Everyone has to call 'time' at some stage.
Matches are won and lost so many times in the locker room.
Maybe if you're playing in London or America, you don't feel that pressure quite as much.
I'm not a guy who needs to read motivation books.
When I go out to play, I still believe I'm as good as anyone out there. I don't have to prove anyone wrong. I know what I've done and how well I can play.
I think I was as mentally tough as I've ever been. I felt like I handled the situation both on and off the court extremely well. I felt like I needed to.
