The match had to be moved to another country because of travel restrictions for those returning to the United Kingdom from Denmark.
“The reason for the change in venue is the UK Coronavirus regulations, which dictate that people returning from Denmark must spend 14 days in quarantine,” Dortmund said in a statement.
“Instead, Midtjylland and Liverpool — led by former BVB coach Jurgen Klopp — will now go head-to-head in Dortmund.”
The city of Dortmund on Thursday confirmed to ESPN that it has been “selected as the host city” for the Dec. 9 Champions League match which would go ahead without fans as they have been banned from stadiums across Germany since early November.
Liverpool, FC Midtjylland and UEFA are all yet to confirm the change of venue.
The UK government announced in early November that all who “are returning to the UK directly or indirectly from Denmark will need to self-isolate along with all other members of their household until two weeks have passed.”
Klopp had seven highly successful years at Dortmund where he won two Bundesliga titles, one German Cup and reached the 2013 Champions League final.
After taking over Liverpool in October 2015, he returned for a Europa League match in 2016 and in 2019 was a star guest when Dortmund CEO Hans-Joachim Watzke unveiled his biography at the stadium.
