“Managers can’t perform magic, although some people seem to think they can. They’re not David Copperfield or Harry Potter. They can’t work miracles or sprinkle some magical dust to make players know how to play football. Spending hours on analysis isn’t very useful. It doesn’t put you in better conditions to win the game. The tactics, the schemes, they’re all bull***t. Of course tactics matter, but players win the game. For 45 minutes at a time, players make their own decisions. Football is a continuous sport in which the coach has barely any influence, less than in any other sport. …”
