Contrary to expectations, 61st ranked Japan edged past 16th ranked Colombia 2-1, courtesy Yuya Osako's second-half header, in their opening match of Group H at the ongoing 21st edition of the FIFA World Cup here at the Mordovia Arena in Saransk.
Japan headed into the clash as clear underdogs, having clinched just one win in their previous six matches across all competitions.
Though Colombia too qualified for their straight second World Cup berth despite going win-less in their final four qualifying matches, they had a good record over Japan going into the opener.
In the previous three meetings between the two sides, Japan has failed to defeat Colombia as the former lost twice while they settled with draws in the remaining game.
However, Japan eventually managed to take revenge against Colombia and erase the bad memories of the 2014 edition in Brazil by clinching a triumph in the ongoing World Cup.
Just four minutes into the game, Colombia were reduced to 10 men as midfielder Carlos Sanchez was handed a red card -the first of the ongoing World Cup-for handling the ball inside the box.
