Marc Cunningham has recovered from a shoulder problem

Marc has lost both his parents in the three years that he has been part of this Tyrone minor football squad.

Watching Marc giving interviews at Tyrone's pre-final press night, a well-known GAA figure in the county talks of his "remarkable resilience".

As another remarks:"Killeeshill must be proud of this lad."

His own talent is immense but Marc prefers to talk about the people who have helped him along the way in his football career.

"It would be good to win it for the ones at home who started me off as a young cub in the club," he says.

"Then when I went to school (St Ciaran's Ballygawley), Mickey Harte and Martin McElkennon were there to train me and bring me on that bit more."

Before we know it, it will be all over and you don't want an All-Ireland Final to pass you by Marc Cunningham

On Sunday, Marc is hoping to follow Kevin Hughes in bringing honour to his club by claiming an All-Ireland medal.

Hughes helped Tyrone claim the Sam Maguire Cup last year by producing a man-of-the-match display in the senior decider against Armagh.

Going into Sunday's final, Marc's main emotion is relief that he's actually going to be fit enough to play.

A shoulder injury ruled him out of the All-Ireland Semi-Final win over Down which was a re-match of the Ulster decider won six weeks earlier by the Red Hand County.

"Fitness wise, everything seems to be OK now.

"I've got a few tough sessions under my belt and I feel that all the lads have helped to bring me on and get me up to their level of fitness."

However in the Croke Park dressing-room shortly before the throw-in on Sunday, the final words of inspiration will be delivered by Marc.

"I won't have any speech prepared but it will be whatever I think will get the team going and revved up.

On a big day like an All-Ireland final, a few men could collapse Marc Cunningham

"It's good to get the boys psyched up and concentrating.

"Before we know it, it will be all over and you don't want an All-Ireland Final to pass you by."

So far in the campaign, substitutions have played a crucial role for Tyrone and Marc says this could well be the case again on Sunday.

"On a big day like an All-Ireland final, a few men could collapse but we've got a strong panel of boys that we can bring on from the sideline as has been shown already this year."

Whatever happens on Sunday, Marc says there will always be a "special bond" between this group for the rest of their lives.

"We're always texting each other outside training and going swimming together and things like that.
