It’s really stupid. A red card is a sending off and a game ban.
I absolutely do think UEFA should have the right to add additional games to the ban, but surely this should only be for the really egregious situations? AWB went for the ball, not malicious. He missed it, it was a bit high, and so he got a red. Deserved probably. But its what happens in football. I don’t get why they would ban for something like this. I think these bans should be for something malicious or unquestionably reckless. So taking AWBs tackle for example, if, say, he made no attempt for the ball, or was so significantly far away that he never really had a chance at it, or he used excessive force over and above what he had to / unusually so.
