I'm sorry for those who think that Nadal will dominate tennis for long years like Federer did. He's health clock is ticking, moment of blow is coming.
Federer has some chances to win one, maybe two slams, but nothing more. There are lots of factors, independent of him.
Well, good luck trying to find another slam for Federer, and good luck praying for Rafa's tendonitis treatment suddenly failing him. If Rafa wins the Australian Open we are talking about 6 straight slam wins if he takes care of business at Roland Garros and Wimbledon too. Winning 6 straight would put Rafa in a class of his own. And we've seen what he can do at the US Open now. No limits.
