I understand that the results I've had in my career, or I'm having now, they are very good. And that gives me confidence, of course, but I do not feel invincible.

I'm very fortunate to have the support of the people around me, I feel happy because my wife helps me and people who are close.

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.

I've had my ups and downs in my private life.

I love being around people who care about me, and I care about them.

I have been through two wars in my 24 years, and I know what it's like to be without anything, to see the bombs flying above your head.

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.
