Portugal 2-1 South Korea: What's your prediction?
South Korea let their emotions pour out when they lost a five-goal thriller to Ghana this week, but they can expect no sympathy on Friday from Portugal, who are determined to clinch top spot in their World Cup group.
South Korea must beat the 2016 European champions - as they did at the 2002 World Cup on home soil - and hope that the result of the other final Group H match between Ghana and Uruguay goes their way too.
South Korea have only one point after drawing their opening game against Uruguay and must beat Portugal to have any chance of progressing.
Portugal have already qualified but still need a point to guarantee top spot, a position that would likely see them avoid Brazil in the last 16, so they might not field a reserve team at the Education City stadium.
Portugal captain Cristiano Ronaldo's availability is still in question after he missed Wednesday's training and stayed at the gym to do recovery and specific exercises.
Portugal are not assured of finishing top of their group, a position that would likely see them avoid Brazil in the last 16.
"First place isn't guaranteed," coach Fernando Santos said on Monday. "We will go for top spot, and not just because of Brazil."
Santos is likely to be forced into more changes to his starting 11 after left-back Nuno Mendes suffered an injury in the first half against Uruguay and was replaced by Raphael Guerreiro.
