So Italy v Croatia.
Italy's Andrea Barzagli is not ready to return so Daniele De Rossi will continue as a makeshift centre-back.
Azzurri coach Cesare Prandelli may drop Mario Balotelli in favour of Antonio Di Natale, who scored as a substitute against Spain on Sunday.
Croatia boss Slaven Bilic selected an attacking line-up against Ireland, and could pick a more conservative side.
One option would be to switch right-back Darijo Srna to the right wing, a position he often filled in qualifying.MATCH PREVIEW
