The entire weekend will be a buildup to Belgium-Portugal.
Either the No. 1 team in the FIFA World Rankings or the Euro 2016 winner will be out of the tournament on Sunday.
Golden Boot leader Cristiano Ronaldo spearheads the Portugal attack and leads the tournament with five goals, but three of those have come from the penalty spot.
While Ronaldo will be in the spotlight, the defense will be vital in determining if Portugal advances far in the competition.
It let up six total goals to France and Germany, which is a bit concerning with an in-form Romelu Lukaku in front of them Sunday.
Additionally, the Portuguese have to find a way to silence Kevin De Bruyne, who made an immediate impact on the Belgian side when he appeared as a halftime substitute in the second group game against Denmark.
Portugal have some chance creators behind Ronaldo in Bernardo Silva, Bruno Fernandes and Diogo Jota, but none of them have been as effective as De Bruyne at Euro 2020.
De Bruyne and Lukaku have the potential to match whatever Portugal throws at the Belgian defense, and the Manchester City man could be the ultimate X-factor in the contest.
Prediction: Belgium
