We should be appreciative of Federer though, because we will never see anything like him again. The fact he can still compete for slams ever after the erosion of his physical skills is really a greater testament to the natural talent he has than the period of time when he was dominating the tour.
Maybe, but at the same time, he's not solid enough right now to beat top players consistently. He'll just be another guy who hangs around, like Malisse. He could be much better than that, but he needs to mature on court mentally and be smarter.
