Looking at the 3 rule guidance from UEFA, for me it simply is not good enough.

The way to combat this is simple. Don’t walk off in the first instance of any heard racial abuse but bring it to the attention of the officials. They in turn monitor this and if it is repeated then by all means remove the players from the pitch and abandon the match.

UEFA receive the Refs report and act accordingly by deducting the points from the offending fans team and award them to the offended team. If that didn’t stop the moronic ignorant knuckle staggers then nothing will.

If this did happen pity those idiots when their fans turn on them.
