If you find yourself in a tight space, try using elastico to get out of it. Only players with 5 star skill level are able to pull off such a move so make sure to pick wisely. It takes some timing and precision but if you perfect it, you will become dangerous.
Fifa 12 confuses me. I always have trouble with the advanced moves. The videos you posted have made them a little easier but I still can’t really get the hang of it.
