The day I stop feeling the pressure and I'm just enjoying myself and taking it easy is when I'm 35, asking for a wild card and playing mixed doubles with Arnaud Clement.

This trophy is so special in the world of tennis and it feels great.

If you are not physically strong, it's difficult. But at the same time, I think you need something more than that; you need to vary your shots, as Justine has been able to do in Amelia or Charleston, where she beat her -- I can't remember where it was on clay. So you need this kind of thing. But of course if you're not fit, you'll never make it through.

The more kilos you have to move around, the more it weighs on your knees. Then of course in terms of stamina, the way you move around, it's a little extra. It might not be much, but when you exercise with two, three extra kilos, you can feel a difference; it's important.

There were many occasions in my career where I could have given up, where I asked myself whether I would ever make it.

I have been amongst the best players in the world for 8 years. None at that level played as many ties as I did.

Unlike in my young days I'm not able to eat, drink and sleep tennis.
