Korea Republic are last in Group F with two defeats, but if they beat Germany and Sweden lose to Mexico, the Taeguk Warriors may advance to the Round of 16 with Mexico. Germany and Sweden both have one win and one defeat apiece, while Mexico lead the group with two wins.
Korea Republic, whose best performance in the World Cup came on home soil in 2002 where they finished fourth, know it will be a tough challenge but Shin said they would give it their all.
"We have to know why Germany are the No. 1 team in the FIFA rankings," Shin said. "They are the defending champions but we will do our best."
Korea Republic's campaign would have been over following their 2-1 defeat to Mexico had Germany not beaten Sweden by the same score in the later match.
Toni Kroos' second-half stoppage goal not only ensured Germany - who lost 1-0 to Mexico in their opener - stayed alive but Korea Republic too.
Shin said he believes the players will do their job against Germany, although he lamented that captain Ki Sung-yueng is out for the match. Ki suffered a left calf injury during the match against Mexico.
"As a captain, Ki did his job 100 percent and was a mentor for the players," he said. "I believe other players will fill the void left by Ki and Park Joo-ho (also injured) in the next match."
