I love tennis! I've always felt like this because it is such a classy sport with a great, competitive flair to it.

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.

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.

Sometimes I am a different character in different languages. I have different enjoyment from them. Sometimes different answers come out of me. Like, I didnt even know that about me. I get to know myself through different languages, actually.

The crowds are very important for tennis. It makes you play better, but it can also make you nervous and that's the beauty of it.

I am very blessed to be able to play tennis, the sport that I love and very grateful for the opportunities to play in the finals of big events, when the season starts you are on the roll constantly and obliged to be committed to daily routines on and off the court.

I'm at the top of my game so, when I win or lose, I don't freak out...I don't think we can call it a rivalry yet. There's just to many great players around.
