In your matches against Nadal, the narrative has always been that he has the superior mental toughness. Do you think your mental game is under-appreciated?
I know the way I play is more visible than my mental toughness. I really had to work a lot on my mental toughness. Early on in my career, I was quite unstable. If people were going into a match with me, they knew if you could hang with me for two hours, after two hours, you’d probably be the favorite. Because I would run out of gas, or start checking out. It didn’t come naturally for me, the whole mental toughness.
I wanted to create a kind of aura that if people played against me, I was not going anywhere mentally and physically. That took me years to build up. Only when I started to win consecutive Grand Slams, and I was able to show that tenacity week in and week out, that’s when I felt like the locker room was actually starting to respect me. Before that, maybe I had that image [of mental inferiority] sometimes. In the years since, I don’t really think I’ve had this.
My mental toughness has always been overshadowed by my virtuosity, my shot-making, my technique, my grace. That's why when I lose, it seems like, "Oh, he didn't play so well." And when I win, it looks so easy. I had that already when I was a little boy. You know, "Why don’t you try harder?" I mean, honestly I tried everything that I possibly could. Just because I don't sweat like crazy and I don't grunt, I don't have this face on when I hit the shot like I'm in pain, doesn't mean I'm not trying hard. It's just how I play. Sorry.
