PSG chief Leonardo is monitoring Kepa Arrizabalaga's situation at Chelsea.
Okdiario says Leonardo is having doubts about Keylor Navas for next season and is looking around for a replacement.
Kepa is on the Brazilian's shortlist, with the PSG director well aware of his problems this season at Chelsea.
Despite tension with manager Frank Lampard, Kepa remains highy regarded across Europe, particularly over the way he has overtaken Manchester United goalkeeper David de Gea as Spain's No1.
Should Leonardo firm up his interest, PSG would expect a healthy discount on the world record €80m Chelsea paid Athletic Bilbao for the keeper two years ago.
