Nobody actually played tennis in my family.

Not everybody can like what I do, and if you feel that somebody is coming up closer to you and starting the rivalry and everything, you maybe change your position to him.

I haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.

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.

Tennis players we're always playing in center courts that feel like arenas. And when we get on the court and the crowd cheers your name or salutes you - it's like you're a gladiator in the arena. And everyone is cheering - and you're fighting, you're screaming, during your strokes - it feels like you're an animal, fighting for your life.

My father never talked about the sacrifices that the family made for me.

I never wanted to change countries; it's something that is part of me.
