Look I am the first to say that I think rarely does a player EVER go into a challenge like that with the intent of ending a players career.
I am willing to give him the benefit of the doubt that it was just mistimed and slightly incompetent, however, that doesnt change the fact that it could have, and if you look closely nearly did, break Matic's leg, you see it bend ffs!!
He should be punished so players think about it before going in with a rush of blood to the head.
I'll also be the first to say Matic should not have reacted like that, because if you do, you leave yourself open to a red card. (though I personally think it should have been yellow). But on closer inspection of the tackle, you can see why he was pissed.
