Shin admitted morale among his players had been "quite low" following the Sweden result but emphasised the "atmosphere has improved" and they were "fully prepared" to face Mexico.
MEXICO: Guillermo Ochoa, Edson Alvarez, Carlos Salcedo, Hector Moreno, Jesus Gallardo, Hector Herrera, Andres Guardado (Rafael Marquez 68'), Miguel Layun, Carlos Vela (Giovani dos Santos 77'), Hirving Lozano (Jesus Corona 71'), Javier Hernandez. Mexican fans may not fear this South Korea team, but they won't have peace of mind until Mexico's name is written in ink at the top of the group.
Hernandez's strike means Mexico will progress to the last 16 if Germany fails to beat Sweden, with Son Heung-min's added-time stunner not enough to stop South Korea from staring at a potential group-stage exit.
Ki suffered a left calf injury during the match against Mexico and will not be available for South Korea's duel against Germany.
"I think that your question invites me to say we are our own enemies, however I don't think so", Osorio said when asked who Mexico's biggest enemy was now that so many people have jumped aboard the bandwagon.
The hapless Koreans, who have no points after two games and have only won one of their last 11 World Cup fixtures, will be eliminated if Sweden draw or win against Germany.
South Korean goalkeeper Jo Hyeon-woo stays on the ground after giving up a penalty to Mexico's Carlos Vela in the teams' Group F match at the FIFA World Cup at Rostov Arena in Rostov-on-Don, Russia, on June 23, 2018. No joke: wards Colombian coach Juan Carlos Osorio at the start beat themselves the current world Champions of Germans (South Korea lost to the Swedes).
"We don't have a lot of resources but, nevertheless, just before the World Cup we had a lot of injured players and after the end of this game".
The record for penalties at the World Cup stands at 18 in 2002.
South Korea legend Park Ji-Sung also spoke to reporters in the media center in Rostov on Friday and stated that his team has to move on from that loss against Sweden.
"First we need to show our performance on the pitch and then need to wait because actually Mexico is a better team than us, but in football you don't know".
