Federer even apparently even said "I'm really happy for you"
What an asshole.
typical wording from federer
makes it appear that he wishes good will and genial compliments....
what he is really saying is: 'i don't mind that you won tonight, cos i beat you the previous 6 times. i'm still the boss, you're still the bitch, and don't you forget it'
it is to del potro's credit that he didn't take the bait. he is a genuinely sporting guy, pity the rest of the top 10 generally aren't
