As a player, my mantra was: practice makes perfect. It's the same now I'm a coach, but I'm not looking for the next Dennis Bergkamp. I want to improve players and it wouldn't be a challenge to coach my younger self.
By that I mean I was a player who could solve problems myself - I didn't really need a manager or coach for that. I did my own thing but I was always professional about it. I was respectful enough to the manager to play in his philosophy, in his system. None of them had to ask me to change the way I played or trained.
