Are people being intentionally obtuse or is this what it means to be a biased, hypocritical football fan?
Casemiro's was a red. Doesn't matter how you want to slice it. If you challenge for the ball and there's a follow through (even if you make contact) it is a foul. In Case's case he make contact with the player's shin. That would get checked all day and deemed a foul. Not intentional, yes. Unfortunately, absolutely yes, but red card, yes as well.
I didn't see a replay of Bruno's but that might be debatable and should have been VAR'd at least for perspective.
Also doesn't look like most on here know the handball rule. It effectively states that players are allowed to support their body weight in the event of a fall, and hand hitting the ball as a result of that is not considered a handball. It is that simple. Again no grand conspiracy against us on that call.
