Thibaut Courtois has joined his team-mate Eden Hazard in casting doubt over his Chelsea future by claiming he has proved at this World Cup that he is worth more than the £200,000-a-week contract the Blues offered.

Like Hazard, Courtois enjoyed a superb World Cup for Belgium, who finished third by beating England, and is waiting to find out whether or not Real Madrid now bid for him.

But unlike Hazard, who Chelsea are desperate to keep, the Blues are prepared to listen to offers for Courtois if they can find an agreement on making Roma’s Alisson Becker his replacement.

Courtois is now in the final 12 months of his Chelsea deal and the last offer the club made to him was a £200,000-a-week contract in December, which they believed at the time he would sign.

But Courtois stalled over committing himself and has now risked upsetting Chelsea further by suggesting the club would need to increase that offer to stand any chance of convincing him to sign a new contract.
