All that swirls around Davydenko, it doesn't affect focus. PLaying bad affects focus. Chakvetadze gives up when she's playing bad.
But offcourt and personal crises, they don't affect focus. Most players block it out when they go on court.
Good win Kolya and people can hate him for the match fixing scandals and I'm not going to defend him but when he is trying he plays nice tennis and that's why I watch so still good to see in my opinion.
