South Korea's players could be on a revenge mission against Cristiano Ronaldo and Portugal in their World Cup group stage clash.
The pair face off at Qatar's Education City Stadium in the final round of matches in Group H, with Portugal having already qualified for the knockout stages.
Fernando Santos and his team will ensure that they finish top of the group if they win or draw against South Korea, who need to win to have any chance of reaching the last-16.
But ahead of the game, it was put to Portugal boss Santos that Ronaldo could be targeted by the South Korea squad due to an incident while he played for Juventus.
The Italian side toured Asia in pre-season ahead of the 2019-20 campaign, when they played Tottenham in Singapore and Inter Milan in China.
Ronaldo played and scored in both of those games, but he then didn't play in a match against a K League Select XI in Seoul.
Ronaldo's no-show didn't go down well with fans in South Korea, with many of the 63,000 in attendance at the Seoul World Cup Stadium hoping to get a glimpse of the Portuguese superstar.
The fact that Ronaldo didn't play is still a sore subject among many in the country, although when a South Korean journalist put the incident to Santos in his pre-match press conference ahead of the clash - claiming that the Korean people were still "disappointed and angered" by it, and that the squad had been asked to get revenge - the Portugal boss gave a predictably short shrift.
"Well you have to ask Juventus and Ronaldo about that," he said.
"He went there with Juventus and that affects our match tomorrow how?
"I have huge respect for Korea and the Korean people and I’m sure Ronaldo does too."
Ironically Ronaldo could also miss this game having been rated as "50/50" by Santos, who is managing the 37-year-old's workload in Qatar and could choose to rest him for the last-16.
Santos was also asked about how Portugal will cope once free agent Ronaldo - who has been linked with a money-spinning transfer to Saudi Arabia - quits international football, and insisted that there are enough quality players in his attack able to cover for him.
"Well you can see in the past two games he was substituted, so we have a plan of course," he said.
On South Korea, he added: "Against Uruguay they had four or five good attempts, and unless we defend well we’ll be in a tough position because Korea are really strong."
