Barcelona are believed to be showing considerable interest in Chelsea goalkeeper Thibaut Courtois.
The 20-year old Belgian is again impressing on his second season-long loan with Atletico Madrid with the The Sun suggesting his performances have not gone unnoticed by the Catalan giants.
Barcelona are preparing to bring in a future replacement for Victor Valdes with sources close to Courtois saying they have enquired about his availability 'without making a formal offer.'
