Premiership clubs are on red alert over reports Sol Campbell is set to be released by Notts County.

The Daily Mail says County are set to grant Campbell's wish and have agreed to release him from the £40,000-a-week deal he signed.

Campbell had expected to undertake some coaching duties at the club but will be in great demand as a player again because he will be a free transfer.

Newcastle were interested in signing him during the summer and, with a takeover finally seeming likely at St James' Park, may well target him again.

Tottenham manager Harry Redknapp has described him as one of the top six defenders in the Premier League and would have signed him if it were not for his history with the club.
