I'm Only Superstitious On The Tennis Court.

I Play Because I Have Fun, If I Don't Have Fun On The Court, There Is Something Wrong. I Am Just A 19 Year Old Boy That Likes To Do What He Likes, Nothing Else.

If Somebody Says I Am Better Than Roger, I Think This Person Doesn't Know Anything About Tennis.

I Learned During All My Career To Enjoy Suffering.

I Am Satisfied The Way That I Am Playing. Is Obvious That There Is Always Things To Improve.

I've Stayed Calm When I'm Winning And I've Stayed Calm When I've Lost. Tennis Is A Sport Where We Have A Lot Of Tournaments Every Week, So You Can't Celebrate A Lot When You Have Big Victories, And You Cannot Get Too Down When You're Losing, As In A Few Days You'll Be In The Next Tournament And You'll Have To Be Ready With That.
