23. Zlatan Ibrahimovic vs. Oguchi Onyewu
Zlatan is an immensely talented soccer player, but he’s also one of the biggest divas in the game. Several teammates have experienced his fury. First of all, he threatened to break Rafael Van Der Vaart’s legs at Ajax. Then he punched Jonathan Zebina in the face at Juventus. In sum, ‘Ibra’ just didn’t care.

But the former LA Galaxy superstar’s most notorious incident was with his fellow former AC Milan teammate Onyewu. He headbutted him during practice, prompting a furious fight. The pair were on the ground landing knees, punching, and kicking each other. After, Ibrahimovic said they wanted to kill each other.
