There is no excuse, but the matter was dealt with, both by the club and between the players. This strikes me as some sort of performative exercise. If the FA really want to be serious when it comes to racism, then a few weeks with lip-readers and subsequent fines/warnings/education programs would be far more effective. I think if you ask many black and Asian players, they will tell you that whilst welcome advances have indeed been made, there is still an awful lot happening every single day on training grounds and at matches which goes unpunished. I can guarantee that banning Bentancur for 6 to 12 matches will not achieve anything beyond resentment and a wave of counter-commentaries, especially nearly two months after the action which took place off-season.
(Just to clarify, I'm not condoning what was said whatsoever, but there is clear dialectic here...it was wrong and it does not need further investigation given the context of the situation)...
