[header] How to do a ronaldo chop [title] Leap over the top of the ball. [step] This isn't a big jump, more of a hop-step to let you get your feet in the right position for the trick. [substeps] This is a trick you do while running, so you may need to slow down slightly before your leap in order to keep the ball close by. 
Don't take too much time to slow down, maybe a step or two, or else the defender will know something is coming. If you go too high, the defender will take advantage, and knock the ball away.
