Remy seals Marseille switch
The player later passed a medical and signed a five-year contract for an undisclosed transfer fee, Marseille said in a statement on their website.
Marseille, who have lost their first two league matches this season, desperately need a striker to replace their Senegal forward Mamadou Niang, last season's Ligue 1 top scorer with 18 goals, who has left for Fenerbahce.
The 23-year-old Remy, who has two caps, started at Olympique Lyon and joined Racing Lens in 2007 before moving to Nice the following year. He scored 14 Ligue 1 goals last season.
