The attacking player, who has been at Lyon since 2011, has been linked with a move to Arsenal.
Bernes has not alluded to where Fekir could potentially be heading, but he has opened the door to a transfer when the window reopens in the summer.
"Will Fekir still be at Lyon next season? It's too early to talk about it," Bernes told Telefoot. "After considering my relationship with [club president] Jean-Michel Aulas, we will make the best decision.
"We have time, that's the straight line. There are important goals and he is already in a big club."
Fekir has scored 16 goals and created six assists in 23 Ligue 1 appearances this season.
