Aston Villa defender has unwavering faith in Giovanni Trapattoni's system and says that Ireland can emerge from a difficult sectionRichard Dunne has said that Ireland must believe in their ability to progress if they are to qualify from their Euro 2012 group.
Ireland have been drawn in Group C with Giovanni Trapattoni's native Italy, Slaven Bilic's Croatia and reigning champions Spain.
Speaking to BBC, the Aston Villa defender said that the spirit in the Irish camp is positive and that there was an atmosphere of togetherness.
"We're a close bunch of friends and the longer we spend together, the better the atmosphere is. We know that when we go into the games [in Group C] we're going to fight for each other," said Dunne.
He continued: "We have to believe we can do a job, and we do believe we can qualify out of our group, otherwise there's no point in being here.
"We know we're as organised as anyone and as strong as anyone, so it's just about hopefully having that little bit of luck that will help us progress."
The Dubliner previously told the Evening Herald, in the aftermath of the victory at home to Bosnia-Herzegovina, that he believed that Ireland's defensive record showed how strong the squad was.
"That's 13 games unbeaten now and a lot of clean sheets and that says a lot about the players," said Dunne.
He added: "But it also says a lot about the manager and how he organises us. The way we play everyone knows what they have to do, no matter who is in the team.
"We have had a lot of changes in the back four over the last while but we keep getting results and it's a long time since anybody beat us. If we keep doing our job, we will be very hard to beat in the finals." concluded the defender.
Ireland open their Euro 2012 campaign on June 10 against Croatia in Poznan.
