The 20-year-old has made five league appearances this season and is regarded by Brest as a prospect for the future.
Le Guen came through Brest’s academy after joining from Châteaulin FC at the age of 13. He moved up through the club’s age groups each season and, during the 2025-26 campaign, gained experience in Championnat National 2, France’s fifth tier, before making the step into the senior side.
Standing at 1.96 metres, Le Guen has developed into a centre-back noted for his physical presence and aerial ability. He was originally a forward before coach Marzin moved him into defence, making use of his height and strength in duels. His development has continued with Brest, where he has become a regular option under the coaching staff.
The defender is under contract until 2029, giving Brest a strong position should interest from Italy develop into a formal approach. Transfermarkt values him at around €15 million, although that figure is an estimate rather than a confirmed asking price.
Le Guen’s immediate priority is recovering from an injury sustained on 24 September. His return date has not been established.
Tuttomercatoweb reports Milan’s interest in the young defender, but there is no indication in the supplied material that the Italian club has made a formal offer. Any potential deal would also have to account for Brest’s long contract and the player’s recovery timetable.
For AC Milan, the appeal lies in the prospect of recruiting a young defender with room to develop rather than a player already at the peak of his career. His height gives him an obvious physical advantage, while his rapid progression through Brest’s system suggests the club believes he can continue improving.
A move would depend on Brest’s willingness to negotiate and whether Milan decides to turn its reported interest into a concrete approach. The club’s decision to tie him down until 2029 underlines how highly it rates a player who has advanced quickly from youth football to senior competition.
