The former Villa and Manchester United striker is said to favour a move to Blues in preference of moving north-of-the-border to Celtic. "He fancies Birmingham as he still has friends around following his time at Aston Villa. "I liked him as a man, but I thought I should have got more from him. "I would only wish him well for the future."
Rovers boss Graeme Souness told Sky Sports News: "As I understand it, Celtic did agree a fee with us for Dwight and he was given permission to talk to them.
"Now Birmingham have come along and offered the same money, so it is now up to him.
