Argentina v France (15:00 GMT)This week, the French squad was hit by illness, with Adrien Rabiot and Dayot Upamecano missing the semi-final win over Morocco and then Raphael Varane, Ibrahima Konate and Kingsley Coman all absent from training on Friday.
So that's the two first-choice centre-backs and the man who you'd think would step in all struggling.
It's not quite as dramatic as the situation involving Brazil's Ronaldo ahead of the 1998 final against France, but it does evoke memories of a nation being potentially compromised by a key fitness issue ahead of the big one.
