The 23-year-old Ivory Coast international has impressed in Ligue 1 and can operate at right-back or in central defence.
Doue remains under contract with Strasbourg until 2029 and is reportedly valued at around €40m.
According to journalist Sacha Tavolieri, PSG have already held preliminary discussions with the player’s representatives about a potential transfer.
However, no formal agreement has been reached at this stage. Bayer Leverkusen are also reportedly interested and have identified the defender as a priority target for their right flank.
A move to Paris would see Doue reunite with his younger brother Desire, who joined PSG in 2024.
