Andy [Murray] is one of the premier workaholics. He's given himself a lot of opportunities through that.

On how he met Wayne Gretzky: I was in L.A. preparing for Indian Wells, and a mutual friend asked if I'd like to have dinner with him. I think one of his daughters plays tennis so he knew about me. It was obviously something I was excited to do, and I left the dinner pretty amazed.

My goal is to keep him away from that and play the match on my terms so that I can be aggressive and not hesitate.
