Tennis was always sort of a - a learning. It was a vehicle for me to discover a lot about myself. And the things that I sort of discovered at times I not only didn't want to see it for myself but I certainly didn't want millions of people to see it.

I've been criticized for not having perspective in the past and I thought that of myself many times but not there.

I think one of the greatest joys I have now in my career and in my profession is to be playing at an age where I can appreciate it more than I used to... It's a whole different lens you look through the older you get.

I had my moments for sure but I wasn't confrontational. And sometimes you get on the court and you'd find yourself very confrontational. It was all a discovery.

I had concussions as a kid playing football and basketball, and know what it feels like and to have someone say 'Just rub some dirt on it, and get back in there.'

I just love football.

I always said that I took a lot energy, a lot of time for me to recover and come back to the sport and join back in F1, but I would like to stay.

I've been in football a long time now and I've seen plenty of managers and players come and go. It is part and parcel of the game.
