Gareth Bale has branded Wales' Euro 2016 quarterfinal clash with Belgium as the country's biggest game in more than 50 years.
Chris Coleman's side, participating in their first major tournament since 1958, take on highly fancied Belgium for a place in the last four on Friday.
And Bale, who has scored three goals in their four games so far in France, said the match was Wales' most important since losing to Brazil at the 1958 World Cup.
"We know about the quarterfinal in the World Cup in '58, so since then it's obviously the biggest game in Welsh football for sure," he said.
"It's one we're looking forward to and eager to get started. We just want to enjoy the occasion, take it all in and hopefully get into the semis.''
The fitness of captain Ashley Williams had been a doubt following a shoulder problem suffered in the round-of-16 victory over Northern Ireland, but the defender took part in training to ease further concerns.
"Ashley took part in most of training today, so I think he's OK,'' Bale said.
Real Madrid forward Bale has been at the forefront on and off the pitch for Coleman's side in France and is delighted to see Wales progress to the last eight.
"It's our time to shine," he said. "We're the only home nation left in the competition which is an amazing achievement in itself.
"The game against Northern Ireland was a very ugly game that was not suited to us, but to play badly and win shows the team spirit and character we have at the moment.
"We're very happy and very proud and will be flying the Wales flag high.''
