I'm Not Fighting With Myself.

I Was Very Competitive. I Hated Losing. No Matter What, I Had To Win.

But Normally When You Talk To Yourself [on Court] You Say; 'i Love You, You're A Good Guy, But Don't Miss Next Time, Okay.'

If You're Losing, Just Be A Man; Be A Man And Lose As A Man.

I've Had A Lot Of Luck. If I Didn't I'd Be Washing Bottles In Russia.

Roger [federer], He Brought Tennis... One Level Higher. Normally He Toys With Everybody. With All Respect To Other Players, He Does Whatever He Wants On The Court Against Them. It's Incredible What Kind Of Game He Can Play.
