If Andy really wants to overtake Federer in the rankings and indeed prevent anyone else overtaking him I suggest he enters more tournaments, cuts the everlasting "training" and gets a bit of match practice
I wouldn't disagree with that. Andy seems to think that total physical fitness will help him win Slams, but, as Federer once said, there's a difference between being gym fit and match fit.
Obviously being as fit as possible is crucial but it came out the other day that Andy spends more time in Miami doing extremely rigorous fitness training with various sporting groups than he does practising tennis. Also other players take regular holidays. Andy doesn't.
And ends up completely knackered by the time the majors come round. Yep, makes sense that.
Yes but he frequently ends up being knackered, or ill or injured, anyway for the reasons stated above. Doing what he's doing is probably adding as much stress to his body as playing two or three extra tournaments, so it's counter-productive really.
