Manchester United are growing concerned that David De Gea might have played his last game for the club, sources have told ESPN.

United chiefs believed they were close to an agreement with the goalkeeper to extend his contract but talks have dragged on and there are fears he could now leave this summer.

Sources have told ESPN that the club decided against triggering a one-year extension to De Gea's contract, which would have kept him at the club until 2024. The option expired in May.

Instead, negotiations have taken place about a longer deal on a lower basic wage but including significant performance-related bonuses.
