Sheffield United have failed with a £1.5million bid for Wolves striker Kenny Miller.The Scotland international's contract will expire at the end of the season and he has indicated he will not sign a new deal at Molineux. United, currently second in the Championship, had tried to take advantage of Miller's situation but Wanderers chief executive Jez Moxey revealed the 26-year-old had rejected the opportunity. Moxey told the club's official website: ``We have received a bid of £1.5million from Sheffield United but Kenny told us he was not interested in a move to Bramall Lane. 'We told Sheffield United that we would consider their bid, although it was unlikely to be accepted, but before we started negotiating we agreed we'd ask Kenny for his thoughts - he said no and so the matter went no further.' Miller has been linked with a move back to his previous club, Rangers, who he left to join Wolves for £3million in 2001, and Wolves now face the prospect of losing the player for nothing in the summer unless a club which suits him makes a move during January.
