Atletico Madrid president Enrique Cerezo admits Chelsea's price for Thibaut Courtois is too rich for them.
Atletico would like to convert the Belgian's loan into a permanent deal.
"Courtois is incredible on the pitch. We are interested but the price is too much for a keeper," said Cerezo, quoted in the Daily Mirror.
"We want to try to do business, but it depends on Chelsea. We must study everything.
"For me, it is clear that Courtois is the best goalkeeper in Europe."
