Arsenal fan group promise mystery display before Barcelona match

Fair play to Arsenal fans, they've been doing what they can to improve the oft-criticised atmosphere at the Emirates Stadium.

As with other top clubs, the Gunners' fan groups have been working hard to make things tick in North London, and one group - REDaction Gooners - have big things planned for the visit of Barcelona. Tackling issues with "supporter participation" head-on, the group has promised a pro-Arsenal mosaic ahead of the Champions League last 16 tie, calling for fans to be in their seats 10 minutes before kickoff to get the most out of the display. https://twitter.com/REDactionAFC/status/701410275656908800 https://twitter.com/REDactionAFC/status/701411073585455105 https://twitter.com/REDactionAFC/status/701411672070742017 The eagle-eyed among you will know it's not the first time we've seen an impressive mosaic ahead of a huge European night for the North London club. Before the 2013/14 meeting with Bayern Munich, fans combined to produce this stunning work which helped generate a stirring atmosphere around the whole stadium. https://twitter.com/bolterous/status/436443615032655872
