UEFA has a history for disciplining clubs after politically-motivated incidents.In July 2015, UEFA fined Barcelona £21,000 for displaying pro-Catalan independence flags at the Champions League final against Juventus in Berlin.In 2013, Celtic were also fined £42,000 for an ‘illicit banner’ that showed William Wallace and Bobby Sands alongside the message: ‘The terrorist or the dreamer? The savage or the brave? Depends whose vote you are trying to catch or whose face you’re trying to save.’  It was deemed an ‘incident of non-sporting nature’ and Celtic were put in the dock for it.
