He played for Nice after leaving Liverpool on a free transfer in 2016.
Balotelli, who has also played for Inter Milan in his 12-year career, scored 42 goals in 64 games in his first two seasons in France.
But he was dropped by Italy in September 2018 and has not scored in 10 games for Nice this season.
Their main strikers Valere Germain and Kostas Mitroglou have scored just three league goals each so far this campaign.
Boss Garcia has ruled out a start for Balotelli when Marseille play Lille on Friday evening.
