Atletico Madrid president Enrique Cerezo has said that Chelsea's valuation of goalkeeper Thibaut Courtois is out of reach for the Spanish club.
The 21-year-old, who is midway through his third loan spell with the club, recently admitted that he wanted his future resolved by March at the latest.
Despite claiming that Courtois is the "best goalkeeper in Europe", Cerezo believes that his valuation of £20m is too high.
"Courtois is incredible on the pitch. We are interested but the price is too much for a keeper. We want to try to do business, but it depends on Chelsea. We must study everything," Cerezo told reporters.
"For me, it is clear that Courtois is the best goalkeeper in Europe."
Courtois moved from Genk to Chelsea in 2011, but then joined Atletico on loan.
