If you know anything about domestic football in Argentina, you'll know that Boca Juniors and River Plate are great rivals.
The two sides, both from Buenos Aires, met in a 'friendly' recently - and predictably, things kicked off.
Four players were shown red cards in the game which contained a staggering 40 fouls.
Former Manchester City striker Carlos Tevez also conceded a penalty which saw River Plate score the only goal of the game.
For Tevez's Boca side, the sending-offs followed two red cards in a 4-2 defeat by Racing Club earlier in the week.

Not bad going for a friendly match, eh?
