Maybe you need to rewatch his matches this year to the likes of Fish, Ginepri or Ruben Ramirez Hidalgo. Then come back and tell me Fed is playing at the same level he has been playing in the last few years.
How short of memory you are. Fed has had his terrible matches all throughout his career, even when he managed to win in the end.
I never said he was playing on the same level, but as you seem to judge on RESULTS rather than on playing level, I thought I'd do exactly the same thing.
