Training special ability

[Paddyjack]

I know there are some threads about training positions efficiently, like MC, ST, etc using a good set of training that cover the important skils for that position. But what about when you want to train a special ability such as free kick specialist? Is there a set of specific trainings to get the most efficient training of a special ability, or is it just that you start the ability and then train whatever until you reach 40 pts?
