Juventus defender Giorgio Chiellini can handle a change of system with Italy for their crucial Euros clash with the Republic of Ireland.
Cesare Prandelli tested out the 4-3-1-2 system in training, scrapping the 3-5-2 that has been used so far in the competition.
"It's all the same for me. In previous years I almost always played in a four-man defence, while it's not even necessarily three at the back throughout this season," said the Juventus man.
"I have had a long career and we've all played in various systems, so we have shown our versatility. The important thing is to remain balanced.
"I've already played with most of my teammates and we've been training for a month to ensure we're all on the same page. When that is the case, it gives you an advantage in any tactical approach."
