Empathy is important, openness, honesty, and an understanding for others.

To say a player is past it at 29, 30 isn't right.

We have to learn from the past.

My job is to keep my players fit and fresh for the important games.

I'm not even thinking about going back to play football at all. My mind's made up. I'm done.

My father thought sport was something fun - he didn't know it was a way to make money. Then I won a Mercedes at the world championships and I gave it to him. From the moment it arrived my father said: 'Good, you can support not just yourself but me too'.

People think that there is so much money in tennis, but the reality is unless you're ranked in about the top 50 you don't earn much at all. It is hard to support yourself travelling the world, to be away from home most of the year and to pay for a coach to help you become a better player.

In the history of sport in general, people stick around. Look at Shaun White and Lindsey Vonn just continue on, Olympic cycle after Olympic cycle; that is why they are famous.
