It has been 20 years since Donegal last claimed the Sam Maguire and now Mayo - who were surprise winners over Dublin in the semi-finals - stand in their way.

Jim McGuinness has named an unchanged side for the showpiece clash at Croke Park, and he has told UTV he believes his team have what it takes to get over the line on Sunday.

He said: "Obviously the 1992 team achieved something that no-one else has done, and nobody can ever take it away from them, and anybody who wins an All Ireland is the same.

"That is pretty much what I wish for this group of players.

"If they can get over the line on All Ireland final day that is a big milestone in their life as a footballer and as a person as well.

"They have worked very hard for this opportunity, particularly in the last couple of years they have really put their head down and the game really presents itself now for them and my hope now is that they can take that opportunity."

Meanwhile team captain Michael Murphy believes the Ulster Championship winning side have proved their credentials this season and can go all the way.

"It's been a hell of a journey this year coming through Ulster, which is always a minefield," he said.

"Any team that wins an Ulster Championship you would say is deserving because any of nine counties can go out and win it and we are delighted to retain it this year.

"Going in facing Kerry, which people look at as one of the best sides in the country over the last number of years, and the last outing against Cork, we are grateful to manage to get into a final.

"When the final whistle was blown, a sense of relief starts away when the final whistle was blown, that turned to joy."

Donegal's assistant manager Rory Kavanagh is a Fermanagh man, but he knows how much it means to the players to be in the final after the disappointment of last year.

He said: "You can understand the nerves but it is something that has to be enjoyed.

"It is a huge occasion for them it doesn't change anything, it's another game of football that has to be won and at this stage it's all about winning.

"That's the proposition that lies ahead of us now, the Mayo side will be full of confidence and they will be going all guns blazing. They have a very strong defence and massive men around midfield and the sharp shooters up front that can really punish you so we are going to need to improve all aspects of our game to compete with them."

The game kicks off at 3.30pm on Sunday.

It will be shown on the big screen in the grounds of City Hall in Belfast, with free admission on a first come first served basis.

The council said: "Respective team jerseys and flags will be allowed, although flag poles will not. Picnics are welcome, but no alcohol will be allowed on site."
