According to The Daily Mail, Wolves have rejected a £1m bid from Sunderland for central defender Dion Sanderson.

The Lowdown: Sanderson impresses on loan with Black Cats

Sanderson spent last season on loan at the Stadium of Light, and impressed at the heart of the back four, so much so that Wolves fans were desperate to bring the youngster back when the season ended.

As such, the Black Cats want to see him return to the club permanently ahead of next term.

The Latest: Sunderland make Sanderson bid

Now, it has been reported that the north-east outfit have made a bid of £1m for the 21-year-old.

Wolves, though, swiftly rejected the offer - they are looking for a fee of £2m for the defender.

Sheffield United are also interested, but are yet to make a concrete approach.

The Verdict: Top target

There is no doubt Sanderson should be a top target for Lee Johnson and co. Of the 26 matches he played some part in last term in League One, the Black Cats lost just four (absence through to injury.

Johnson even called him a "Rolls-Royce" earlier this year (The Chronicle Live).

He proved himself to be an important player for Johnson throughout the campaign and, as Sunderland aim to earn promotion to the Championship, the signature of Sanderson could prove to be key. It remains to be seen whether the club can get their man this summer.

In other news, Sunderland hope to sign this in-demand winger.
