Well, your point is that Arsenal would have had some suspensions from previous similar tackles. I take your point.
But, I make the point that, if there was some sort of effort made to root out such tackles and then try and keep some form of consistency with refereeing decisions, then maybe players would stop trying such ridiculous reckless challenges.
Of course, the slow midfielders and centre-halves will always have to attempt lunges/stretches for the ball, but the sort of carry on that Taylor did today HAS to go.
