Marseille have provisionally suspended manager Andre Villas-Boas pending disciplinary proceedings after he criticised the signing of Olivier Ntcham from Celtic and offered his resignation, reports Sky Sports.

A club statement read: "Olympique de Marseille announces the pending disciplinary proceedings of Andre Villas-Boas.

"This decision has become unavoidable given the recent and repetitive actions and attitudes that have seriously harmed Olympique de Marseille and its employees, who devote themselves to it on a daily basis.

"The remarks made today during a press conference in regard to Pablo Longoria, general manager in charge of football, are unacceptable.

"His exceptional achievements should not be questioned and, on the contrary, were welcomed by all during this winter transfer window, which was affected by an unprecedented crisis.

"Possible sanctions may be taken against André Villas-Boas following disciplinary proceedings."
