Yes, I thought my post made that clear. Noble gets away with committing ten fouls every game, then Aurier gets booked for committing three fouls. Herrera gets sent off for fouling Hazard after Jones has been let off with five fouls before that. For some reason, Diego Costa seems to be the exception to that.
I'm not suggesting that all referees are racists, I'm just saying that there's an element of tending to treat foreign players harsher. Whether that is because they can communicate with the English players and warn them verbally, foreign players treating the referee with more contempt or what it is, I don't know, but IMO there is something in it.
