I cannot comment on most of that, having not seen much of the second half.
So i will go with...
Yes, better than a lot we have had, but the bar is not set very high at all.
I cannot remember who it was now, but the little schit the grabbed and shoved over our player should have been booked straight away.
NO player stayed off for the 30 seconds required, in fact, if you see it again, i don't know whether the little schit was the 4th official or part of the Leeds set up, he was urging the referee to bring him on straight away, the referee should have followed the rule on his own 🤣
