Yeah!!! He was smiling and of course, so many good memories were coming back into his mind! He went back there on purpose, to feel the glory of all his biggest achievement so far, just before Houston.
Let's hope he will keep this in his mind until the tough matches he'll have to play there. All will depend on what will be in his mind at that time. It's all in the head! He can do some great performance, he just has to believe in himself. It's not his suitable ground, everybody agrees with that. But don't try to pretend he has never won any match indoors and on that kind of surface! I tell you, it's all in his head.
