Liverpool 's clash with Atletico Madrid in the Champions League last month should not have happened. That is the view of the city's metro mayor Steve Rotheram who questioned why the UK government allowed the match to take place as the coronavirus spread rapidly.
There have been accusations that allowing Madrid fans, while their city was under a partial lockdown, to travel to Anfield has contributed to cases of COVID-19 on Merseyside.
The government's deputy chief scientific adviser, Angela McLean, said the links warranted further investigation and it was an "interesting hypothesis".
Liverpool's defeat by the La Liga giants on March 11 was the last major football match to take place in the UK before all leagues suspended their seasons.
