I thought Lundstram’s was a red. That type of foul that stops a breakaway is of course usually a yellow, but when he is miles away from the ball, has absolutely no intention of playing for the ball, and it’s knee height, that’s a red for me.
I haven’t seen the Celtic game today but I’ve read online that none of the Celtic fouls merited a booking. I really don’t think refs are biased, just extremely incompetent. VAR will for sure help with that in this country.
