You know, I don't only play for the record books.

I never expected i, in the first place, when I started playing tennis, that I would ever carry the flag into the Olympic Stadium for an Olympic Games... So for me that was a surprise and a huge honor in my life to be able to represent Switzerland.

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.

Clearly, when you win everything, it's fun. That doesn't necessarily mean you love the game more.

I can walk around screaming, 'I have 17 Grand Slams. I have the record here or there.' When you can play for history and you do it, that's what is so really cool, is that you can then be compared to other greats or you've passed another great, even though it doesn't mean you're better than him. But it's just like that moment you've gone into the unknown where nobody else has ever been before.

Sometimes you have to accept that a guy played better on the day than you.

You can't expect yourself to be already peaking like crazy in an exhibition tournament.
