These guys, especially Massu, Is capable of superhuman feats in terms of being able to be out on the court a ridiculous amount of time and coming back the next day and playing great tennis.

His backhand is much improved ... as well as his transition game and his volleys. He's getting to a point now where he's very comfortable up at the net. And now it's just getting the confidence to be able to do it in big matches.

In terms of running the team, I mean, it's pretty much the same as it always is. I've been, obviously, to quite a few ties with these guys and seen how Patrick runs the show. So it's pretty much status quo.

This decision, it was something that was hard for both of us, but we both realized that this was the best thing for Andy's tennis right now. There are certain coaches that are better in certain stages (of a player's career), so I think that as a player you have to figure out which coach is going to be best for you where you are at that moment.

Andy felt that basically I wasn't able to help him play his best tennis.

He really listened to what I had to say, and he was great, always treated me with respect.
