will federer gain his 1st rank back from nadal

now the question is if he can reamin world no 1 for longest time in history of tennis, he is like 25-30 weeks away.

Federer has a chance to regain the no.1,but if he regains the no.1 rank he may not be able to retain it for a long time with nadal and murray breathing down his neck.

here is what i think feel free to bash my opinion. Federer wont gain the spot back and if he does not for long. There are many young players willing to rip it out. Murray, Del potro and many more. Nadal will retire in a year or two. For the way he plays his body cant do it anymore. Running from one side to the other and hitting the ball with a over use of his shoulder. He will beat nadal and probably agin teh position again but not for long.
