If you are thinking about mistakes during games then you are not concentrating on what is important which is the next shot or the next cross or whatever you have to deal with in that game. The mental side of things is massive, probably the biggest.
When I'm shouting at the defence, subtitles come up in front of the goal.
You play all your life and train all your life and then you are not playing. It's not easy to deal with. But you can't roll up in a ball and hope it goes away. You have to take it on the chin and train hard and be prepared to play. We all know the game changes in an instant and anything can happen so you have to keep the hope that comes your way.
