Nearly 17,000 football fans from Bayern Munich and Sevilla ignored warnings from health experts in their respective countries to attend the UEFA Super Cup final in Budapest, the annual match between the two winners of the main European trophies, the Champions League and the Europa League.
The Germans in particular headed for Hungary and the match on Thursday nights, with some local medical specialists warning that they could be heading into a biological bomb, with the game played in the middle of a coronavirus hotspot.
There were precautions in place all fans had to wear masks and had their temperature checked before they entered the stadium. And, once inside the ground, they were meant to observe social distancing, although there was little evidence of it, with fans pictured congregating together.
Fewer than 20,000 fans were allowed to attend the game in a stadium with a capacity of over 65,000.
Meanwhile, a group of Sevilla fans were filmed on a plane heading to the game partying, in images that appeared on social media.
In reality, some German fans did heed the warnings. There were more Sevilla fans in the stadium, with reports that the German club had returned a large number of their ticket allocation, apparently in response to the perils outlined by the German health authorities.
All those Bayern fans who still went ahead regardless, have been offered a free Covid-19 test until Saturday afternoon, in a specially designed area at their Allianz Arena in Munich.
Those who test negative will avoid having to self-isolate for 14 days.
The game, the first major football match to feature fans since the lockdown began, went ahead against the wishes of many. Even the Mayor of Budapest has said that, he would have played the match behind closed doors if he had the legal powers to enforce such a move.
Last week, Bayern had to abandon plans to allow a limited number of fans to attend the opening game of their new Bundesliga campaign against Schalke following the intervention of the regional government.
That followed a sharp increase in the number of new coronavirus cases in the Bavaria area.
