If you do that and there's even a chance another player is going to come in contact with it, you're risking being sent off.
I'm not arguing two different things. Mane should have never done what he did. This isn't a blind bicycle kick, this is him charging at a ball and lunging with his boot high. He CHOSE to do that. He was NOT under control. I don't know how you could ever think doing that is anything remotely close to that.
I'm sorry, but no. It's Mane's fault his eyes were up when Ederson came in. It isn't Ederson's fault. Challenge for the ball, sure. Put your boot at neck level? Not unless you're sure nobody's around. It's excessive, stupid, dangerous and has no place in the game.
Mane got a red and 3 games. Luiz got a yellow.
And yes, you are absolutely arguing two points. 1.) Whether it deserved a red. On that we don't disagree. 2.) That Mane had no excuse for doing what he did. We disagree.
If you think that Benteke had no excuse going for that ball then fine. The only difference is that Herrera backed out. Ederson charged in. Contrary to popular belief, soccer is a fairly violent and dangerous sport.
