The national team boss is looking forward to the match in Liege and says his side can now play the way he wants following their group stage exit at the 2010 World Cup
Prandelli's men are in good form following Friday's 3-1 win over Estonia in a Euro 2012 qualifier, and while there are several changes to the starting XI, the boss hopes to see the good work continue.
"I cannot wait to play the friendly games ahead of us [Ireland and then Spain in August], these are tests that can make us take the step up in quality," he told Rai Sport.
"They are exams that can show us the real dimension of this group. As a national team we have rediscovered the serenity [after the 2010 World Cup].
"Now this Italy can play in the way I want."
The expected Italy starting XI for the game against Ireland is as follows:
Emiliano Viviano; Mattia Cassani, Alessandro Gamberini, Giorgio Chiellini, Domenico Criscito; Andrea Pirlo, Antonio Nocerino, Claudio Marchisio; Riccardo Montolivo; Giuseppe Rossi, Giampaolo Pazzini.
