"We always said we're planting the flag of Fermanagh on the 21-yard line in front of goals and no man gets that flag."

Complacency should be a major concern for Dublin on Sunday, warns former Fermanagh manager Charlie Mulgrew.

Former Donegal player Mulgrew was the last manager to guide the Erne County to Croke Park in the championship and believes Dublin could be caught out if they find the going too easy for them without showing that superiority on the scoreboard.

"No team in Ireland can stop Dublin when they get rolling but they have shown they can be a wee bit flawed in their mentality and they can be caught," said Mulgrew, referring to last year’s All-Ireland semi-final defeat to Donegal.
