I believe those Croatian players will surely be disappointed in themselves, there is nothing bad to lose to a good team like Argentina, but to lose 3-0 in a world cup semifinal is embarrassing, and i am sure they know they let down millions of their fans that were watching back home in Croatia. In 2018 they finished 2nd, they can still finish 3rd in 2022, their world cup isn't over yet, as they would play the loser between France and Morocco to decide who goes home in 3rd position, i know they would have loved to play in the final, but this is a good consolation, finishing 3rd out of 32 teams that started the tournament is a great achievement.
The defeat was very disappointing for millions of fans, but all the players tried their best from the first minute even though in the end they had to admit Argentina's advantage. Croatia will still be fighting for third place for the World Cup, and it is true that it will be a great achievement for them.
For today's game I hope Morocco can repeat their impressive performance against France. I know France are the better team in terms of quality but there is always a possibility to lose them if Morocco play well. It would be spectacular if in the end Morocco reached the final, it would be something very great for their football. But it's hard to expect them to win and I wouldn't be surprised if Morocco lost from France.
