In a report, it said a revenue shortfall was particularly apparent from ticket sales, which amounted to €22.4 million in 2020-21, compared to €520 million in the 2018-19 season prior to the pandemic.

In December 2020, the DFL had predicted a drop in turnover of about €1 billion during the 2020-21 season if fans had to stay away throughout the campaign.

“Over the past two years, the pandemic has already had a dramatic economic impact on the Bundesliga … Sadly, it is also affecting the current season, primarily because once again the stands often had to remain empty,” said Donata Hopfen, speaker of the DFL executive committee.

The report suggested that clubs had become less willing to make large investments in new players after transfer revenue also saw a further substantial downturn to €469 million, lower than the €533 million of the 2015-16 season.

“We are facing an unprecedented situation. The era of growth as something to be taken for granted seems to be over,” Hopfen added.

“Without a doubt, this will massively impact our development in the years to come.

“Nevertheless, considerable challenges always come with considerable opportunities. We must explore new avenues to make the German professional football future-proof while upholding our traditions and values.”

She did not elaborate, however.
