Republic of Ireland defender Shane Duffy ruled out talk of a Danish revenge mission, but insisted his team-mates have full belief they can win in Copenhagen on Friday night. 

Mick McCarthy brings his side to the Parken Stadium in search of a third win from three Euro 2020 Group D qualifiers. Ireland have drawn three of their last four clashes with the Danes but it's the 5-1 World Cup play-off hammering at the Aviva Stadium that most fans will reference when this fixture comes around. 

Duffy actually opened the scoring that night before the visitors ran riot and, though he admitted the loss was hugely painful, the Derry man insisted there's confidence in the Irish camp.

"I'm not sure it's revenge," he said.

"We're all professionals. You sort of have to forget about the past and that's the mentality we'll have. It's a fresh start, obviously with the new manager coming in with different ideas. We've got to go there and try to beat them. We're all excited for it.

"We'd had a bad result against them here in Dublin which was one of the toughest nights of most of our careers. We all know it's a huge game now. I don't know if it's revenge but we want to go to the Euros, they're in front of us and we want to beat whoever is in front of us. 

"We've got to go there with a winning mentality. We've got to go there and put it on them, try to win the game. We know their strengths... hopefully we can put them under a bit of pressure and see how it goes.

"We're a lot closer than people think. The 5-1 game probably was the only one we were outclassed, outplayed on the night. But we have top players in this team as well. We've got that bond that maybe other countries don't have.

"We believe in this squad that we are a lot closer and we can beat them on the night. As long as we believe that in the dressing room that's the most important thing."

The Danes' star man Christian Eriksen comes into this one off the back of a major disappointment in the Champions League final. Eriksen - who tore Ireland to shred in that World Cup play-off - was on the Spurs team turned over 2-0 by Liverpool, and Duffy expects the playmaker to be hungry for a win to ease the pain.

"Eriksen is a top player. He can be dangerous whenever he wants. He's a big player for Denmark so he won't want to let his team-mates and his country down. I'm sure he'll be up for it." 

It's been a long campaign for Duffy, who helped Brighton and Hove Albion avoid relegation but saw boss Chris Hughton get the axe nonetheless.

Ireland headed for a training camp in Portugal at the end of May to freshen up 

"We didn't really have that long off. The majority of the team has played a lot of football this season. I know it's a big break between the last game but we had a game against the Under-21s. 

"We know they are a good team. We've given them a bit of respect when we've played, tried to keep it tight and see if we can get them on the counter. Hopefully we'll have a different idea now, don't let them have time on the ball to play how they want to play. I'm sure Mick will be having his ideas; he's been doing it already in training."
