Michael Emenalo has left his post as Monaco sporting director.
The Ligue 1 club announced on Monday that the 54-year-old is stepping down by mutual consent.
"AS Monaco thanks Michael Emenalo for his commitment and wishes him all the best for future projects," the club said in a statement.
Emenalo took on the role in November 2017 after quitting a similar position with Chelsea.
Monaco have endured a difficult spell since winning the Ligue 1 title and reaching the semi-finals of the Champions League in 2016-17.
They only avoided relegation to France's second tier on the final day of last season and started 2019-20 last Friday with a 3-0 home defeat to Lyon.
The club have confirmed a reorganising of the sporting sector around a new technical director.
Former Barcelona doctor Lluis Til-Perez has been appointed chief medical officer, while Olga Dementeva will oversee the club's medical department as a whole, "among other things".
Deputy CEO Oleg Petrov will remain in charge of recruitment.
