As Morocco was the black horse of the World Cup, I believe most of Moroccan players will leave their current clubs. For example, Liverpool already uncovered their connections with Sofyan Amrabat who was one the best Moroccan players, and the French club Angers announced that they can't hold on Sofiane Boufal and Azzedine Ounahi due to the unrefusable deals they are getting for them. In addition, there are rumors linking Yassine Bounou with Barcelona. IMO, These players showed high quality and deserve to play for bigger names like Liverpool and Barcelona.
LOL.. one tournament changed the fate of several players in a matter of few weeks. I am not surprised for Yassine Bounou, as I thought that he was the best goalkeeper in the tournament (although FIFA gave the award to Emiliano Martínez). Achraf Hakimi was another Moroccan player who was impressive in the world cup. And these players are quite young (most of them are in the mid 20s) and therefore we can expect them to be a part of the top leagues for another decade or so. What happened to the Croatian players after 2018 edition will happen this time to the Moroccan players.
