How can a player who is has less than half the number of points as Federer, and consistently lose against fed or any top 10 player in straight sets can be a threst to number 1 ranking. Be ralistic Nole..and why are you discounting your friend Andy Murray as a future number 1. Even Federer rececntly rated Murray better than you. If Federer's recent slump in form is due to monnucleosis as he says, then the passage to first place wont be that easy once he recovers and moves as freely as before. Remember Djokovic and Rafa is defending loads of points in North American masters, whereas Fed can gain further lead by just reaching semi or even quarter here.
