Every player left except for maybe Cilic. This is not the same Federer who is going to come out and outclass everyone, but rather grind it out, use his experience and patches of really good play.
after today's performance (and the one against Hewitt) i thought the mood will be exactly inverse - WOW Fed is back!
And it is the right one imo. Smashing the most inform player around in style was rather spectacular and i think no one could beat Roger right now.
Only obstacle could be Muzza but right now Roger is stronger, he's not making 50-50 in/out from BH and he's serving good, and, and..
When he is in such form, he is unbeatable in best of 5. That's what i think
