Re: What does federer need to work on before AO 2012 to maximize slam chance?
I remember how fit andre agassi was when he was 32,33 let alone playing 3 five settters in a row at the open when he was 35. I think federer can improve his endurance. He probably needs to mix up his training. I think he has that pierra pagnani guy but it would be good to spend time with someone else or at least switch it up some.
