Will Still has resigned as RC Lens boss to return to England.
Still, who led Lens to an eighth place finish in Ligue 1, said he wants to be closer to his partner Emma Saunders.
Sky Sports presenter Saunders has been battling a number of health issues over the last year.
She was being treated for thyroid cancer and is also recovering from a brain infection called encephalitis.
He said: “I won’t be the coach of RC Lens next season.
“It was the last season at Bollaert, for multiple reasons.
“The main reason that pushed me to make this decision is the fact that I need to go home.
“Everyone is well aware of what happened in my life. That’s why.
“I had a lot of fun, I think we achieved great things despite everything. I’ve been in France for four years, four years that I’ve experienced intense moments.
“The logical choice is that I get closer to my wife for her well-being too.”
Saunders attended Lens’ final game of the Ligue 1 season, which they won 4-0 against Monaco.
She shared a picture of her and Still on the pitch following the game.
Fans have previously shown their support for Saunders with a banner that read ‘Courage Emma et Will’.
Still will return to England and could immediately take a job in the EFL.
He is on Southampton’s list as candidates to take over this summer following their relegation from the Premier League.
The Saints crashed back down to the Championship, having taken just 12 points in 36 games this season.
Still made a name for himself as Reims manager when he was just 30 years of age.
He did not even have his UEFA pro licence, which cost the club £22,000 per match.
