This match could go either way. I mean Federer never plays badly, he sometimes meets a superior in Andy, Novak and Rafa. He can beat anyone else on any given day.
It'll all be down to Andy, if he can play his VERY best, aggressive tennis. Fedface is almost as fresh as a daisy, like Andy. Good thing Jo-Wilfried made him sweat for 5 sets, but he'll be well recovered by Friday.
I am off on Friday, so I can watch it
