GARY CALDWELL
A very divisive figure among Celtic fans, very definitely a Gordon Strachan signing.
It was a sign of spending being reigned in but as Bobo Balde was pushed into exile Caldwell was twice involved in the knock out stage of the Champions League.
He made 150 appearances in total before Tony Mowbray opted to sell him to Wigan, Caldwell had a strong opinion of himself that many supporters just couldn’t handle.
