The Samurai Blue came back from a goal down to pick up all three points against the European giants in their Qatar 2022 opening game.

Another day, another huge upset at the 2022 FIFA World Cup!

Germany, one of the favorites for the title, kicked off their campaign on Wednesday, taking on Japan in their first game in Group E, and due to their talented players and brilliant manager, many expected the European giants to march to a comfortable victory.

And after their first-half performance, this prediction seemed inevitable. Hansi Flick's men dominated the Samurai Blue and were unlucky to come away with a mere one-goal lead, as Ilkay Gundogan 33rd-minute penalty was all that separated the two sides.

In the second half, however, things took a turn for the worse for the four-time FIFA World Cup champions. Muller and Co. missed a couple of opportunities to double the lead and were eventually made to pay as the Asian giants grew into the game with time.

Japan made a number of changes in the second half and those proved crucial as two subs Ritsu Doan and Takuma Asano both got on the scoresheet to pull off a remarkable comeback victory. And that's not all! Mitoma and Minamino, who did not get a goal or an assist on paper, were the two subs who combined brilliantly out wide for the equalizer.

And Arsenal defender Takehiro Tomiyasu was also brought on the tighten things up at the back, even making a crucial block in the dying minutes despite appearing to be battling through injury.

This result sent social media into overdrive as fans flocked to Twitter in large numbers after this breathtaking showdown. This unexpected result bares a lot of resemblance with Saudi Arabia's historic 2-1 win over Argentina on Tuesday and it's not simply due to the score line.

Two heavyweights were undone despite scoring a first-half penalty, with lackluster second-half performances leading to their demise. While this shocking defeat leaves Germany with some huge questions, one thing is certain: the fans enjoyed this match! Check out the best tweets below.
