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.

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.

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.

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.

You can be a little lonely because it's an individual sport.

To be a professional tennis player you need to put in these sort of hours.

There are some guys you have problems beating because of their style - I always had difficulties with guys like Michael Chang and Andre Agassi because their returns were so good and they played so well in defence.
