Released Notts County defender Sol Campbell has four clubs chasing his signature.

The Daily Mail says Aston Villa, Wolves, Hull and Newcastle are monitoring Campbell's situation after the Premier League said they would look into his appeal to allow him to join a team before the January transfer window opens.

Under Fifa rules, the 35-year-old is barred from signing for another club after walking out on Notts County.

Campbell, who has received backing from PFA chief executive Gordon Taylor, will need to prove he had just cause for leaving County just 29 days into his five-year deal .
