When you see the coals, your first reaction is to think 'my God, that's going to burn me', ... If someone can teach you how to put that out of your mind, how can that fail to make you a better footballer? You may not be able to walk afterwards, which is a risk, but it's one we're willing to take. You have to stop thinking about your family or anything else that is going on outside the game. You can get better at it and the more experience you get the easier it becomes.
