Liverpool's last-16 Champions League match against RB Leipzig is reportedly under threat after the German government imposed a flight ban until February 17.
On Friday, chancellor Angela Merkel's government announced entry restrictions for travellers from the UK, Ireland, Brazil, Portugal and South Africa, to try to stop the spread of the more contagious coronavirus variants.
Liverpool are due to take on their Bundesliga opponents a day before the current ban is due to end in the first leg of their round of 16 encounter.
Now, according to the Liverpool Echo, that could mean the fixture is switched to a neutral venue if Jurgen Klopp's side are not allowed to travel to the Red Bull Arena.
