I can remember my father gave me a huge history of football for my 12th birthday - I used to read that a lot. I can remember thinking it was cool that something I was interested in even had a history. Most things I loved didn't.

Go back through football, and you will see that the team with the best defense wins.

A lot of football success is in the mind. You must believe you are the best and then make sure that you are.

The best thing that I did was get myself out of an environment that was toxic to me and to my mental health. That was through retiring from football.

I threw up before every single football game I played, and I did so up through my NFL career. It was good pressure. It was pressure to be good. It was pressure to be the best. It was pressure to want to win.

The best football is always about expression of emotion. Always.

I see myself as the best footballer in the world. If you don't believe you are the best, then you will never achieve all that you are capable of.

In football, even when you do your best on the pitch, you can win or lose. That is the nature of the game.

Football is my profession now. I'm getting married in August... It's a new experience for me as someone just getting out of college. I still have the same attitude about football I always had. I play hard. I enjoy practice. I'd rather be throwing in passing drills than sitting around and watching TV.

Contracts are not a holy relic in football. You can like this attitude or not, but it's the truth. Sometimes you have to think about if it is meaningful to try out a new impulse.

I always think we have to be cautious with our attitude to refereeing the professionals and the people in the football family.

You can't be Allen Iverson on a football team. And even Iverson got run out of Philadelphia when he was still a spectacular talent because the Sixers got tired of the headache and his bad attitude.

Even when I was growing up as a young boy, when I was playing schoolboy football, there were other guys who were as good as I was, maybe some even better technically. But I was prepared to stick to what was going to make me become a professional football player when I left school, and that was a lot of sacrifice and because my attitude was right.

My attitude as a footballer was to always be prepared - make sure you're the fittest and know who you're up against. And that's exactly how I treat the media side.

Foreign football is different and it has helped me evolve and mature, improving my attitude.

I want to work with kids and help develop them, show them the right way, the right morals and attitude into how to become a better footballer. Australia has many different cultures but I'd like to bring in the indigenous style, bring their competitiveness, athleticism and raw ability into the frame.

Things don't always go your way in football: there are always good and bad times. At the end of the day, you have to have a positive attitude and a strong mentality and not let any setbacks get you down. And that's what I've done - I've tried to keep my composure, even when things aren't going the way I'd like.

I played football for a long time when I was a kid, and then I went to art college and turned my back on it. Because of that, my toes are mangled; they've been broken. They're like hooves or talons. They're disgusting. I'd never get them out.

Football is an art, like dancing is an art - but only when it's well done does it become an art.

For a 20-year-old kid to be taking on Liverpool Football Club over a contract. To the pit of my stomach that just winds me up, it angers me.

I do play football no-holds-barred. Any edge I can get, I'll take. I'd grab a face mask only in a fit of anger. Uncontrolled anger is damn near insane.

I've learned that football sometimes was an outlet. It was a way for me to release anger, release frustration.

My mom's whole side of the family, they're all Packers fans. My mom's a Bears fan. My stepdad is a Vikings guy. So that gets ugly. My mom sits upstairs watching the Bears game; he sits in the basement. They can't watch it together. Football's a violent anger in our family dynamic.

In baseball, you have to remain calm, cool, and collected. In football, you can let out a little anger sometimes. It was a fun game, and I liked it, but I knew in my heart I was going to play baseball.
