When I think of the Olympics I only think of good things. I think of what a great event it is and what it has done for me and my career, and changed my personal life, too.

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.

Being down match point, it's just not fun.

Being a husband is for me as big a priority as being a father.

Once you reach a good level in tennis it fills you with a lot of motivation. I hope I can do it for a long time.

But so far I have the feeling that the chances are there to repeat last year's season.

I have a very strong opinion. I'm absolutely against it. I'm against the challenge system. I'm for the way it is right now. Don't change that.
