Just checking what minimum capacities have been announced for the grounds used for the Euros:
Hampden - 25%
Bilbao - 13,000 - 25%
Bucharest - 13,000 - 23.34%
Dublin - no guarantee given - likely to be dropped from the host cities
Wembley - not announced yet - but FA want 50% (45,000) - subject to UK government decision
Copenhagen - 12,000 - 31.5%
Amsterdam - 12,000 - 21.6%
Baku - TBC
Budapest - TBC
Munich - TBC
Rome - 25%
St Petersburg - 50%
It seems that only Russia and the FA are having higher capacities - capacity for Hampden is similar to those other host cities that have announced.
In case anyone missed it - the deadline on fan capacities was also extended today to 28 April:

Last chance saloon for the Irish one would think - but also been done you would think to ensure the Germans are ready.
