DAVID FERRER: I don't know. Now I want to be focus with my next match. Is very difficult for to win a Grand Slam because there are the top four. In this moment, the last three or four years, they are better than the other players.
But, you know, I am not thinking about if I have the chance to win a Grand Slam. I am only focus with every match I will play.
