Roger and Novak are obviously not the best friends off the court, but from what Roger said yesterday in his post match interview they do respect each other:
"Q. What is the personal relationship like given a few years ago you made some forceful comments about him from Davis Cup?
ROGER FEDERER: No. I thought that was more brought up by you guys. Not that you guys are to blame, but you guys like to put something between the top players.
I was just upset at him calling the trainer out for no obvious reason against my buddy, Stan, in a five‑setter. That was it. We had a quick chat about it in Madrid after that, and things are cool since a long time between me and him. I've always respected him. Have I gone out for dinner with him? No.
But had many meetings with him at the council, and then now with the Grand Slams. He's been nice to work with. You know, we've met on several occasions because of other things together.
Yeah, I have no issues with him, and I hope you believe me."

Regarding what Rusedski generally says, I believe he is a real pain. I can't listen to him for more than 2 minutes before I mute the TV....
