When,during a backroom meeting, often with me it says "Recommend that Player X should slow the ball down more often" or "Player Y should be trained to try killer balls often". If I instruct the player to do this, 70-80% of the time they do, but sometimes players refuse. I think you should be able to tell the player to. Can you imagine IRL a Man Utd player telling Sir Alex that his advice was crap and they wouldn't do it? Would not happen.
