I used to make a personal with my own teammates to make sure that I was the best. That's the mentality you need at Liverpool, otherwise you don't last long or you don't play enough. A lot of youngsters have these issues in different areas of the body and I think it's your body adapting to the speed, the tempo, the physicality of the Premier League. You know, when you get these issues and blah blah, you've got to stay mentally strong when you're experiencing these little setbacks because they don't last forever. But they're the part of my career that I didn't enjoy being out, being able to help, missing big games, it's horrible.
