If you lived the doubles, as I did, which was very stressful, you are sitting down in a chair experiencing a match without being able to hold a racquet in your hands.

But whatever happens, when you leave London you feel like a winner because it's a great venue and it's so nice to be there with all the guys.

Suddenly in the end when it's over, you feel a big weight on your shoulders. That's the role of the captain. Unfortunately, it's sometimes like that in sport.

When you are very little tennis should be fun, it should be a game.

Anything is possible as long as you have the passion.

More than specific memories of achievements, for me I remember the feeling you get when you were just at your very best - when you felt like you were floating across the court and could put the ball wherever you wanted.

But I still serve pretty big and that's one of my biggest weapons, so if my shoulder holds up and I can count on it, I can win a few matches and then you never know how the other guys are going to react to the fatigue and the length of the matches.
