There is a fear Bundesliga games could be held behind closed doors in Germany due to rising Covid-19 infection numbers.

While the so-called fourth wave is sweeping through the country, the federal states differing rules lead to patchwork-like measures.

Federal states with the highest numbers, such as the state of Saxony, abandoned amateur games.

Northern-Rhine-Westphalia allows only vaccinated or recovered fans to attend the games. In Bavaria, most amateur leagues have started their winter break; others continue.

Other sports such as handball, ice hockey, and basketball clubs have to follow different rules depending on their state rules.

Clubs of different sports have to adjust their hygiene concepts nearly every week due to state rules. An increasing number of sports follow the 2-G rule.

For 2021 World Championships in Handball, which run from December 2 to 19 in Spain, only 2-G athletes are allowed.

In many states, clubs remain uncertain due to constantly changing rules.

Upcoming games can’t be planed; as new rules might be implemented when infection numbers keep growing.

For Thursday federal state governments and the German federal government are expected to implement new rules to break the fourth wave.

Aside from amateur sports, professional football is facing difficulties. The Bavarian state premier Markus Soder demanded to make vaccination for professional footballers compulsory.

To demand vaccinations from employees to some extend is colliding with German working rules. So far, it isn’t allowed to investigate employees’ vaccination status.

While changes won’t affect the 12th round of matches of the Bundesliga, uncertainties remain for the following games. RB Leipzig stopped ticket sales for the game against Leverkusen on November 28th.

Many clubs fear new losses when having to face games behind closed doors again.

Positive cases among footballers continue to trigger difficulties. Not only 2020 treble winner Bayern is affected. Several players had to attend quarantine as contact persons after defender Niklas Sule was tested positive.

The incidence revealed that several players such as Joshua Kimmich aren’t vaccinated. Now the positive test of Josip Stanisic caused attention as the defender is vaccinated and recovered.

League CE Christian Seifert is demanding a convincing strategy from politics. “We have heard a wide range of proposals.”

This weekend Bundesliga games are rune under different rules. Full capacity of fans is allowed in Augsburg, Hoffenheim, Freiburg and Berlin. Dortmund, Leverkusen, Gladbach, Mainz and Bielefeld have reduced the number of fans.

The clubs follow a range of 3-G to 2-G. Some demand to wear masks in the entire arena, while others only demand to wear masks when fans are leaving seats.

VfB Stuttgart chairman Thomas Hitzlsperger seems on high alert as games behind closed doors or further restrictions endanger the club’s economic situation. To exclude vaccinated and recovered fans would counteract the current vaccination campaign in his perspective.

Bayern claimed to have lost up to four million euros due to games without fans; Stuttgart speaks about two.
