• On not getting distracted by women during tournaments: “When I’m in a tournament, I don’t pay attention to those things. As strange as it sounds, I go to dinner with my team, I stay with them. What happens around, the girls, that’s … I don’t want to lose energy for that. If you meet a new person it takes energy, you know? If you meet a girl, I’m not ready to go in relationship with her straight away, so it’s like, What is in my mind? For every normal guy, in your mind is to get the girl in bed. As soon as possible. It all takes energy. In a tournament, I don’t do that.”
• On having sex before matches: “For a woman, I believe it can bring some energy. For men, it’s opposite. I don’t think it’s good.”
• On whether he has a girlfriend, in 2011: “Don’t worry about me. I have my own thing. I’ve never dated a girl. I don’t let her believe that she’s my girlfriend.”
• On his plans to celebrate his 23rd birthday, which came on the same day he won his first-round match at the 2011 U.S. Open: “I will go to sleep as fast as I can. Enough with the celebrations. I’ve had enough celebrations in my life.”
• On having no regrets: “I’ve done all the possible wrong things that you can do in a tennis career. But I’m very happy I made the mistakes that I did. That’s important to understand. They were my mistakes, not others’, and I learned from them.
