L'Équipe confirmed that conversations between the player's representatives and PSG over a new deal are expected to begin imminently, with the French champions keen to tie down a talent they regard as one of the most promising forwards to emerge from their academy in recent years.
Mounguengue made his senior debut for PSG in the first week of May, coming on as a substitute in a Ligue 1 fixture and immediately catching attention with his movement and composure.
The club had protected his development carefully before giving him that first opportunity, and the decision to start extension talks now is a clear signal of how highly he is regarded internally.
Bayern Munich's interest in the 18-year-old adds a significant dimension. The German champions have been active in identifying teenage talent across Europe and view Mounguengue as a player who could develop into a senior asset over the next two to three years. Paris FC, currently competing in Ligue 2 after their promotion campaign fell short, are also understood to have made an approach.
PSG are confident they can retain Mounguengue but are aware that interest from a club of Bayern's stature will need to be addressed rather than dismissed. Whether the player's camp views a contract extension as the right path or prefers to let his situation develop over the summer remains to be seen.
