I lost a little bit of confidence about me, ... I am not playing good this week...There are moments when you don`t have the confidence and this is one of those moments.
I don`t want to think about it because I always want to stay the same, ... I only want to think about next week. I`m happy I`ve won a grand slam, three Masters Series and five [other] tournaments, but I can`t think about that now. I`ll think about it at the end of the year.
To be honest, I haven`t felt at my best since this tournament began. I didn`t feel good with the court or the balls. But those are excuses. You have to accept when you don`t play well and somebody else does.
