Chelsea youngster Thibaut Courtois, who has spent the last two-and-a-bit seasons on loan at Atletico Madrid, believes he is already among the world's five best goalkeepers.
The 21-year-old has not played a single match for Chelsea, despite arriving at Stamford Bridge from Genk in 2011.
However, Courtois has since cemented his reputation as one of the best young goalkeepers in Europe during his loan spells at the Vicente Calderon.
The Belgium international disagrees with this assessment slightly, because he believes he is one of the best goalkeepers - of any age group - in the world right now.
"I am in my best form. And I feel that I am among the five best goalkeepers in the world," Courtois told AS. "I've grown a lot at Atletico, especially last season when we won the European Super Cup and the Copa del Rey.
"I've made great progress, especially in terms of speed, reflexes and experience.
"I want to play, I will not be sitting on the bench. At Atletico I feel great and it allows me to play in the Champions League."
These comments indicate that Courtois will not return to Stamford Bridge next season simply to play second-fiddle to Chelsea's current first-choice goalkeeper Petr Cech, who turned 31 in May.
Blues' boss Jose Mourinho, therefore, will need to make a difficult decision next summer: either use Courtois as his main 'keeper, or risk losing the young Belgian to another club.
