Chelsea are under growing concern that goalkeeper Thibaut Courtois could push for a summer transfer away from the club, report Football Insider.
The Belgian ‘keeper is the man the club have tasked to replace Blues legend Petr Cech between the sticks, having left for Arsenal once he was demoted to an understudy role.
He spent three years on loan with Atletico Madrid during his formative footballing years and has emerged as one of the best stoppers around.
However, the nightmare season the Stamford Bridge club have been through means they are highly unlikely to qualify for the Champions League next year.
As a result, they are reportedly worried the 23-year old will become a major target for other top European clubs.
Despite his success with city rivals Atletico, Real Madrid have previously been linked with a move for the custodian.
Amid one of the worst seasons for the West London giants in recent memory, Courtois has kept his stock relatively high and is considered one of the best ‘keepers in Europe.
