In your head.

Ireland put the doubters to rest with a monumental victory over reigning world champions South Africa at the Stade de France in Paris last night.

The victory ensured they remained undefeated at this year’s Rugby World Cup and sets them up nicely for their final pool match against Scotland in a fortnight with a likely quarter-final against the All Blacks in their sights.

The fans in the stadium played a huge role last night, with the Fields of Athenry giving Ireland a huge lift on the hour mark to get them over the line, but it didn’t stop there.

Once the final whistle was blown, Zombie, by the Cranberries, rang out at the Stade de France with the 30,000+ Irish fans erupting for the chorus in a truly special moment.

Ireland winger James Lowe was asked about the atmosphere in the stadium after the game and he couldn’t praise the fans highly enough.

“It was crazy,” Lowe said.

“When you walk around after the game, and from row one to row 80 – it’s packed.

“I know that there were a lot of South Africa fans there but when any Irish anthem came on that place lit up.

“You heard Zombie at the end there… it was amazing and hopefully we can carry that on throughout the tournament.

Up next for Ireland is a down week before taking on Scotland in their final pool match on October 7.

Until then, they can continue to enjoy every last bit of last night’s famous win.
