just tell them you want them to teach them!
its more down now to the coaches... pick your best attacking coach to teach it to him! the players no longer refuse, depending on the coaches stats as well I assume depends a great deal whether or not the player will end up learning the move:
1) Determination
2) Motivating
3) Discipline
I have not tested this theory yet, however it could have some truth
Would make things a lot simpler if that is the case
