Former Liverpool and Crystal Palace defender Mamadou Sakho is in trouble.

The centre half is facing the sack at French club Montpellier for attacking his head coach.

Sakho is said to have allegedly gone at his manager Michel Der Zakarian in training.

Per French media reports, Der Zakarian did not allow for a foul on Sakho in a training game.

Sakho was then storming away, with his head coach stating the session was not optional.

The defender then came back onto the field and was involved with Der Zakarian in a physical altercation.

French newspaper L'Equipe states that Montpellier are even considering ripping up Sakho's contract.
