I once scored a spin goal (like those you see in handball often). The goal was empty (one of those small goals, less than a meter wide) and I was with my back to the goal about 7-8 meters away to the right of it, two guys were running back, i was just standing there and as they were passing by the ball came to me and I hit it with the outside of my (left) foot, it went past them and as they turned to me it spinned and slowly went into the goal behind their backs. One asked me how the fuck i scored without them noticing the ball. Tried it a few more times but couldn't do it. Id say thats better than your corner goal tbh
