Atletico Madrid want to sign permanently on-loan Chelsea goalkeeper Thibaut Courtois.
The Daily Mail says anxious Chelsea bosses despatched goal-keeping coach Christophe Lollichon to Madrid over the weekend to monitor the Belgian's form against Real Betis and talk over his future plans.
Though reluctant to return to Stamford Bridge in an understudy capacity, it is understood the 20-year old has been assured Chelsea see him as long-term successor to Petr Cech.
As they weigh up their next move, Chelsea may consider opening talks over a new improved contract.
