French giants Olympique de Marseille have added eight new faces to date during this transfer window.

Permanent deals, near-record signings, loans-to-buy, contingency plans and straight loans among those deals.

Mattéo Guendouzi and William Saliba have swapped the Emirates Stadium for Stade Vélodrome, while Gerson returns to Europe with a foray into French football after a successful spell with Flamengo.

2021/22 could be an OM remontada under firebrand coach Jorge Sampaoli - or a complete car-crash.
