It's a move used to nutmeg, which obviously wasn't useful in this case because Khan went sideways. Had Khan been left standing or the move done earlier you would all be praising this guy like crazy. He was a bit hasty in the execution. I somehow doubt you need to press all these buttons to perform it, but in the other hand i am surprised that there is such a move available in which case it does make sense that it should be so difficult to execute. I also think that Konami should inform people of such moves...
This is like nudging the ball forward when you sprint but it can be done whilst you're running forward so it can be used to meg players directly in your path wiothout pushing the ball too far out.
Thanks and well done, XR666.
