Dublin will almost certainly be stripped of its Euro 2020 hosting rights tomorrow after Tanaiste Leo Varadkar admitted it was "too soon" to consider crowds at sports events.
Uefa set an initial deadline of April 7 for the original 12 host cities to provide minimum guarantees of capacity, as they plan for at least a limited number of supporters being in attendance at the games amid the coronavirus pandemic.
Nine of the cities have confirmed their plans, but Dublin, along with Bilbao and Munich, have not.
And Varadkar said yesterday: "The last I heard was that the organisers (Uefa) were looking at us to commit to have at least 25 per cent of the stadium full.
"We're cautious about that. We just think June is too soon. I think if they continue to insist on that, it will be hard for that to go ahead, which is unfortunate."
Uefa's executive committee had initially been set to take a final decision on Euros hosting on Monday, but the decision of 12 of the continent's top clubs to announce they had signed up to a breakaway Super League forced a delay until tomorrow.
The committee said on Monday it had tasked the Uefa administration with "drawing up concrete proposals" ahead of a final decision.
Group matches at Wembley, along with the last-16 match there, are set to be at 25 per cent capacity - 22,500 - while the hope is to be able to at least double that limit for the semi-finals and final at the same venue.
The Football Association said England stands ready to host additional games if asked, and it is understood Uefa would not limit themselves to playing matches only at existing venues and there have also been reports that Russia may take on extra matches.
The European Championship is set to start in Rome on Friday, June 11.
The Italian capital was only confirmed as a host city last week when local authorities confirmed that spectators would be allowed in up to 25 per cent of the capacity of the 68,000-seat Stadio Olimpico.
It joins eight other cities - London, Copenhagen, Glasgow, Saint-Petersburg, Baku, Budapest, Amsterdam and Bucharest - in being confirmed at this stage.
