Really don't see the point of that. You could make an argument both ways about the red card and penalty, so neither will be deemed a glaring mistake.
Worrall clearly fouls Fernandes and it's inconclusive whether Boly gets around on the cover, while Danilo catches Rashford for the spot kick. He didn't clean him out but it was a tired waft at the ball against a quality player who accelerates past opponents so quickly. We'd have been screaming for it at the other end - can't have it both ways.
As many have said already, the main thing to take from the game is the palpable sense of disappointment this season that we didn't secure a result, against the resignation of getting spanked (four times) by United last year. We've come a long way and it feels like significant progress. I'd suggest forgetting the officials today and moving on to the next match with good heart.
