Moreno is a scapegoat. His tackle on Shaw was unfortunate, he made the right challenge, Shaw's leg got stuck in the middle. And this one isn't even an intended challenge. The ball was at knee height, he tried to kick it and missed it, resulting in him hitting the player at the same height. Reading the comments on the 2nd challenge, people really are clueless about tackling. "He had no intention to play the ball" my ass. He's a physical player, yes, but not anything particularly evil.
If you want to see an actual butcher on the field who goes after people to intimidate them, they are dime a dozen. Pepe is one.
