Italy CT Roberto Mancini tried out a front three of Federico Chiesa, Ciro Immobile and Federico Bernardeschi in training on Monday.
ANSA reports Mancini went with Gianluigi Donnarumma in goal and a back four of Alessandro Florenzi, Leonardo Bonucci, Giorgio Chiellini and Cristiano Biraghi.
A three-man midfield of Nicolo Barella, Jorginho and Marco Verratti would then have supported a Chiesa-Immobile-Bernardeschi trident up top.
The agency adds Cristiano Piccini, Vincenzo Grifo and Fabio Quagliarella were also trialled, while Nicolo Zaniolo, Leonardo Pavoletti and Kevin Lasagna did individual work.
The Azzurri kick off their Euro 2020 qualifying campaign against Finland on Saturday, prior to facing Liechtenstein next Tuesday.
