Belgium international Toby Alderweireld believes Chelsea shot stopper Thibaut Courtois could leave Stamford Bridge in the near future, reports Sky Sports.
Courtois, who is in his third season-long spell at Spanish side Atletico Madrid, is behind Petr Cech in Chelsea's pecking order.
The 21-year-old is yet to start a competitive game for Chelsea since his £7.9m move from Belgium side Genk in July 2011.
Courtois is due to return to Stamford Bridge at the end of the season, however Alderweireld believes his club and international teammate is too good to sit on Chelsea's substitutes' bench.
"He is incredible. He can do everything," said Alderweireld.
"He is good with the ball, he is good with his feet and he is great on his line. I don't think he has a weak point and I think he can be the best keeper in the world.
"I see him in training every day and I see him in games and I doubt there are any keepers better than him.
"He does not want to sit on the bench for eight games then play for one. He is very smart and I think it would be a good choice for him to maybe stay with Atletico, or go to another club where he will be number one."
The Belgium number one has also been labelled 'the best goalkeeper in the world by former Atletico Madrid teammate Radamel Falcao.
Courtois has been in fine form for both Atletico Madrid, where he has played all 13 of their La Liga games, and Belgium, where he has been an ever present in the Red Devils' World Cup qualifying campaign.
