Dublin will be aiming to become just the third county to claim four All-Ireland Senior Football titles in a row this afternoon.
Standing in their way is a Tyrone side who have reached the decider for the first time since 2008.
Ahead of the encounter, Dubs defender Jonny Cooper believes the team as a whole have worked hard to be able to cover potential mistakes made during a game:
Jim Gavin has named an unchanged side for the clash, which means Cian O'Sullivan has been passed fit to start.
Meanwhile Tyrone manager Mickey Harte has brought Mark Bradley into the full-forward line in place of Lee Brennan.
Harte admits his players have a big challenge ahead of them to de-throne Dublin.
Speaking to WLR Sport, former Wexford and Kildare boss, Waterford man Jason Ryan feels that Dublin's big match experience could prove the difference.
He believes that Ciarán Kilkenny is the front runner for footballer of the year at the moment.
Throw-in at Croke Park is at 3:30.
In today's curtain raiser at GAA HQ, Kerry will be aiming for their 5th All-Ireland Minor Football title.
They face Galway in today's decider, with throw-in at 1 pm.
