Mats Wilander comments in Tennis Week on Roger and Rafa:
Nadal is a very talented player, but I am not sure I think Nadal will have a good chance (to challenge Federer for No. 1) because the more he plays Roger, the more Federer's gonna learn how to play him and I guess that is Federer's strength: he adjusts so well to opponents and figures out how he has to play each opponent. I think where Federer differs is he is so talented physically, he can always work on his game and always improve stuff within his game. Federer can definitely improve his volley and he can definitely improve his serve. When you watch him, his serve and backhand are not always on all the time and I personally think he can improve his serve and backhand. Imagine if he even starts hitting his serve 10 mph harder how he will be even tougher to break than he already is now. Federer is one of those phenomenons and the question is how long can keep his mind into it to continue at this level? Will he get distracted or bored? I do hope guys will focus on beating him because it will be good for him and good for tennis. I personally don't like that he plays these smaller tournaments. Yes, it's great for those smaller cities that the world No. 1 comes to play, but I hope he doesn't burn out playing these smaller places.
Hmm....well I don't see Roger getting bored any time soon. And I think the other players ARE focused on trying to beat him it's just most of them aren't able to do it. Maybe they're getting bored of trying so hard to beat him only to come up short most of the time.
I don't want Roger to burn out either, but I like the fact he plays smaller tournaments. Of course money is a big part of it, but it also shows that he's not some snob who will only play certain tournaments or not try as hard in smaller events because they're not important enough. EVery tournament he participates in he plays to win.
