Deschamps is unhappy with the lack of funds available for him to strengthen his squad this summer.
“You should know that the directors of Marseille have known my position since May 25 after a meeting in Paris,” he told Le Phoceen.
“I am someone [who] always behaves well and will always be respectful to the club. I know what it means to me.
“I’ve taken this decision because it’s impossible to work under these conditions. It would have been detrimental for both the clubs and players.”
