Yes they do. When using the Tactic Creator and setting a player to a certain role in the tactic, it means that you will give him some instruction that the game has labelled as the instructions of a role, like a poacher. So if setting him as a poacher, it means that you want him to make lots of runs from deep, run with the ball and move into channels rather than to hold up the ball and act as a link man.so, player instructions don't have significant effect in game ?? maybe you can suggest additional instruction for poacher ?
Another example:now i see, thanks for it
