Rennes manager Julien Stephan has told M'baye Niang to reconsider his decision in wanting to join Marseille insisting all his players need to be "fully integrated in the project".
The profile of the Brittany-based club has risen in recent seasons and went a step further this year after they finished third in the abruptly-ended Ligue 1 campaign because of the coronavirus pandemic.
This gives them a path into the Champions League next season which they will start from the third qualifying round and Niang's involvement will be very crucial after he finished as Rennes' top scorer with 15 goals in all competitions.
