Hmmm I am the home team and the opponent has two important games this week. He isn't using his best players. I do understand game shape. Their is no underlying theories underneath gameshape it merly means that it is how fit your players are for games?
Haha yes, you understand what game shape is. I know what a rocket ship is, doesn't mean I know how it works. They are saying you as the manager control the minutes of the players, thus you can control their game shape. Which you are doing poorly.
