The 37-year-old, who came through the youth ranks at Bramall Lane, will end his third spell at the club at the conclusion of his current contract, departing having made 377 appearances and scored 129 goals.

He did play 45 times for the Blades last season as they won promotion from the Championship and reached the semi-finals of the FA Cup, but boss Paul Heckingbottom does not think he is worth a new deal in the top flight.

Jack O’Connell and Enda Stevens are also released and will depart the club having played their parts in promotions over the years.

The Blades have exercised the options on contracts for Oliver Norwood, Oliver McBurnie, Wes Foderingham and Ismaila Coulibaly to keep them at the club while negotiations over new deals for John Fleck, Jack Robinson and Ben Osborn are ongoing.
