Bayern Munich are preparing to play their upcoming home matches behind closed doors at the Allianz Arena as Germany reacts to a spike in coronavirus infections.
Europe is currently being hit by a surge in cases, thanks in part to the new Omicron variant, with Bavaria in particular taking a number of measures in a bid to halt the spread.
All Christmas markets in the area - usually a huge hit among residents and tourists - have been cancelled, and football is now also heading back behind closed doors.
The national government are consulting on Tuesday to decide next steps, but Bavarian Prime Minister Markus Soder has already made his own decision, insisting: 'It makes no sense in the foreseeable future to admit viewers again.
'It is an important demand that we decide today that we will no longer admit viewers in the future. If that doesn't work at the federal level, we would do it for Bavaria alone.'
Soder then justified the move with a message from his Twitter account: 'The high mobility when traveling to and from the club is currently irresponsible. Football is a great role model. We now have to reduce contacts everywhere.'
Angela Merkel, the German Chancellor, and her successor Olaf Scholz, are set to discuss the Covid crisis with the heads of federal states at midday on Tuesday, where a final decision for the whole of the country will be made.
Champions Bayern, Augsburg and Greuther Furth are the three Bundesliga teams currently affected in Bavaria, with three more second division teams also in the region.
Two cases of the new Omicron coronavirus variant were detected in the southern German state of Bavaria at the weekend.
The two people with the variant entered Germany at Munich airport on November 24, before South Africa was designated a virus-variant area, and were now isolating, said Bavaria's health ministry.
The two had come forward for further investigations after they heard about the new variant, which has caused global concern and prompted a wave of travel curbs.
The Bavarian ministry said anyone who had been in South Africa in the last 14 days should immediately reduce contacts, take a PCR test and contact their local health authority.
'Bavaria has responded early and quickly to the very new variant,' a ministry spokesperson said. 'Everything must be done to stop it spreading.'
Of passengers arriving from Cape Town on Friday, 50 are in quarantine in Bavaria. Two foreign passengers tested positive for coronavirus and being investigated for the Omicron variant, the Bavarian ministry said.
In Germany, only 68.3 per cent of the population of about 83 million is fully vaccinated, far behind the rates in southern European countries such as Portugal and Spain. Some 10 per cent of the population has received a booster shot, said Spahn.
Germany recorded 67,125 new coronavirus cases on Saturday, the Robert Koch Institute for infectious diseases said. More than 100,000 people have died with COVID-19 since the start of the pandemic.
