Chancel Mbemba received offers from Al-Shabab, which were more lucrative than his current terms at Olympique de Marseille. However, the transfer did not proceed because Mbemba demanded that the club pay a transfer fee exceeding 3 million EUR to OM in addition to his salary and a signing bonus.

Al Shabab made a concrete offer to Chancel Mbemba, offering him 4 million EUR per year in salary and a 2 million EUR signing bonus. Mbemba countered with a demand for 5 million EUR per year in salary and a 3 million EUR signing bonus. Negotiations ultimately failed as Al Shabab was not willing to meet his demands.
