It is dodgy as hell. 9 reds from a team that commits the fewest fouls in the premiership. Bellerin, one of the softest players I’ve ever seen in an Arsenal shirt, has most yellows in the division.
I am pretty sure we also lead on things like yellows for time-wasting (i recall 3 including Pepe recently when we were tending to an injured player!) and foul throws (5 - all for Bellerin) which are largely inconsequential decisions but further indicators of bias.
You can argue that we shouldn’t put ourselves in a position where refs can influence the match but come on - it stinks to high heaven.
