I see where you are coming from, but in reality, it is normal to list the biggest clubs. I would expect had we appointed Nicky Butt, we would be reading about former Manchester United legend. And forgot all about Newcastle, Birmingham City and South China.
At the end of the day, his biggest achievements were with Rangers and Scotland, the press and punters up here will most associate him with those two aspects. I don't really see the problem.
All the best McCall. I am yet to be convinced, but will support you until you do something to deserve otherwise!
