The stakes have never been higher – and the anthem will be sung like never before after Wales’ players called for the fans to lead the way against the Republic of Ireland.

Hen Wlad Fy Nhadau has a special place in the hearts of the Welsh side and its Red Wall of supporters.

It is a song that bonds them before games with each member of squad and staff linked arm in arm, with players having to learn the words to become part of the group.

Its power was seen when an a cappella version struck up in the Euro 2016 qualifier against Belgium in June 2015, inspiring Gareth Bale and co. to bat away the visitors and record a historic win.

And it has been heard during key points in games ever since, including in last month’s significant win over Austria where it culminated with Ben Woodburn’s winner.

But now Chris Coleman’s squad have come up with the plan to create an even more stirring rendition having been inspired by the defiant singing before the victory over Georgia in Tbilisi on Friday night.

The Georgian FA accidentally cut the music after the first verse and began to introduce the hosts’ own anthem – only for the 2,000 travelling fans to continue the chorus with guttural Gwlads.

And the players remained standing, arm in arm, to belt out the climax with them.

It’s seen the squad turn to the FAW and ask for the music to be cut after the first few bars and allow the choir of supporters to do the rest.

It promises to be a spectacular moment with the hope that it can inspire the side to victory which could lead to a second successive major finals.

Coleman knows how special the atmosphere can be and has called on fans to be excited about the prospect of the final game showdown.

And the manager has asked fans to be in their seats – especially in the song-leading Canton End – by the time his side walk out for their warm-ups.

Ireland are bringing 3,000 fans of their own, with many already on the streets of the capital.

But Wales hope the sight and sound of the Red Wall by 7pm will be the start of a very special evening at Cardiff City Stadium.
