Sheffield United have reiterated that Middlesbrough target James Beattie is not for sale, following renewed speculation about his future.
He has been linked with a January move to Boro, but Blades chairman Terry Robinson insists the former England international is not for sale.
Robinson told BBC Radio Sheffield: "I can confirm that there is no get-out clause in his contract, and the only way in which James Beattie is leaving Bramall Lane in the January transfer window is if Manchester United come in with a £20m bid!"
