It's fairly obvious both should be banned. I know it technically should be "off the ball" and Zlatan's wasn't, but it's so blatant that it'd set a worse precedent not to punish it.
The only thing I don't get is HOW the ref managed to miss both of them. In the replay he was very clearly looking straight at Zlatan as he elbowed Mings in the face. So is he now saying he didn't see it and would have sent him off if he had? Because if he didn't see it, what WAS he looking at?
He was refereeing the game by staring at where the ball was but not actually looking at what was happening?
I mean I really have no qualm with Zlatan being banned for elbowing someone in the face, but that makes the referee very clearly a liar...and if you're allowing people who you know are prepared to lie about what they see, act as referees, you really have no integrity to base anything on.
There's been so many incidents similar to this over the past few months, where a ref seems to have clearly seen something and just decided to ignore it or pretend it was something else.
