In 2016, an estimated 100,000 Welsh fans were in France to witness Wales' march to the final stages of the tournament.

"UEFA still say they are quite hopeful that fans will be allowed back into stadia and it will still be held in 12 host cities," said Paul Corkery, from the Football Supporters Association Cymru.

Uncertainty is the theme - and Mr Corkery wants the governments to deliver a "clear pathway" back for fans to

It followed a pilot game, when 15,000 fans watched Bayern Munich beat Sevilla in Budapest to lift the 2020 UEFA Super Cup.

But Mr Corkery said that is not the position here, with a bid to host a trial at Cardiff City's stadium for 2,000 fans rejected by the

"With no plans in place for fans to return to matches here, I think the Euros could end up being held behind closed doors which will be devastating for fans," added Mr Corkery, who is from Merthyr Tydfil -

Anne and Mike Davies, from Tumble, in Carmarthenshire want to be among the travelling fans in 2021.

"Back in July we had no doubts about the Lions tour but now, four months down the road, we think perhaps it is looking a bit dubious," said the Scarlets season ticket holders.

He said the pandemic has already seen him cancel two European rugby trips for Scarlets fans, and the Wales tour of New Zealand.

"There was a lot of interest in fans booking for South Africa early on but there was a big

"We do understand this is a very difficult time for the sector and we will continue to work in partnership towards a safe reopening, when the time is right," said an official.
