According to Daily Record, Celtic and Rangers are both interested in signing the young striker and they have informed his club that they will hold pre-contract talks with him.
The Stoke City player is out of contract in the summer and it would be a superb bit of business if Celtic or Rangers manage to sign him on a free transfer then.
Campbell’s suitors will have to pay around £400,000 in training compensation if they sign him.
For a player of his talent, that would be a major bargain.
Both Celtic and Rangers can afford him and they need someone like him as well.
