I think they possibility wanted to but the govnt were unwilling to provide quarantine exemptions for UEFAs 3000 affiliates (guests, sponsors, delegates etc).
This is the real issue..............correct move by the Govnt IMO but was always likely to mean UEFA finding somewhere else to accommodate the 'important' people. Utterly daft to have 7,000+ people travelling internationally to a neutral country to watch two teams play who could meet at a neutral ground within 2 hours of their own. Could have had a bigger number of fans attending here too.
