Aaahh South America. Your weather is beautiful and your footballers are lunatics.
This clip comes from a Copa Libertadores match between The Strongest and Arsenal de Sarandi in which The Strongest ran out 2-1 winners.
Drawing 1-1 and already down to 10 men, Arsenal brought on Argentinian forward Emilio Zelaya.
7 minutes later, Zelaya was off for an early bath after punching an opponent in the face.
His idiocy meant his team had to hold on for a draw with 9 men. They were unable to do so and lost 2-1.
Watch supersub Zelaya assaulting an opponent below (skip to 0:44 for the punch):
