Didier Deschamps intends to make a host of changes this summer as he aims to bring the French title back to Marseille.
Deschamps led Marseille to the Ligue 1 crown in 2009/10 but they were pipped by Lille last season.
The former Marseille midfielder had been linked with the Roma job this summer before signing a two-year contract extension until 2014.
So he has now turned his attention to freshening up his squad, accepting the sale of influential midfielder Lucho Gonzalez could finance several new signings.
"I need some fresh blood so there will be three or four reinforcements," he told L'Equipe.
"I want to regenerate the bench too, let some fringe players leave.
"I want Lucho to stay, but I won't refuse his departure if all the conditions are gathered.
"Lucho is a very good player, very professional, even if during the last six months he was not effective enough."
Andre-Pierre Gignac also had a disappointing season, failing to live up to expectations following his summer switch from Toulouse.
But Deschamps hopes to get the 25-year-old striker firing on all cylinders again after warning he must adopt a more professional manner.
"I've made him aware of things," added the Marseille coach.
"I repeated and repeated again, even being harsh with him sometimes. He will now either be aware of it or he will lose his way.
"I am here to help him, but it is up to him to make efforts.
"This season, with (new club president) Vincent Labrune on board, any misbehaviour will result in fines and I will remind the players of certain rules."
