Alex Ferguson, Manchester United coach of many years, once said: "When critics of our game are parading their theories about the attributes that make some teams better than others, it always amuses me their eagerness to focus almost exclusively on techniques and tactics comparisons. We often see them discussing football in abstract terms, forgetting that in reality it is played by flesh and blood creatures with feelings. Tactics is important, but this is not what wins games. Games are won by people. "
