Fermanagh’s Eoin Donnelly says they can’t rely on another late late show against Donegal in Sunday’s Ulster final.
The Ernesiders qualified for their first provincial decider in 10 years after a stoppage time goal against Monaghan in the semi-final.
Now Donegal stand in the way of Rory Gallagher’s men and their first Anglo-Celt Cup.
Donnelly, who scored the vital goal in the 1-08 to 0-10 win, told RTÉ Sport: "We can’t leave it that we’re a couple of points down going into injury time like we were against Monaghan.
"We have to score more, we have to be ahead. We have to be better in our attacking play and that’s something that’s a challenge for us to get right.
"Yes [we can win]. It’s going to take a massive amount of hard work.
"It’s going to take a lot of effort from everyone all over the pitch; we are going to have to defend better than we have before.
"Donegal have got scorers all over the place, they’ve got young fellows that have come in to add to the experienced fellows.
"We know we’ll have to defend as well as we ever have but we have to score more than we have done in the past."
The midfielder also recalled his own intervention in the semi-final, the last-gasp winner.
The captain said: "Rory sent me into the square. I was probably out on my feet out in the middle of the field.
"Big Tommy [Clarke] came on and they put me in.
"The ball came in and I heard the keeper coming for it and I knew I was in the right area and was able to get a good flick on it and a good connection.
"When I hit the ground I seen the ball in the back of the net and I knew it had landed in the right area."
