The Cameroon forward, signed from Brentford, takes over the slot last held by Raphael Varane, prior to the Frenchman leaving the club at the end of the 2023/24 season.
Matheus Cunha has taken on the no.10, while fellow new recruit Diego Leon has been handed the no.30.
With Victor Lindelof exiting on a free transfer and vacating the no.2 jersey, Diogo Dalot has moved into his place.
The right wing-back switched from the no.20 he has held since joining the Reds in 2018, although he did have a loan spell at Milan in 2020/21.
