You can find flaws in Agassi and Sampras, but Federer has none.

New York is a fantastic city.

You can find flaws in Agassi and Sampras, but Federer has none.

It is very hard for me to switch from clay to grass.

All in all, I think Kazan is Russia's sportiest city after Moscow, leaving all the others far behind.

Everybody is smarter from outside of the court.

Five sets is a kind of lottery. Anything can happen.

I achieved what I want to achieve and I want to continue doing something else.

I can improve it a little bit. But it's my head, it's the way I am. So at the end of the day, I will be who I am and I will win how much I can win.

I could be the best looking guy in the Duma, but that's only because all the other guys are over 60.

I could go and make commercials left and right and pretend like I am a celebrity, but that is not me.

I could pose in fashion commercials as a high society star but politics is a new way of life.

I definitely want to get out of tennis and try something completely different.

I didn't change the world.

I don't care about losses anymore.

I enjoy my life.

I give up on spending time on these courts; I give up on practicing before the tournament I hate. I hate this.

I hate competition.

I just want to make everyone happy.

I love tennis, but I just don't like grass.

I pass through the difficult moments in life, really difficult times on grass, during my seven years of my career. All of a sudden I felt comfortable.

I think as a guy you need a little bit to be on your own from early on, to start to live your own life, and try to understand what is going on around you, you have to be able to survive.

I think it's difficult to be No. 1. 'There's too much attention, too much expectation from other people.

I try to do my best to have fun off the court.

I was making comebacks every single year. That makes it difficult mentally. It causes a lot of stress.

I was very competitive. I hated losing. No matter what, I had to win.

I wish I could have won a lot more tournaments, but I got injured every time I played well.

I'm different than another person who wants to lay back and do nothing for rest of the life and talk nonsense on ESPN... I will not do that. I want to achieve something else.

I'm not a materialistic person.

I'm not fighting with myself.

I've had a lot of luck. If I didn't I'd be washing bottles in Russia.

I've had good times and bad times. That's me. That's how I am.

I've lived my life the way I wanted to, whether scaling the mountains, partying long into the night or having fun playing soccer.

I've realized I can't waste any moment being unhappy.

If I was the type of person who had tennis, tennis, tennis all the time and I went to bed and ended up dreaming about tennis, I would go nuts.

If you're losing, just be a man; be a man and lose as a man.

It was really impossible to break through in Russia. We couldn't buy any balls. We really didn't have any courts, no rackets, nothing. And no people to practice with.

It's a pity that the tennis is really going down the drain. Every year it's getting worse and worse and worse. There has to be a radical change, and I hope it will be really soon.

It's too many questions about what I'm going to do, why I'm retiring, and this and that. So I answer the same question, I don't know, a thousand times.

Me, I don't need money.

My mother said I would have more chances to become a tennis player than a football player.

No matter what happens, tennis is still tennis: You can see a lot of great matches, a lot of new people.

One of the most important things, actually, when you're playing on grass, is to move.

Probably I'll not be so successful if I will keep everything in myself inside of me.

There is no such thing as a perfect player; it doesn't exist.

There's a lot of things in life that we don't know why they're coming exactly at this moment.

We live because of the dreams.

Whenever I am losing, it's like, 'It's his fault'. And whenever I'm winning it's like, 'That's us'. That's the team, the people.

You cannot change me; this is the way I am.
