Re: Your expectations for Federer in 2013.
yes 100% is not rational of course, but it's very likely that he will do worse than in 2012, yes.
I think people have not enough understood/realized how great his 2012 year has been. Many people compare with his best years, which is stupid : the guy is 31 years old, and when you look at tennis history, it's obvious that it's not anecdotical at all.
useless old guy
