So there is nothing to argue/debate for any penalty decision and red card as Ref and VAR both make the decision, so you can't argue against that.
"Its not a red card, Ref and VAR agree with me"
"It's a penalty, Ref and VAR agree with me"
I'm gonna defend him a little. He's just saying if the ref and VAR agree with him then it's not as if it's an unreasonable position to take.
As for the incident I can see it going both ways. Nketiah's is much more clear cut as he's facing the player he's lunging into and he's going in with studs showing, but I think the Vardy one - if not intentional - is not really dangerous play. Falling over and accidentally hitting someone is different from lunging in dangerously and accidentally hitting someone. Of course I would totally believe that it was intentional, even if not at the face in that case it's definitely a red.
