Achraf Hakimi and Yassine Bounou from Morocco, Julián Álvarez from Argentina, Aurélien Tchouaméni from France, João Félix and Rafael Leão from Portugal were some of the other players who caught my attention. And I agree with your observation that Alexis Mac Allister, Enner Valencia and Dominik Livaković performed exceptionally. My only regret is that now we need to wait for another 4 years to see these players in action, at the same time. Hopefully teams such as Italy and Chile will also be able to qualify for the next world cup.
The entire Moroccan team has outstanding players that any club should focus on but I am thrilled by the remarkable performance of Sofyan Amrabat. This outstanding defensive midfielder would be great asset to any team and they would not regret signing him. He was instrumental to Morocco's quarter finals victory against Portugal. He was full of strength and confidence and controlled the midfield ensuring that the Portuguese team don't have a free day. His market price before the world cup was Ten Million Pounds but I am sure that Fiorentina would not let him go that cheap. He has a contract with the club till 2024 but it might be possible that Fiorentina would be willing to sell him for a profitable fee. His agent has even confirmed that he has been receiving call from top clubs in Europe concerning Sofyan.
