As per usual, due to their high volume of versatile players and their love for tinkering, it's not easy to figure out what Croatia's lineup looks like. On paper, a 4-3-3 formation looks most likely, though a 4-4-2 with either Luka Modric or Ivan Rakitic on the wing is certainly very possible.
For those hoping to see Eidur Gudjohnsen for Iceland, you're out of luck. He starts on the bench. Iceland are going with a very attacking 4-4-2 at home, starting attacking midfielder Gylfi Sigurdsson in a two-man center, which will put a lot of pressure on Aron Gunnarsson to boss the midfield.
Iceland lineup (4-4-2): Hannes Halldorsson; Ari Skulason, Kari Arnason, Ragnar Sigurdsson, Olafur Skulason; Johann Gudmundsson, Gylfi Sigurdsson, Aron Gunnarsson, Birkir Bjarnason; Kolbeinn Sigthorsson, Alfred Finnbogason
