Lee Bowyer and Kieron Dyer
This remains one of the most notorious incidents in Premier League history. These bitter enemies played for Newcastle United when things weren’t going well on the field. They traveled to Birmingham where they played Aston Villa but quickly fell behind. Then things got even worse for Boweyer, Dyer, and their team.

Allegedly, Bowyer made an aggressive comment when Dyer refused to pass him the ball. The next thing that everybody knew was that they were punching each other and ripping their shirts. In the end, the confused referee sent them from the field. It was a humiliating incident for both men but it became iconic (via The Mirror).
