"When I was there we had a team full of tough guys. All great gentlemen, straight-talking. There were loads of characters, great banter and with that came a few fights from time to time. But above all that, it was a team full of great personalities; great people.

"It was extremely tough when we were playing; I don't know whether things have softened now. Has life softened? Regardless, you still need those players with that fight inside of them who can go away to Burnley on a windy midweek night and get a result."
