This is a tough one.. France hasn't lived up to its expectations so far. Belgium has on the other hand been able to adapt, as seen in their last game vs Brazil where Lukaku played on the right side of the pitch in order to exploit the spaces left by Marcelo.
France could exploit the weaknesses of Belgium back line of 3 with Mbappe but I think Belgium will be able to adapt. Only doubt that I have is who will replace Meunier, for me Chadli isn't convincing enough

I think Belgium will win 3-2
