Italy have tested out a 4-3-1-2 system for Friday's Euro 2012 qualifier against Estonia, but will Sebastian Giovinco or Alberto Aquilani start?
Cesare Prandelli continued his training sessions at the Coverciano camp ahead of the Friday evening match in Modena.
Once again, the system adopted was 4-3-1-2, although the names of the starting XI remain uncertain.
Christian Maggio, Andrea Ranocchia, Giorgio Chiellini and Federico Balzaretti made up the defence.
In attack, Giuseppe Rossi is the hot favourite after scoring a hat-trick in yesterday's game with the Under-18 side.
The Villarreal talent should be partnered by Giampaolo Pazzini of Inter.
In the role of trequartista, Parma starlet Giovinco is battling the more solid option Aquilani.
As for the midfield, Andrea Pirlo was again used in front of the defence with Riccardo Montolivo and Antonio Nocerino, although Claudio Marchisio could be picked instead of the Palermo man.
Prandelli and assistant manager Gabriele Pin split the squad into groups to go over specific tactical moves for defence, midfield and attack.
Italy (probable): Buffon; Maggio, Ranocchia, Chiellini, Balzaretti; Nocerino, Pirlo, Montolivo; Giovinco; Rossi, Pazzini
