Tottenham beating Tromso in the Europa League might easily have turned into something of a non-event, especially for Arsenal fans, who are far too busy celebrating their run of form to worry about their neighbours.

However, while Jermain Defoe was banging in a brace of goals and Christian Eriksen was scoring a sweetly struck first for the club, a bit of action in the stands was getting fans talking.

A travelling fan from Norway was spotted putting on an Arsenal shirt during the match, and instantly became a hit on Twitter.

Come On Tromso, or whatever you are called! Your fan base has just expanded by 2.8million... — The Goon (@theOzeal) September 19, 2013

Whether "Tromso girl" entertains any of the marriage proposals put her way by Arsenal fans (we have a hunch she won't), she certainly provided a talking point.

Will any of the Arsenal fans reciprocate by wearing a Tromso shirt this weekend while the Gunners take on Stoke at the weekend? Or will Tottenham fans turn up in Norway for the return fixture and wear the kit of Tromso's fierce local rivals, Bodo/Glimt?

You never know—football fans have a knack of not letting this kind of thing go...
