Germany stunned by Japan comeback in latest World Cup shock

Another upset in Qatar after Argentina's win

Germany went ahead in the first half through an Ilkay Gundogan penalty.

Takuma Asano came on as a substitute in the last 15 minutes to win

How volatile this Germany team has become, especially when they appear to be in control

Earlier, Japan was on the verge of reaching the quarter-finals of the World Cup after defeating Belgium

A lot has to do with their 2-1 victory and their ability to make game-changing substitutions

Japan moved from first-half counter-attacking to a more pressing game and hit-in-transition style

Germany finished the game with Mario Götze, Youssoufa Moukoko and Niklas Fulkrug.
