Delort completed his move from Montpellier before the end of last month's transfer window for a fee believed to be in the region of 10 million Euros (11.8 million US dollars), and the 29-year-old has linked up with Galtier, who won the Ligue 1 title with Lille last season, at Nice.
The Algeria international had previously undergone spells at French clubs Nimes, Ajaccio, Metz, Tours, Caen and Toulouse, which were punctuated by brief moves abroad at Wigan Athletic in England and Tigres UANL in Mexico.
Translation of Delort's quote:
"I have always liked this head coach (Christophe Galtier). To be able to play for him and to be one of his warriors, I am happy. I have no doubts that he will help us to progress and I hope he will take us as high as possible."
