Arsenal were dumped out of the Champions League at the hands of Barcelona last night, going down 3-1 at the Nou Camp and 5-1 on aggregate.
The defeat means the Gunners have exited Europe's top-tier competition at the last-16 stage for the last six seasons, and leaves boss Arsene Wenger facing yet more questions about his future.
However that was only part of the story from a bad night in Spain for the north London club. A small group of the club's fans were recorded at a metro station by Onda Cero journalist, Carmen Juan, letting off a fire extinguisher and generally misbehaving.
Further footage emerged of the fans in the train station, which shows one fan shattering glass while others watch on. Some Spanish news outlets also claim Arsenal fans were spotted mocking beggars on the streets of Barcelona.

Arsenal's season now hinges on whether they can haul themselves back into the Premier League title race.
They were knocked out of the FA Cup by Watford before their Champions League exit, and face an uphill battle to overturn Leicester's 11 point lead at the top of the table with just nine games to go. They're also positioned six points behind rivals Tottenham, who have played a game more.
Wenger was adamant he is still the best man to lead Arsenal into next season and beyond, and insisted that Barcelona were simply the better team over the two games.
"We created plenty of dangerous situations where we couldn't take the chances we created, but I must say Barcelona's accuracy in the final third and the quality of the creativity, especially Messi, is absolutely exceptional," he said.
"You go through 90 minutes and you come out of a game, he didn't miss one first touch. At some stage in our sport you have to admire art and they have two or three players who transform normal life into art. I respect that. Of course, for me it's suffering but for a guy who just loves football, it's exceptional."
Next up for the Gunners is a trip to Goodison Park to take on Everton this weekend, before key league fixtures against Watford, West Ham and Crystal Palace.
