Eight cities in six different countries could host the second leg of the Liverpool vs RB Leipzig Champions League tie on March 10.
Liverpool are leading the last-16 tie 2-0 after Tuesday night's first leg, which was played on neutral territory at the Puskas Arena in Budapest, Hungary.
The second leg was scheduled to be played at Anfield but Leipzig won't be able to travel to Merseyside as things stand because German government rules state they would have to quarantine for 10 days on their return.
Germany has imposed strict travel restrictions in an effort to prevent the new Covid-19 strain that originated in the United Kingdom spreading there.
