My dad has always been very helpful with good advice, and he still helps me. I call him after every single game, and he is very critical, if I am honest with you.

When you are 25, everything comes easy to you. When you get past 35, every training session is a sacrifice. I can't see myself doing that.

If you have a game where you're under pressure, obviously there are going to be a lot of shots on target, and you're going to make saves, but you can't say you played well in a game where you concede five goals. It's ridiculous.

I am happy to take the blame sometimes for a goal conceded if I felt I could do better.

I love football and it's the sport I would really like to play. I've said on national television here that I would really love to play for one of our football clubs when I finished my tennis career.

It took me 35 years of being involved at a decent level of football to become manager at a great club like Celtic.

I just love football.

I'm sure I was insensitive. I'm probably still a jerk at times. But my priority as a freshman was to be good in basketball and play a lot. Not to be the nicest person in the world. I was one-track-minded. I still am.
