What i mean by that is he'll start beating the top guys. Changing game means if you observe carefully federer is still trying to play like he did in 05/06. He is still trying to hit the winners like he did back then and that is what's causing these huge error counts. He's not the same player as he was in 05/06 according to everyone he's "LOST HALF A STEP". He is getting to the balls a split second later than in 05/06 and still trying to hit the same winners. It's simply not gona work according to the the LAWS OF PHYSICS. So what he's gota do is hit 3/4/5 more shots get into that same position by defence and moving the opponent around and then crack the winner. He's simply just gota keep the rallies a few shots longer in order to make up them split seconds that he's lost since 05/06. Main reason federer has had a problem against nadal from the outset is when he plays other guys he can dominate from baseline, he stands right on the line and dominates and hits winners. When he plays nadal he's almost 2-3 meters behind baseline and STILL trying to hit the same type of winners which lead to his HUGE ERROR COUNT against nadal. It's got more to do with that than his backhand falling apart. His backhand held up fine in wimbledon 08 and aussi open 09, yet people keep saying he's gota change his backhand naaaaaaa HE'S JUST GOTA ADAPT TO HIS NEW GAME!!!!!!!!! MAN I SHOULD BE A COACH!!!!!!!!!!!
