A lot of them have Afrtican heritage even if they hate to admit it or not. Not all of them but a lot do. They are all a bit ashamed of it, really. It's hard not to when 1/3 of Iberia was apart of the Moorish Caliphate for 600 years. Same goes for Southern Italy and bit and parts of South-Eastern Europe with the Ottomons. Look at Pedro and Xavi they look a lot less typical European and more Moorish than the likes of Mata and Iniesta. But in the end it's alright, innit? Doesn't really matter, still the same person.
