Aston Villa boss Martin O'Neill and Nigel Reo-Coker clashed in an amazing training ground bust-up yesterday, it has been revealed.
The Sun says it followed a heated exchange between the Aston Villa manager and his midfielder and the pair eventually had to be separated by shocked players.
One stunned onlooker said: "It was really heated and at one point they fell to the ground grappling with each other although no one was throwing punches or anything like that."
