The secret is to work less as individuals and more as a team. As a coach, I play not my eleven best, but my best eleven.

People of mediocre ability sometimes achieve outstanding success because they don't know when to quit. Most men succeed because they are determined to.

You can't win unless you learn how to lose.

Concentration comes out of a combination of confidence and hunger.

Once you learn to quit, it becomes a habit.

Obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
