The British Government currently has no plans to ease coronavirus quarantine restrictions on overseas supporters for the knockout stages of Euro 2020.
Tournament director Martin Kallen told the PA news agency on Friday that talks between UEFA and the Government were ongoing to allow those key matches to be attended by foreign spectators without the need for a lengthy quarantine period.
But a Government spokesperson said: "Overseas ticket holders will be able to watch Euro 2020 matches at Wembley but will be subject to travel restrictions and requirements in England and at their place of origin, including testing and quarantining. There are no plans to change travel exemptions for ticket holders.
"We continue to work very closely with the FA and UEFA to support a fantastic Euros and to communicate the latest travel guidance to fans. We will keep this under review over the course of the tournament."
Wembley will host the semi-finals and the final along with two last-16 matches.
The UK has the toughest entry requirements of any of the host countries, requiring visitors from amber list countries to quarantine for 10 days on arrival.
Travel between the other host nations – particularly other European Union countries – is largely possible with proof of a recent negative PCR test.
Kallen told PA: "We are in a dialogue with the Government, we are looking at what's possible.
"The Prime Minister and the British Government said June 21 would be the date when in principle everything should go back to normal. And if it goes back to normal, what will the rules say for foreigners to come to the UK who are not on a business trip?
"We are in a dialogue and we hope that we can achieve something if the situation allows it, that something could happen on that side.
"Other countries are more flexible, they expect the negative PCR test which is for 72 hours or 48 hours (before arrival) and they come in and out, with the exception of countries that they have put on the red list in their country.
"We are looking at how the situation is moving and what could be achieved."
Government sources had previously said it was unlikely that the current restrictions will be eased at any stage of the tournament with the country at such a decisive stage of its unlocking programme. The Government has committed to giving a decision on June 14 on whether the final step of its easing of restrictions can take place the following week.
