Fold the club? That's utter bollox. It's getting more and more like Twitter on here.
What does it really matter who thinks one club is "bigger" than another...most probably every football fan thinks their club are bigger because their club means more to them than any other. History, past glories, training facilities all mean nothing to the shifting sands of football. If Mansfield do gain promotion and Latics knock them out of the FA Cup next season, it will be considered the metaphorical 'giant killing'.
That's football for you, it's all about the here and now.
