Gordon Strachan has had two bids rejected already for the highly rated 20 year old.
He told the club’s official website: “I consider Craig to be like a son with respect to the way we try and nurture him and I understand he wants to leave and go to a Championship club.
“The fact is our valuation of Craig hasn’t been met by any club and it will be Middlesbrough’s loss when he goes and signs for another club that will meet Rochdale AFC’s valuation.”
