Sharp who scored bags and bags of goals across the Humber for Scunthorpe is wanted by Hull boss Phil Brown.
Brown, who spoke on Radio Humberside today, revealed he had been interested in bringing former City star Fagan back to the KC whilst he had also enquired about Billy Sharp and several other strikers` at Kevin Blackwell's disposal.
Sharp's only goals for the Blades have been the pre-season game against Nottingham Forest where he scored the winner, and to goals against Morcambe in the Carling Cup at Bramall Lane.
