Check out this insane footage from the Bosnian League second division of an vexed footballer trying his best to knock out the referee.
Goalkeeper Romeo Mitrovic's emotions ran high when he received a yellow card and his instant reaction was to try to take the referee's head clean off. Thankfully for the ref, the haymaker right hook did not find its home because of some excellent head movement by the official. This gave him ample time to scurry away from the aggressive shotstopper, who has been capped by Bosnia, and out of his striking range.
One can only assume that Mitrovic was handed at least another yellow for the second offence. I'd hate to think how he reacted to that. Here's hoping the linesman didn't get floored by a spinning back fist as he was presumably escorted off the pitch.
