Ireland will try to shake off its underdog moniker and cause an upset at the European Championship, inspired by Chelsea's surprise Champions League triumph.

Chelsea overcame the odds in beating Barcelona and Bayern Munich on the way to victory in Europe's premier club competition. Ireland's tough group draw at Euro 2012, including reigning champion Spain and 2006 World Cup winner Italy, means the team is also an outside bet.

But Ireland coach Giovanni Trapattoni said Saturday that Chelsea's win in Munich shows you can ''never say never''.

The 73-year-old Italian was even confident enough to name his starting lineup for Sunday's opening Group C match against Croatia in Poznan.

Ireland will play Spain on June 14 and Italy on June 18.
