Moses Simon and his Nantes teammates escaped relegation from Ligue 1 on Sunday.
The French side squeezed past Toulouse on away goals in the play-off.
Antoine Kombouare’s team lost 1-0 on the night thanks to Vakoun Bayo’s 62nd-minute strike.
But they kept their top flight status thanks to their 2-1 win in the south west of France on Thursday.
It brings to an end a turbulent season for Nantes in which they had three coaches, including a disastrous and short-lived spell under reviled former France coach Raymond Domenech.
Fans greeted Domenech’s arrival at his first training session in late December with clown music in one of the most memorable moments of the season, and things did not improve much before his sacking in mid-February without a single win under his belt.
A run of four wins from their final five league games enabled Kombouare to keep Nantes out of the automatic relegation places and then beat Toulouse, who stay in Ligue 2.
