The 25-year-old arrived initially on loan in November with the move made permanent in January 2014, putting pen-to-paper on a three-and-a-half year deal.
After coming through the youth ranks at FC Metz, Gestede spent a year on loan gaining experience with AS Cannes, scoring four goals in 22 appearances, before returning to Metz in 2010.
The summer of 2011 saw the striker make the move across the English Channel to join Cardiff City after a successful trial.
Gestede more than played his part in Cardiff's 2012-13 promotion campaign, scoring on five occasions as the Bluebirds lifted the Championship trophy.
A regular at youth levels for France up to Under-19s, Gestede has since opted to play for the country of his parents, Benin. He has two goals from three appearances for the West African nation.
