@ trying to make it all about: "Did he make contact with the ball or not?!" We're not talking about a keeper who reached with hand to push the ball off the foot of the attacker! We're talking about a player being in a place where he shouldn't be, getting in physical contact with somebody outside the field, and trying to get the ball off a kid by kicking him when he's lying on the ball..
Just look at this gif again (which is
not a still picture, and is much closer than the other gif):
You just can't do that. It's laughable actually to think that he shouldn't get at least 3 games ban.
