This summer's transfer window will mark an important juncture in Manchester United's future.

Not only does uncertainty continue to surround manager Erik ten Hag's future, the squad is also at risk of being shaken up by Sir Jim Ratcliffe and the Ineos Group. As reported by the Manchester Evening News last month, a record number of player sales are planned, with United aiming to become more proactive in the seller's market.

The club also intends to be active on arrivals, with a handful of positions having been identified as areas to strengthen. It means big changes to the landscape of the squad are poised to be made.

With that in mind, MEN Sport brings you a detailed guide on when each United first-team player's contract expires.
