South Korea have not been able to use Hwang Hee-chan in the tournament thus far due to a hamstring problem, and the forward remains a major doubt for Friday's contest.
Son Heung-min will again be a certain starter for Bento's team in this match, with the 30-year-old set to win his 107th cap for the national side, while Napoli's Kim Min-jae will line up in the middle of the defence.
Cho Gue-sung scored twice against Ghana last time out and will again lead the line for South Korea, while Kwon Chang-hoon should retain his spot in a wide position.
There should also be a spot in the middle of the park for Hwang In-beom.
As for Portugal, Nuno Mendes had to be substituted in the latter stages of the first half against Uruguay last time out, and the defender has been ruled out of the rest of the tournament.
Danilo is also out with fractured ribs, while Otavio is a doubt with the injury that forced him to sit out the game against Uruguay last time out.
Raphael Guerreiro should come back in for Mendes at left-back, but Cristiano Ronaldo has been rated as 50/50 for the match after he missed Wednesday's training session.
Santos has confirmed that he will make changes for this match, with Diogo Dalot, Joao Palhinha and Goncalo Ramos all potentially coming into the starting side.

Ghana vs. Uruguay (Friday, 3.00pm)

Ghana have not reported any injury concerns from their clash with South Korea, so it would certainly not be a surprise to see the same starting XI take to the field for this match.
Mohammed Kudus was in brilliant form last time out, scoring twice, and his performances at the tournament have led to suggestions of interest from the likes of Barcelona and Liverpool.
Inaki Williams is again expected to lead the line for Ghana, with Jordan Ayew and Andre Ayew also set to retain their attacking roles in the three behind the centre-forward.
Meanwhile, Thomas Partey should be joined by Salis Abdul Samed in the middle of midfield.
As for Uruguay, Luis Suarez and Edinson Cavani have both struggled to impress at this summer's tournament, so it would not be a shock to see them start on the bench here.
Darwin Nunez could potentially be joined in attack by Maxi Gomez, who was bright off the bench against Portugal, with Suarez and Cavani potentially playing roles later in the contest.
Head coach Alonso is likely to resist the temptation to shuffle his pack, with the likes of Federico Valverde, Rodrigo Bentancur and Jose Gimenez again certain starters.
Ronald Araujo's fitness has been the topic of debate since the start of the tournament, and the Barcelona defender is again likely to be left out of the squad for this match.

Cameroon vs. Brazil (Friday, 7.00pm)

Andre Onana will not feature in goal for Cameroon, having been sent home for disciplinary reasons after a disagreement with the manager regarding style of play.
As a result, the more inexperienced Devis Epassy should get the nod between the sticks, as he did in the last match, while Vincent Aboubakar may be brought in to the frontline, having scored from the bench last time out.
Brazil have a number of players unavailable due to injury, with Alex Sandro the latest player to be ruled out after undergoing a scan regarding the hip issue that forced him off against Switzerland.
In his absence, Alex Telles is likely to come into the team at left-back, having been brought on for the final five minutes last time out.
Key player Neymar is also set to miss out due to an ankle injury which ruled him out of the last game, while another problem in the same area means that Danilo will not be in contention for a place in the backline.
Tite may also choose to rest a few Brazil players as a result of already qualifying for the knockout stages, so Bruno Guimaraes, Gabriel Jesus and Antony could be given some more minutes.

Serbia vs. Switzerland (Friday, 7.00pm)

Aleksandar Mitrovic scored his first goal of the tournament against Cameroon, and the talisman is now back to full fitness, ready to lead the line in the Serbia attack.
The supporting cast are likely to come in the form of Sergej Milinkovic-Savic, who is enjoying an impressive season with Lazio, while captain Dusan Tadic should feature on the right flank.
The Eagles will likely line up with a back three consisting of Strahinja Pavlovic, Milos Veljkovic and Nikola Milenkovic, who have been the choices in the previous two matches.
As for Switzerland, Noah Okafor is the only injury concern for Murat Yakin, as he currently has a muscle issue, although he was not a guaranteed starter anyway, having featured for fewer than 20 minutes against Cameroon.
Considering a point should be enough to secure progression for Nati, the manager may implement the same, more cautious approach he opted for against Brazil, with Granit Xhaka and Remo Freuler sitting in front of the back four.
Breel Embolo should be the choice in attack, as the only player to score for Switzerland up to this point, being supported by Djibril Sow through the middle, while Ruben Vargas and a returning Xherdan Shaqiri could support in advanced wide roles.
