So Berdych was much tougher opponent I guess? With Simon humiliating him in comfortable 3 sets? That's bs, Simon in his form will trouble Fed much more, he can make a 5 setter from it, but I doubt it. Fed in 4.
Here comes first real challenge for Roger. Have a feeling that Gilles would take it.
Roger needs to protect his own service games carefully. Gilles serves so well so far I don't think he could put pressure on return games like previous meetings. And he should hit pace with variety otherwise Gilles could counter punch him to death.
Simon has been playing well, and he managed to get past Berdych in 3 easy sets so should be fresh enough for this match.
Federer has been basically untroubled so far, but he has had an incredibly easy draw to the QF and he is prone to looking great dispatching mugs in early rounds then flopping hard as soon as he reaches his first dangerous opponent. On paper this one will be much tougher, and if Simon plays near his best level Federer should certainly have a tougher time than his early matches, but I think he will get through in 4 sets.
