Out of all the players that you mentioned, only Periić and Kramarić will be in Dalić's consideration to call them up for the UEFA Euro 2024. Lovren already announced that he won't be playing for the national team anymore. Modrić said that he wants to see Croatia winning the Nations League, but I think he'll retire from the national team after that. His dream is to bring the gold medal to Croatia so that's his last opportunity. And Vida is out of the question if you ask me. I think that he didn't play at all in Qatar because Dalić found a replacement for him in Gvardiol.
Croatia is not to be considered a great team by that time but I think 1.5 years is not really that much of a long time to consider all these players gone. At the very least Modric could play here, and I know it would be near impossible for him to play in the world cup, so he will want to leave it after a certain tournament and I do not think that nations league would be that one.
Everyone knows that nations league is just a formal exhibition game for most clubs, they just train together and instead of having friendlies, they play in the nations league, this is why I think Modric will leave after euro cup, because he wants his last cup to mean something.
