Federer, Nadal smooth over talk of rift

Roger Federer says he has "no hard feelings" towards Rafael Nadal after criticism from his Spanish rival regarding an off-court issue.

Nadal said on the eve of the Australian Open that Federer was sitting back and allowing others to speak out and "burn themselves" seeking improved conditions for players.

Federer says "things are fine" between the two long-time rivals, although he concedes that they disagree on a way to resolve a list of player grievances which includes the length of the season and the distribution of prize money.

Nadal apologized Monday for airing his disagreement with Federer in public - although he didn't back down on the views he expressed.
