[ad#m1] Poznan, a kind of celebration where the fans jump up and down, hand in hand and showing their backs. Pretty famous with Manchester City fans.
And we have now witnessed an entire stadium doing the Poznan. It looks quite incredible when the whole stadium does it.
It happened in the Australian A-League as Western Sydney Wanderers won 2-0 against Brisbane Roar. The crowd at the Parramatta stadium went ballistic as everybody joined in the Poznan. And someone with great sense of timing managed to get the video.
Watch the whole stadium shake below.
