I was only using Bell and Murray as examples.
I have seen many similar tackles in the recent past get yellows or even go unpunished.
I don't know you call it mindless. I am sure Ralls knew exactly what he was doing and expected a yellow card.
I think is more 50/50 as to whether it was yellow.
Did you see Ings challenge on the Chelsea player yesterday.
Far more dangerous and a yellow card.
