A narrow victory over Canada left the Red Devils top of Group F while their opponents in this game secured a morale-boosting point against Croatia.
Given what happens today, Belgium can guarantee their progress with a game to spare - and even as group winners if they win and the other game ends in a draw.
Morocco have not reached the knockout round since 1986 and may need another result in Al Thumama to grow that confidence.
