I don't like him but I see nothing wrong whith saying stuff like that.All the big names of today (Fed, Rafa, Nole)grew up thinking the exact same thing or else they wouldn't be there.
They grow up thinking they hope someday to be number 1, but not even Federer thought he'd be in the running for best ever. You can tell by how he treasures that first Wimbledon - he knows how hard it was to finally win a grand slam after all the expectation.
I'm not a Nole fan, but he always gives credit and respect where it's due. Whatever he said could possibly be excused as English being his second language. Tomic has no excuse. He needs to heed the advice from Fed in his South American interview - in this day and age, there's a camera/video EVERYWHERE. One must be careful of what one says.
And as far as Safin is concerned, anyone who can thrash Sampras as he did as US Open Final and go toe-to-toe with Fed and beat him in his peak, can say what he wants. Too bad he didn't have the head to realize that talent to its full potential.
