Why Was There A Poznan Happening At 5-0 Down Last Night?

If you can stomach watching Toni Kroos’ second again from last night, go to the 27 second mark and look at the background. There is a sizeable number doing the Poznan. Now our penchant for the craic is fairly well established at this stage but a Poznan at 5 – about to be 6-0 down? This thing may have jumped the shark a long time ago but if there was any doubt this is surely the moment.
