Roddick can challenge him as well if he serves big consistently for the entire match. If he does that, then he is tough to break even for a guy like Federer.

It's very tough to break him because he has a very big lefty serve,

I'm a big boy, and I'm a tough guy.

Federer can be the best ever; he has the potential. The only question is whether he has the desire.

I was prepared for a tough match. In the second set, he started to serve much better. He started to come on and he had me under pressure.

Then he took me off Jeannie and he gave me Millie the Model. That was a big break for me. It wasn't doing to well and somehow when I got on it became quite successful.
