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.

When we want to reach a dream for the second time, you want it to come true, when you try so hard, you are so close to achieving it, it makes things very difficult to live with afterwards.

I retired because I had a knee injury, my cartilage was wearing out, it was painful and I couldn't put in the four hours of practice each day that I needed to.

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

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.

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.
