Campbell is free to join a new club in January after having settled his contractual dispute with Notts County, who he left just one game into a five-year deal.
Campbell has been linked with a move to Newcastle in recent months.
“The paperwork is now with Notts County, an agreement has been reached, but as yet they haven’t signed the documents and sent them off to the Football League. I am waiting for that to happen,” said Campbell.
“My guess is that it will somehow coincide with the opening of the transfer window, and I will be free to play in about three weeks’ time.
“Where I am going to play? Well, that is interesting. I have a few clubs tabling offers at the moment, but one of them doesn’t seem to be Newcastle now.”
