I still find Luca Modric on the squad, He is 35 old year which I think is not good again to run to get the ball. better to put him on the front together with Mandzukic. but the formation I look, Modric will play as playmaker to supply a ball to front. so when meet Maroco where have Ziyech and Hakimi, there will be surprise if draw. We have to forget Croatia as finalist long time ago because they have the old player inside.
Luka Modric still plays good even though he is 35 years old. He is playing as a playmaker and he is still Croatia's best midfielder. The team doesn't look the same with him in the team or without him.
You mentioning Mandzukic shows that you have no idea about Croatian team. Mandukic stopped playing for Croatian team after they finished at the second place in Russia four years ago.
