Spain - Saudi Arabia

In Belgium, there is no doubt that they are the favorites, even though they narrowly played against Egypt with a 1-1 score. But perhaps that cold shower was beneficial. It is very likely that they will win against Peru today. After all, they are a team of higher level of mastery in all competitions. Why do I choose under, it is mainly because of Iran's playing style. I have no doubt they will not engage in open play, as they would simply be outplayed. It is probable that they will start with a 5-4-1 formation. They will defend and try to slow down the pace and counterattack.
Belgium's offense is not as effective as it was a year ago. Plus, important attacker Doku will not be available. Against Egypt, Belgium struggled, just like in the qualifiers when they had trouble breaking down defensive teams like Iran.
However, their individual mastery is significantly better than Iran's and they should take the important 3 points, while Iran's best option would be a draw against Peru.
In summary, it seems very logical that Belgium will win against Peru and the game will end with less than 3.5 goals.

After drawing with Egypt, today Belgium needs to take 3 points and sort out things in the group. The team looked quite passive against Egypt and played more cautiously, but early missed goals by Egypt give them more opportunities to defend. On the other hand, Iran does not seem like a very defensive team. The level of skill definitely differs, but Iran should still put up a fight, so the Belgians should look to earn some corner kicks.
