I think the idea is by June about 60% will have been vaccinated in England compared to elsewhere in Europe. In addition it makes more sense to have everyone in one country under one authority ie policing, government policy etc as opposed to going around Europe and having to take into account each countries rules and regs on COVID. As some have said the draw is a bit flawed as some groups were done on the proviso that they had a host city.
If it is going to be played in England they’ll be a frantic plan for which stadiums will be used.
Wembley
London Stadium
Villa Park
Old Trafford
Etihad
Anfield
St James
Stadium of Light
Are the obvious choices then take your pick for the other 2-4 grounds from Elland Road, Hillsborough, Pride Park, KP, St Mary’s, Amex, Riverside.
Think Derby and Elland Road seem obvious to give as much coverage nationwide.
Can’t see them using more than 2 grounds in London but if they do Spurs stadium and Emirates could be used.
Good luck planning that one.
