Sheffield United have been stunned by Manchester United demands over a new season-long loan for Dean Henderson.

The Sun says as the England hopeful closes in on a new £100,000-a-week contract at Old Trafford — despite interest from Chelsea — that is causing problems for Chris Wilder’s side.

Blades have paid a chunk of the goalkeeper’s contract over the past two seasons — but that was a lot less than his new terms.

The Red Devils may be willing to send Henderson out on loan again next season but want his bumper salary covered.

Old Trafford chiefs are comfortable offering 23-year-old Henderson a lucrative, long-term deal to keep him happy.

But they are now talking tough when it comes to loan deals for him.
