Christophe Galtier has stepped down as head coach of Lille just 48 hours after they won the French league title.
The 54-year-old helped Lille secure their first Ligue 1 championship since 2011 on Sunday, finishing one point ahead of Paris St-Germain. He has now been linked with Nice and Lyon jobs.
He had been expected to leave after new owners took control of the club halfway through the season.
"I simply have the deep belief that my time is up here," he told L'Equipe.
He said he was moving on to avoid "falling into a routine".
The announcement came after Lille took part in an open-top bus parade in the centre of the city to celebrate the title win with fans on Tuesday.
Galtier took over at Lille in December 2017 from current Leeds manager Marcelo Bielsa - with the side in relegation danger.
After keeping them up he then took Lille to second- and fourth-place finishes over the next two seasons before this season's title.
