Costello: 'The two games we could have gotten something out of and ultimately we didn't'

So far this season, they've lost both their games back in Division 1, to Monaghan and Mayo but, again, is anyone drawing a straight line between that and their Sam Maguire Cup credentials? Probably not.

So have Dublin shattered the myth that you need to be a Division 1 team, and preferably a high functioning one, to win the All-Ireland?

Last year's spell in Division 2 - they just about beat Kildare and Cork and scraped past Clare at Croke Park - clearly didn't count for much when it came to the meaty end of the Championship.
