Just want to mention, the wrong foot animation from a standing still position is a Glitch - not a mistake. You can clearly see it. You slightly press one direction, they guy doesn't move, then you press the opposite direction and the buy goes into a "bust a move" dance and the wrong-foot animation triggers. But you were not moving into any direction so it shouldn't trigger really.
There is a way to over come it, and that is to be very patient and basically not press any direction before the ball clearly on its way back over the net. Then you can move.
