I physically feel very fit. I’m very motivated to keep on playing on a very high level. I’m going to try to use these years in front of me to fight for the number one of the world and fight for the biggest titles.

In my case, I can sincerely say nothing is impossible.

My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.

Obsession is a negative word, I do not think that obsession can bring positive things. Not only in tennis but, I mean in any situation of life.

I know that success does not come at once, it is not a thing achieved overnight. It is the result of many, many, many years of working and trying to achieve goals.

What I learned as a young child continues to have a tremendous impact on my life today.

You can not say you're unhappy because you have to travel, have to play this tournament, having to play sports ... You can't because you chose to play it and you love it. I'm tremendously grateful for the support I have received from my family and the close ones.
