The UEFA Super Cup between Bayern Munich and Sevilla could turn into football's 'superspreader event', fears Bavarian prime minister Markus Soder.
Thursday's clash between Champions League and Europa League winners is going ahead at Puskas Arena in Budapest with around 20,100 fans watching the game live despite the fact that it is in the centre of a coronavirus hotspot.
It will be the most attended event in world sport since Covid-19 put a halt to almost all public events in Europe back in March.
Soder warned: 'There is a high incidence of infections and we have to be very, very careful that we do not risk a football Ischgl.'
Ischgl is a ski resort village in Austria where at least 6,000 people are believed to have contracted coronavirus.
It has been dubbed 'Ibiza on ice' and has been used as a byword for anywhere that Covid-19 infections spiral out of control.
Soder's fears about Puskas Arena being another such place are underpinned by the fact that regulations in Hungary preventing the spread are far more relaxed than Germany.
A total of 3,000 fans from each club are allowed to attend in addition to the 14,000 Hungarians.
In Budapest the seven-day number of new infections per 100,000 inhabitants, has been stable for at 110. compared to 56.1 in Munich.
Any rate at 35 of higher means that games in Germany cannot be played in front of fans but that not true of Hungary.
There has been no spectator limit for domestic matches, oppositions fans are permitted to attend, and a mask is only recommended by most clubs.
Those who travel, including fans who spend less than two days abroad, do not have to quarantine when they come home, as per the current rules.
But Soder is attempting to overturn that ruling in cabinet on Tuesday, which would no doubt discourage some fans from making the trip to Hungary.
The coronavirus situation in Germany also appears to be worsening. Six out of the nine host teams had fans on the first matchday with spectators ranging from 4,600 to 9,300.
But Schalke's clash with Werder Bremen is now likely to be behind closed doors with the seven-day rate in Gelsenkirchen measured at 44.1.
Since the outbreak, coronavirus has caused 9,481 death in Germany (276,000 cases) and 694 recorded deaths in Hungary (19,499 cases).
