Always said that Celtic was the wrong move for Turnbull from a development point of view but, at the same time, can just about understand why he went.
I wonder what he must think when he sees someone like Lewis Ferguson who, IMO, Turnbull was a better player than he was with us and Ferguson was at Aberdeen. As it is, Ferguson is in Serie A captaining a Bologna side who are challenging for Europe whereas Turnbull is staring down the barrel of a move to some mid table Championship jobbers.
