I haven't had a cramp since '99. That was my only time, in Davis Cup, when I was panicky. I was young. I'm very proud of that. Never pulled out. Never had cramps. Never lost very much because of fitness, especially later on in my career where I knew I've put in the hard work. I've done that. I've been very fortunate and clever as well to understand how I need to work, when I need to work. So I'm very happy to have stayed injury free for so long. I hope I can still maintain a few good years on the tour. I really hope so.

I'm shocked every time that I've reached so many finals or won against so many players or whatever record it is. It strikes me and makes me obviously very happy and very proud that I've been able to do it for so many years at the highest of levels.

I have to fit holidays around tournaments, particularly the grand slams, in Melbourne, Paris, London and New York.

I have learnt to be even more patient.

When I won in 2003, never in my wildest dreams did I ever think I would win Wimbledon and have my kids seeing me lift the trophy, so this is pretty surreal. And yeah, I was almost shocked in the moment that it all came together so nicely.

My aim over the next few months is that I have a lot of points to defend in Miami and Hamburg, after that I can set my sights on No. 1.

I was aware of how incredible the match was. Unfortunately there had to be a winner. From my point of view many left feeling sorry for me instead of being happy for Rafa. Which hurts.
