Federer's fitness trainer fuels speculation about his clay season
