My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.

I don't know how you can go through a four-hour match with Rafa and he never gets a time violation.

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.

I feel a bit awkward playing in a red shirt out at Wimbledon. But I don't dislike it.

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.

Tennis can be a very frustrating sport. There is no way around the hard work. Embrace it. You have to put in the hours because there is always something you can improve. [Y]ou have to put in a lot of sacrifice and effort for sometimes little reward but you have to know that, if you put in the right effort, the reward will come.
