In what will be their final match of the group stage, Belgium will face South Korea in Sao Paulo on Thursday.
During Belgium's first two matches, against Algeria and Russia, manager Marc Wilmots switched his first XI around. His substitutions were often impactful, rather than like-for-like.
Consequently, it's not completely clear yet how the Rode Duivels will line up this time around.
Will the midfield setup look the same as it did against Russia? Could Wilmots revert to the players he picked for the match against Algeria?
What about the attack?
Here, we take a look at a couple of selection decisions facing Belgium ahead of the match against South Korea.
