Olympique de Marseille has suspended coach Andre Villas-Boas hours after he offered his resignation to the Ligue 1 club.
The French club announced the suspension on Tuesday after Villas-Boas said he did not agree with the club's sporting decisions.
"This protective decision has become inevitable given the recent repetition of actions and attitudes which are seriously damaging to the Marseille Olympic institution and its employees," Marseille said in a statement.
Villas-Boas had criticised the board for recruiting a player he had rejected and for informing him at the last minute that another was leaving as the transfer window closed on Monday night.
"I offered my resignation, saying that I did not agree with the sporting policy," Villas-Boas told a press conference earlier on Tuesday.
Villas-Boas, who last month said he would leave when his contract expired at the end of the season, referenced the club's signing of Olivier Ntcham from Celtic and the departure of striker Nemanja Radonjic for Hertha Berlin.
"We ended the transfer window with a new player. He is a player that I had said 'no' for," Villas-Boas said.
Marseille said they were considering sanctions against the Portuguese coach, following disciplinary proceedings.
"The comments made today at a press conference ... are unacceptable," the club added.
Marseille were knocked out of the Champions League at the group stage and sit ninth in the French league, 16 points behind leaders Lille.
