Watch the disappointing moment a group of rowdy Arsenal fans let off a fire extinguisher on a Barcelona Metro platform, reportedly causing damage.

The Gunners once again crashed out of the Champions League at the hands of the La Liga giants, leaving their season in tatters.

Having also this week exited the FA Cup to Watford and fallen 8 points behind Leicester in the Premier League, the last thing they needed was their supporters tarnishing their name abroad.

With a clip surfacing of Arsenal fans letting off a fire extinguisher on the Barcelona Metro, that’s precisely what’s happened.
