And yet, you quite happily argued against my post by bring up the incident from 2 seasons prior, where Mane did compete for a mid-height ball and Ederson got injured as a result?
You can't have it both ways - either GK's head vs attackers foot is a competition that should be allowed or it's not. And if it's not, the referee needs to be correctly penalising whichever member of that incident has caused it to become dangerous. Sometimes that will be the goalkeeper.
i think the two situations are similar, but different. the ball height determines whether mane challenges safely or not
