Funny video has emerged from Copenhagen of Irish fans cheering customers of a branch of women's lingerie store Victoria's Secret ahead of their team's first leg World Cup qualifier against Denmark.

According to the filmer, hundreds of Irish fans had gathered outside the Dubliner pub in the Danish capital, turning the area into an unofficial fan zone. Their attention then turned to customers of Victoria's Secret, in front of the pub.

In the video, one female customer can be seen coming out of the shop and swinging what appear to be a pair of knickers, to the delight of the fans.

"Everyone who was involved saw the funny side of it and really enjoyed a great day," the filmer wrote online.

Ireland host Denmark tomorrow at 7.45pm at Aviva Stadium, Dublin in the return leg.

++CLIENTS PLEASE NOTE: THIS VIDEO HAS BEEN LOOPED++

This was a video I took outside the Dubliner pub on Saturday in the lead up to the first leg of the World Cup play off between Denmark and Ireland.

All the Irish fans gathered in the thousands and made this our fan zone. As the day commenced the laughs and cheers where getting better and louder ... as people (men and women) entered and exited the Victoria's Secret shop we cheered them on ... everyone involved saw the funny side of and really enjoyed a great day.
