Frankfurt said local health authorities have agreed to this figure which can include up to five per cent, or 1,750 fans, who have a negative PCR coronavirus test not older than 48 hours.

All other fans must be either vaccinated or recovered from a coronavirus infection to attend the October 21 game.

The number is 10,000 more than the 25,000 that were allowed to attend their group opener against Fenerbahce in September.
