Chelsea goalkeeper Kepa Arrizabalaga is close to joining Real Madrid on loan.
Madrid's regular number one Thibaut Courtois, 31, has suffered a cruciate knee ligament injury and is set to miss the majority of the season.
Ex-Manchester United goalkepeer David de Gea, who is a free agent, had been linked with the Berneabeu but Kepa, 28, has emerged as Madrid's first choice.
Kepa faces competition at Chelsea from Spanish compatriot Robert Sanchez after his £25m switch from Brighton.
Chelsea boss Mauricio Pochettino acknowledged on Friday that there would be "very good competition" between Kepa and Sanchez at Stamford Bridge.
