The Arsenal legend claims there are no jobs here due to a racist attitude towards black coaches.
He claims football chiefs will not give black people a shot at the big time because of their “archaic” outlook.
The defender also blasted the Football Association for abandoning him and snubbing him for a coaching role.
Campbell, 39, who is studying for his coaching badges, said: “I want to start abroad. There are no opportunities for me here – not until attitudes change.
“We have to ask why there aren’t more black managers and why the likes of Brian Deane (who is working in Norway) need to go abroad to get a chance. I have spoken to other black players and they feel the same – that the attitudes here are archaic.”
