The Ligue 1 side barely passed up securing a Champions League spot for next season, which implies they are probably going to endorse deals to raise money.
Osimhen and Gabriel are two of the team individuals that have pulled in a great deal of consideration from European clubs.
The Nigerian has been connected with Premier League heavyweights and Napoli, while Gabriel has been related with Everton.
“I can confirm that both Gabriel and Victor are likely to depart. I’ve expected it for a long time.
“They are working very seriously and we’re working currently with the players who are currently here who are likely to replace them and obviously on future players who will come to us to replace them in their posts,” Galtier said according to Goal.
