Fermanagh manager Pete McGrath is prepared for a pressure cooker atmosphere in Ballybofey on Sunday - but insists his team have exactly what it takes to escape with a precious championship victory.

The Erne men eased past Antrim to set up an Ulster SFC quarter-final showdown with Donegal this weekend as they look to emulate their run to the All-Ireland quarter-finals last summer. 

McGrath said there's huge respect for Donegal in the Fermanagh camp, but is rallying his troops for a huge effort against Rory Gallagher's men.

"We're under no illusion about the extent of the task that we face, but we also believe that if our performance on Sunday is somewhere near our optimum then we will be very close," he told RTÉ Sport.

"We go to Donegal with every respect for what they've done in recent times but we go totally believing in our ability to get the result that we're after.

"To beat Donegal, to compete with them you have to show the same energy that they do, you have to show intent. You have to show a lot of character.

"We are moving in the right direction. Every major game is an opportunity for us to learn."

"Ballybofey will be a cauldron on Sunday. It will be a match that will test us in terms of our temperament, in terms of our ability to deal with pressure situations, and I suppose that's what championship football is all about.

"It will be a pressure cooker environment and if we're able to survive in that and thrive in that and perform in that to the way we're capable of performing then I think we're in with a very very healthy chance of winning this game."

Fermanagh's summer adventure was ended by eventual champions Dublin in Croke Park last August.

They won many admirers en route to that 2-23 to 2-15 defeat, and McGrath believes the experience they gleaned on that run wil stand to them massively this year.

"When any team is working hard and the players have got ambitions and they're coming from let's say a relatively low base, then whatever progress you get has to be factored into the mindset," he added. 

"Winning and playing on big days is what gives players real belief and a sense of their own worth and their capability of competing with the top teams.

"We are moving in the right direction. Every major game is an opportunity for us to learn, but also an opportunity for us to go out and win that game and make a big statement. That's what Sunday's game is all about. It's going to be a massive test but it's one that we are relishing."
