The striker had a good first season with Marseille following his move from Toulouse in 2010, but scored just once in his second term and was linked with moves away from France.
Everton, Fulham and Blackburn Rovers were all linked with the Frenchman, but a return of 14 goals on 2012-13 helped Marseille to finish as runners-up to Paris St-Germain in Ligue 1.
The 27-year-old, who still has two years to run on his contract, says his form has helped improve his outlook.
"It has been my best season since I was in Toulouse. I got my revenge on last season," said the French international.
"I cannot see why I could leave and where I could find a better place in France.
"I am sure the club will make needed efforts to get reinforcements and to end in top three next season. Nowadays I feel very well in the club of my heart."
