My issue is the lack of consistency across all competitions enforcing it. Few ZL games I've seen they just let it slide and don't bother but then a few other games they're particularly anal about it.
For example on Sunday for Croatia v Croudace Bay. Crabs Ressie player correctly sent off for calling opposition player a Fat C**t but then Croatia coach giving both barrels to somebody in the second half and calling them a C**t which was heard by everybody goes unpunished
If it is going to be enforced it shouldn't just be as you feel like it. All in or not at all.
