Atletico Madrid boss Diego Simeone is reportedly interested in signing Schalke 04 goalkeeper Ralf Fahrmann at the end of the season.
Thibaut Courtois is the current first-choice shot-stopper at Atletico, but the Belgian international looks set to return to his parent club Chelsea at the end of the season.
According to Bild, the 25-year-old's performances have not gone unnoticed this season, with Atletico just one of a number of clubs who are monitoring developments at the German club.
Fahrmann's current deal expires at the end of next season.
