14. Joey Barton vs. Ousmane Dabo
Dabo hates Barton for this and no wonder because it’s one of the most brutal beatdowns on this list. Currently managing the lower-league soccer side Fleetwood Town, Barton had a terrible reputation as a player for his crazy behavior. The FA and police have banned and arrested him multiple times.
Barton squared up with Dabo on the Manchester City training field. He sucker-punched Dabo, sending him to the ground. Then he followed up with ground-and-pound. A court gave him a four-month suspended prison sentence while the league banned him for 12 games with six suspended.
