That's a two way street tbf. White players don't exactly get compared with black players. I dunno why it's seen as a problem that there are obvious differences and similarities that aren't just simply 'ah they're both black' - no one's comparing Drogba and Sammy Ameobi.
Why would they be though? White players aren't "powerful"
I also think people will go out of their way to find an accurate and favorable comparison for white players, however random (i.e. "Reminds me of Danny Murphy during his Liverpool days, this lad") vs. a handful of archetype black players ("hmm, well he's kinda like Drogba I guess. Or maybe Thierry Henry").
