Yeah. I just hope he discovers that plan B we never found last time.
Interesting and fair point. Carlo Ancelotti, Bayern Munich's coach, touches on the matter in the current edition of "World Soccer". The interviewer says: "You are very composed in your technical area. Is it because a coach can't really influence proceedings from the sidelines?" Ancelotti replies: "During a game you can't do anything.
It's up to the players to adjust and win. You can't change much from the touchline.
At half-time it's a different story. Most of my work is done before a game, when you have the opportunity to prepare the team and set out the strategy." (The italics are mine.)
In other words, you need to devise a Plan B for that particular opponent on the training pitch, before the fixture. If you don't have one, and things go wrong early in the first half, you effectively waste half the game because the coach can't do anything until the half-time team talk. And if things go wrong early in the second half:
If what Ancelotti says is right, Simeone-style touchline histrionics are a waste of time and energy. But surely, a coach can get a message to the players during the game, either via one of the wide men (who would then talk to the captain) or when the players are taking water, during a stoppage for an injury.
