Real Sociedad fullback Yuri Berchiche is on his way to PSG.
Marca says PSG are seeking an agreement to bring Berchiche to Ligue 1 from Real Sociedad, with Maxwell stepping into retirement.
A deal is yet to be agreed between the clubs.
The LaLiga side have asked for 30 million euros in exchange for their man, while PSG are currently offering just 15m euros.
