According to Gazzetta dello sport Zdenek Zeman could present himself at San Siro with an offensive 4-3-3 formation that has three very quick and dangerous forwards. Inter’s Crisetig should play from the first minute whilst Samuele Longo is on the bench. Here’s Cagliari’s probable formation:

CAGLIARI (4-3-3): Cragno; Balzano, Ceppitelli, Rossettini, Avelar; Crisetig, Conti, Ekdal; Ibarbo, Sau, Cossu.
A disposizione: Carboni, Pisano, Capuano, Benedetti, Murru, Capello, Dessena, Donsah, Joao Pedro, Caio Rangel, Longo, Farias.

Note: Daniele Conti wasn’t a part of Zeman’s squad so he won’t play.
