Just get someone with a weak foot accuracy of below 3 (Maradona is perfect, scored with him doing this trick) Run towards goal in the opposite direction to which dominant foot he has. So if he's left footed, run towards the right hand side of the goal, then aim a shot in the other corner of the goal (which would normally require the player to shoot with his weaker foot) and he'll do it automatically.
Worked for me anyway. I don't know if they do it if you're too far out from goal though. Not sure.
