If AZ Alkmaar goalkeeper Esteban Alvarado knew the FIFA rulebook, he knew that any attack on a fan would result in a red card and automatic ejection from the pitch. But that didn't stop Alvarado from making one brave spectator pay for even trying. With some Mortal Kombat-like aerial moves and a couple of kicks while dude was on the ground, the AZ keeper made sure everyone else knew not to mess with him, no matter how many goals he allows in a match.
