Pic: Anyone know who the Irish fan snapped at the Nigeria/Bosnia game is?

Eagle-eyed viewers may have seen the first Boy in Green at a World Cup game last night. We're wondering who the mystery fan was?

So far at this World Cup we've had a Galway man going mad on behalf of Croatia and only yesterday Cavan was getting some love from a fella on Copacabana beach but until last night, we hadn't seen any Irish fan at a game in our own beloved jersey. But that duck was broken during the late game yesterday when a crowd shot during the Nigeria/Bosnia match showed a man clad in our green jersey, and a bit of a vintage one at that.

We'd love to know who the fan is so if you have any details on the solo Boy in Green, do let us know on Twitter or mail us at editorial@JOE.ie. We might even have a prize for you...
