When South Korea lost to Ghana in a five-goal thriller this week, they let their feelings out. However, Portugal, who is determined to win their World Cup group, will show no mercy to them on Friday.
South Korea must defeat the 2016 European champions, as they did in their home country at the 2002 World Cup, and hope that Ghana and Uruguay's final Group H match also goes their way.
After Monday's 3-2 defeat to Ghana, striker Son Heung-min broke down in tears, and coach Paulo Bento received a red card for arguing with the referee as his team was about to take a corner kick.
Bento won't be on the bench when Portugal plays.
According to assistant coach Sergio Costa, South Korea will overcome their disappointment.
Costa stated, "We clearly deserved a win."For the next game, you can rely on us."
After drawing their first match against Uruguay, South Korea only has one point and must defeat Portugal to advance.
Twenty years ago, in their final group match, South Korea defeated a 10-man Portugal team that included Bento.Portugal did not advance to the next round as a result of the result, but the Koreans went on a run that got them to the semi-finals.
Portugal defeated Ghana 3-2 in their first match in Qatar, followed by a more controlled 2-0 victory over Uruguay on Monday.
