Dangerous play is something like booting a ball while someone is trying to head it, an offence which is never penalised with a sending off as long as no contact occurs
What you mean is called "serious foul play". The direction from where the challenge comes from doesn't apply for this rule either btw, just whether the ref deems it to be lunging in, using excessive force or endangering an opponent's safety. Basically the rules give the ref a lot of leeway and while I think often enough refs don't protect players enough in England Moss was being a dumb piece of shit to send Xhaka off.
