It's a very interesting subject.
One thought is that a ball winning midfielder, say Henderson or Kante, the black player is more likely to be perceived as a "machine", a physical anomaly, whereas the white player is commended for their "graft", someone who achieves the same purely by desire rather than natural endurance.
I suspect its a lot more nuanced though. Presumably there is some physical differences (not a scientist, don't know) which would lead to black players being given roles (either by selectively or naturally assuming those roles) at a young age to take advantage of that, which in turn means they get less experience playing in one of the positions that get lauded for intelligence (deep lying playmaker, number 10). However every role or position, there are multiple ways of playing it, and all rely on some combination of intelligence and physicality. Is a white goal poacher more likely to be revered for their movement than a black goal poacher, who may be seen as a run in behind pace merchant? Maybe. Or maybe I'm wrong that there is any physical difference, and only think it's a possibility because of stereotyping. I'm not sure.
Additionally there are multitudes of exceptions to the rule. So many that it's possibly not even a rule, and a pattern is only visible if you look for it. This is 8am pre-work speculative off the cuff thinking, so don't get all angsty if anything in this post is incorrect, genuinely curious what other people think.
