Sheffield United have set their sights on Wolves defender Dion Sanderson amid his impressive Sunderland loan, Football Insider understands.

The 21-year-old has been described by Black Cats manager Lee Johnson as an “absolute Rolls Royce” on the back of his displays this season.

A recruitment source has told Football Insider that Sheffield United have been alerted to Sanderson’s performances and have started keeping tabs on him ahead of the summer.

The Premier League club’s talent spotters watched Sanderson in action in Sunderland’s recent 2-1 defeat to Shrewsbury Town.

He was the only defender in Johnson’s side to emerge with any credit in Saturday’s 2-2 draw against Crewe Alexandra.

That was the youngster’s 17th appearance of the season for Sunderland.

That has included nine league starts, the majority of which have come since December and in the absence of the injured Bailey Wright.

Sunderland beat a number of EFL clubs to Sanderson’s signature last summer including Championship big guns Swansea City and Cardiff City.

Wolves opted to loan him out again following his spell at Cardiff last season as appearances at Molineux were likely to be limited.

The promising defender, who made his first-team debut in 2019 in a League Cup game against Aston Villa, is highly thought of at Wolves.

But they might be open to a summer deal as he has yet to add to that single senior appearance.
