Richard Dunne says he cannot wait to make up for lost time as he prepares to taste major tournament action for the first time.
The 32-year-old was part of the Republic of Ireland squad for the 2002 World Cup, but did not feature as Mick McCarthy's men came within a whisker of the quarter-finals.
At Euro 2012, they face a tough challenge in a group that includes Italy and holders Spain and the Aston Villa defender said: "I can't wait. They are the biggest games of all of our lives, probably. I am really confident about how strong we are and if things go our way as far as luck is, we can definitely give everyone a test."
