Why Does Barcelona Have The England Flag On Their Crest?  why does Barcelona, a Catalan club, have the England flag on their crest? Yes, right there. You see it, right? Even English clubs don’t have it, so why Barcelona, a club that plays in the Spanish league?  Anyway, it’s still a relevant question: why does Barcelona have the Cross of St. George on its crest? St. George wasn’t even Spanish.
