The Frenchman will continue his career in the Premier League.
Nizzi's central director, Jean-Clair Todibo, as previously reported, will be arriving at London's West Ham this summer.
According to journalist Fabrizio Romano, the 24-year-old Frenchman successfully passed a medical examination at the Premier League club, where he transferred on loan with a mandatory buyout clause for 40 million euros.
Nice also takes away part of the cost from the potential upcoming sale of Todibo.
It is significant that Jean-Clair Todibo will play for Nice in 2021. Before turning to France, the center back stretched two years in the Catalan Barcelona.
