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.

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.

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.

I had a coach that was not a great player, but he taught with kids and juniors so that by the time he was 50 he was great. He helped me make the top 5 in the world and yet he wasn't a great player himself.

Anything is possible as long as you have the passion.

I think our strength is this strong relationship we have all together.
