Anyone who believes that only twenty-two players, eleven from each team, participate in a football match is mistaken - in fact, two more people - team coaches - are directly involved in the game. They lead the game from the first to the last second of the match and experience every episode of it. As in any profession, there were and are truly great people among football coaches. Some of them went down in the history of football with their epoch-making discoveries that changed the very essence of the Great Game.
