Chelsea are desperate not to lose goalkeeper Thibaut Courtois.

On-loan with Atletico Madrid, Courtois has been priced at £20 million by concerned Chelsea management.

Manchester United spent £18.9m on David de Gea when he joined from Atletico two years ago but, privately, Chelsea feel Courtois is a much better keeper than the Spaniard, says the London Evening Standard.

Chelsea are in an awkward position because Cech signed a contract extension last summer which will see him stay at Stamford Bridge until 2016 and he is enjoying another impressive campaign.

The club see Courtois, whose contract also runs out in 2016, as Cech's long-term replacement but are unsure when they will make the change.
