Does the downfall have started for Federer ?

I dont think so.He will come back strong.He will come back with a vengence.He is still the best in business.

do you styill hold the same opinion ?

Depends on your point of view on the standard you expect from the top players, because Federer has ruled supreme for a long time, and now the game has moved on to the stage where he is no longer winning every match because there are other players who have raised the level of their games. The good thing about that is that we get the chance to enjoy a higher level of competition, without games having that inevitable outcome that used to happen a year ago. The mens game has moved on quite a lot, and we now have the situation that Nadal, Federer, and Djokovic, as the accepted top three, have all been beaten by the new up-and-coming form player, Andy Murray. The end of season shoot out should be a very interesting competition, with the top eight players going all out to show how much they have improved during 2008!

I think the same, but the quality of players is also increasing and since he has been playing for a long time, players in the ATP circuit have figured out his weaknesses. I think he still has one or probably two more grandslams left in him, I dont see him winning any more than this.
