"It's not about the winning or losing but on how you played the game," they say. And referring to being sent off due to headbutting or elbowing, 2014 World Cup in Brazil is no different from the other World Cups in the past.
Alex Song of Cameroon was sent off from the game after giving an elbow to Mario Mandžukić of Croatia. Cameroon suffered a 4-0 loss against the latter.
Perhaps it runs in the blood as what other people said. Remember Rigobert Song in both the 1994 and 1998 World Cups? He was red carded as well.
