IRELAND'S passionate supporters have got behind their team for tonight's must-win World Cup qualifier against Wales.
Irish fans took over the Welsh capital and turned the city into a sea of green ahead of the crucial clash.
A 'sensational' rendition of Amhrán na bhFiann saw the festivities continue inside the stadium – although a few of the Irish players appeared to have a problem finding their voice.
The rousing anthem from the fans saw some describe the atmosphere at the Cardiff City Stadium as being like a home game for Ireland.
Wales meanwhile stopped the backing track to their national anthem early so the fans and players could sing a capella, hoping to recreate the atmosphere generated when the Georgian football association accidentally stopped the music to Hen Wlad Fy Nhadau early ahead Friday's victory in Tbilisi.
Mathematically, Ireland can still finish as group winners but should Georgia fail to shock current leaders Serbia, Martin O'Neill's men must beat Wales to finish second to have a chance of making the play-offs.
Sensational rendition of Amhrán na bhFiann. This is it. We are underway in Cardiff. Come On You Boys In Green! #COYBIG pic.twitter.com/1BaYTTsvdN

Irish anthem starts. Lauren says "is this the Irish theme tune?" ?

Am I being unreasonable in thinking that the Irish team should know the words to their own national anthem? #COYBIG

Every player and the coaching staff sang the Welsh National anthem loud and proud. About 3 Irish players sang ours.. embarrassing
