They do have a chance at it but I personally feel it's still a bit difficult.
Croatia has a huge advantage in this regard but even more so given their previous record they still look very strong for Morocco.
In terms of players, it is also clear that Croatia is superior, so this possibility will be an easy win for them.
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.
Not only about Modric but there are still some good players as well like Perisic or maybe Kovavic in tandem with Modric in midfield.
Modric himself is likely to be the last for him to lead his colleagues in the Croatian national team so it is certain that he will not waste the last title for him.
Today they had a friendly match with some of their substitute players and the results were still quite good against Saudi Arabia they won with a narrow score of 1 goal.
