There always seem to be problems and now it's obviously the rankings.It's great that Novak's done well the last few weeks but the first three or four months of the year I played a lot better than him so I think the rankings reflect very well how the guys are playing.Until this week I've never heard anyone complain. I think maybe only in the last week it's become a problem for Novak.I understand what Rafa's saying with the two year thing.It's kind of like in golf where there's not so much pressure every single week to play.
