It was decent when Iceland did it but any attempt at imitation by fans in the UK is firstly going to look incredibly contrived and secondly almost certainly going to involve at most a couple of hundred people doing it which will sound as bad as it does when you hear it at the cricket. I'm not a fan of adopting chants just because they're popular in different countries or different teams.
"We Love You" has to be the most annoying song since every club in the country had a go at it.
