I really think people are confused about this sending off here, hes not been sent off for high feet. Hes been sent off because he was late in a dangerous tackle.
If a player clears the ball and another player misses it going for the ball and ends up going knee high on the other players its a straight red. Right? Everyone agreed?
Well this is the same but the players FACE!!
The keeper won the ball, Mane misstimed the challenge and kicked him in the head.
Imagine the keeper boots that clear and Mane lunges late and takes him out at the knee, no one would argue with the red. THATS HIS FACE.
Its not about the height of his feet, its a dangerous and misstimed tackle, he missed the ball and took out the man. Its not even for one nano second debatable.
Its a crying shame because clearly there was no intention, but it doesnt matter, it was an awful misstimed challenge and he had to go.
If he had knicked the ball it may have been a different story.
