The Checkered Ones miraculously overcame Brazil on penalties to make the final four for the second time in a row, and goalkeeper Dominik Livakovic was the hero of the hour once more.
The Dinamo Zagreb man made 11 saves before keeping out Rodrygo's penalty, and he will now face the unenviable task of trying to quell the Lionel Messi-led Argentina attack.
Aiding him will be the centre-back pairing of Josko Gvardiol and Dejan Lovren, both of whom have excelled for a Croatia side who have only shipped three goals at the tournament so far.
Josip Juranovic will continue on the right, and Borna Sosa should be fit enough to take his rightful place on the left after overcoming an illness to displace Borna Barisic last time out.
Luka Modric, Mateo Kovacic and Marcelo Brozovic are immovable in the midfield trident, as is Ivan Perisic in the final third, but Dalic is still pondering one or two selection queries.
Bruno Petkovic came off the bench to hit a late leveller in extra time against Brazil and could now challenge Andrej Kramaric, but the ever-present Hoffenheim man will still expect to get the nod alongside Mario Pasalic.
Croatia possible starting lineup: Livakovic; Juranovic, Gvardiol, Lovren, Sosa; Modric, Brozovic, Kovacic; Pasalic, Kramaric, Perisic
