I know I can't get them back. That's why I'm making a suggestion. In real life you can change your mind you know. "Hey Mike I want you to work hard on free kicks" (1 month later) hey mike, scratch that work on penalty kicks instead. Seem pretty simple to me.
Don't compare this game to real life though. Mike will be better at free kicks, gradually getting better over that month. In the top eleven world the player only gets a free kick ability once the training is complete
