Sol Campbell has revealed Newcastle are one of the clubs keen on him.
The former England defender left Notts County after just one appearance, and will be available to move on when the League Two side agree to release his registration, which is the subject of ongoing negotiation.
The 35-year-old believes joining Newcastle could allow him to play a part in a promotion campaign before returning to the Premier League, where he has previously played for Tottenham, Arsenal and Portsmouth.
Campbell told ESPN Soccernet: "I have been approached by several clubs, and yes, it is correct to say that Newcastle are one of them.
"People might be surprised to hear me say that I would be very interested in a move there, but I have my reasons. Also, Newcastle are a big club and could be heading back to the Premier League. It appeals."
