Andre Villas-Boas has offered his resignation at Marseille after the Ligue 1 club went against his wishes by signing Olivier Ntcham. 

Ntcham joined on loan until the end of the season from Celtic on deadline day despite Villas-Boas saying he did not want the player. 

The former Tottenham and Chelsea boss consequently felt his position was no longer tenable and offered to leave, citing a disagreement with Marseille’s sporting policy. 

Villas-Boas said the training ground being attacked by angry fans at the weekend "had nothing to do with it" and that he was awaiting a response from the club. 

"I submitted my resignation saying that I did not agree with the sporting policy. I don't want anything from OM. I don't want money," he told a news conference on Tuesday. 

"I'm waiting for an answer, it could be no and then we would continue. I don't want any money, I just want to leave. 

"[Signing Ntcham was] a decision that was not taken by me, I learned of it this morning from the press. He is a player that I had said no to. He was not on our list. 

"The results – it's my fault. I'm very upset. But if there's something you cannot touch, it's my professionalism. I cannot accept this. This club has already been through a couple of messy years in terms of transfers."

Marseille have won just one of their past eight Ligue 1 matches, with a 3-1 loss at Monaco last time out their third straight defeat. 

Their meeting with Rennes on Saturday was called off after fans stormed the training ground in protest. 

Villas-Boas accepted the club's request for time before making a decision on his resignation and he was still preparing the team for Wednesday's trip to Lens. 

"I'm focused on Lens. We continue until the board lets me go," he added.
