It's interesting that I had such a close relationship with my grandfather. Because your parents always judge you: they say, 'You shouldn't do this, you shouldn't do that.' But with your grandparents you have a feeling that you can say anything or you can do anything, and they will support you. That's why you have this kind of connection.

You have to believe on the court. In the end, it's mental. In these moments against a great champion like Rafa, you have to believe. It's all about stepping in and taking your chances. I always believed, but it's a process of learning.

I try to enjoy what I do, and every moment of the life that I have is a blessing. What else can you do but to be happy and try to bring that joy to the other people around - especially in the tournaments. Everybody has bad days. I'm not always funny or laughing.

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.

Tennis is a mental game. Everyone is fit, everyone hits great forehands and backhands.

Imagine a part of the U.S.A., from which the U.S.A. started - where is the cradle of your history? This is Kosovo for Serbia.

It is very important and my success very much depends on the harmony that I feel in my private life. It is essential for me to be happy in my private life. And if it continues, I am able to continue playing tennis.
