All the tricks are in the management section (Game Plan) and it shows you how to assign them to the 'link feint' buttons, with a video demonstration of each. I can't remember exactly how to find the feint setup but it's definitely in the formation screen. It's probably best setting them all up and then hitting the training mode with them.
I tend to just hold LB and flick the right stick in a few directions and hope for the best at the moment, it's always a nice surprise to see something pull off. :lol:
