PSG can clinch their 10th league title with maximum points against Lens on Saturday night, although Mbappe's future will remain a topic of discussion.
The French forward's contract expires at the end of the season, with Real Madrid reportedly looking to secure his signature on a free transfer.
"You have to understand it. This does not only happen in Paris, but also in other clubs.
"This is not the first, nor the last time that such situations arise. We have to adapt. Selfishly, I would like to keep Kylian with me, of course. I would like to take him on vacation, take him home, keep him all the time. The club would like him to be able to stay here for a long time.
"It's a negotiation. This decision is always related to different parties. It may be taken once the objective of the title is reached, once the season is over."
