Mourinho reportedly willing to sell experienced stopper if he has a problem with being number two.
Chelsea are open to the possibility of selling goalkeeper Peter Cech, according the The Telegraph.
Cech joined the Blues for just £7m from French side Rennes in June 2004 and he has since made 479 first-team appearances for the Stamford Bridge club.
The 31-year-old featured in 34 Premier League games this season, keeping 16 clean sheets in the process.
However, he missed Chelsea’s last four games of the campaign after dislocating his shoulder in April.
The injury required surgery and he is unlikely to fully recover from the operation until the middle of July.
That means that Belgian stopper Thibaut Courtois, who is currently on loan at Atletico Madrid, will start pre-season as Chelsea’s first-choice goalkeeper.
The Telegraph claim that Chelsea manager Jose Mourinho will attempt to sell or even loan out Cech if he is unwilling to be Courtois’ understudy.
Courtois, who celebrated his 22nd birthday last week, is currently in his third season as an Atletico loanee.
Atletico will win La Liga if they avoid defeat at Barcelona on Saturday. Seven days later, they take on city rivals Real Madrid in the Champions League final in Lisbon.
