Good question, as that could be confusing and seen as counter to tradition. Braithwaite actually does have his Caribbean father’s surname. As for the other two players whose Danish mothers laid down with African men, the fathers were simply out of the picture by the time they were raised, so they were given the names of the head of household. England is still ostensibly ~85% white as a population, give it take a few million new Pakis every couple of years. How they have created a ~40% negro player pool is astounding, embarrassing, and requires a textbook-length explanation.
