Italy boss Cesare Prandelli tested 4-3-1-2 and 3-4-3 systems in this morning’s training session ahead of their Euro 2012 opener.
The Azzurri face Spain on Sunday and there is some doubt as to what shape they will use following Friday’s 3-0 friendly loss to Russia.
On one side, the Coach fielded a team with goalkeeper Salvatore Sirigu behind a back-four of Christian Maggio, Leonardo Bonucci, Giorgio Chiellini and Federico Balzaretti.
The midfield consisted of Thiago Motta, Antonio Nocerino and Claudio Marchisio. Alessandro Diamanti was used behind Sebastian Giovinco and Antonio Di Natale.
They faced a team with Gigi Buffon in goal and a back-three of Davide Astori, midfielder Daniele De Rossi and Angelo Ogbonna.
The four in midfield contained Ignazio Abate, Andrea Pirlo, Riccardo Montolivo and Emanuele Giaccherini.
Fabio Borini, Antonio Cassano and Mario Balotelli formed the trident.
A decision will be taken later today on whether Juventus defender Andrea Barzagli is sent home because of injury. Should he be omitted then Cagliari’s Astori will take his place in the official 23-man squad.
