M'Vila has been hailed as one of the best midfielders in Ligue 1 last year, and is rumoured to be top of the list of transfer targets for Arsenal, with Liverpool also reportedly interested.
"He is ready to leave," Dreossi told RMC.
"For now there have been a few signs of interest, but no concrete enough offers for M'Vila to leave.
"The transfer window has only just opened, so we will wait for the right offer to arrive.
"He has true value, even if he put on an average European Championship display."
Arsenal seemed set to complete a deal for the midfielder before Euro 2012, but the move didn't materialise.
