I know, it makes the video look cooler. But if he really wants to turn heads he needs game footage or training where he's out of his depth.
We used to do this training called "Georgia State Walk-on Breakers" and it's really complicated and difficult, but to summarize; in the end the GK is shuffling from side to side trying to stop shots, crosses, and 'breakaways' with a handicap. Sometimes it was one hand only, one foot, blind folded or no hands.
