Second most succesful ?
Nadal surging ahead is not a bad thing, i Remember Federer saying that tough competition is what made him still hungry and look for that little bit extra in trying to stay level, Andy & Novak will simply look for ways to improve their own games in order to match Rafa's level, both of them may have been complacent, but they will now have added incentive to improve.
Not sure how people can think Andy has had a poor year when he's the 2nd most succesful player on tour currently.
I'd been thinking on rather similar lines gnome. Andy has beaten Nole twice now in slam finals. He knows he can do it whereas he hasn't beaten Rafa in a slam final and so the challenge is that much bigger. And Andy thrives on challenges. It may be just me trying to find silver linings but I'd love to see Andy rise to that challenge next year (and also in WTF)
