"Argentina fans drag their team through matches - it was a like a home game for them against the Netherlands in the last eight, and it will be the same against Croatia.
"With Morocco, I also think how it would be a great story for an African team to make it. Too often at this tournament, we disregard teams from outside Europe and South America, but Morocco have made people think differently.
"They would be my romantic choice to make the final, but I am less sure about their chances against France."
