This was my account of the refereeing on a refereeing website - got a mixed response!
Mr Moss didn't put a foot wrong - for 115 seconds, then things went downhill. On 116 seconds it seems to me that he failed to award a penalty to City and a Red card to Saiss for wrestling Sterling to the ground as he was about to shoot.
A delightful pass from Cancello allows Sterling to play the ball just inside the penalty area and get ahead of Saiss, Sterling tries to stay on his feet under the challenge from behind by Saiss and just as he is about to shoot is pushed to the ground. To me rather more of a penalty than the clip I have seen for United against Norwich. Perhaps it was because the red card would have to have followed that the penalty wasn't awarded so early in the game. It would however have had a much greater impact on the game than the later red card and the dubious penalty given later.
On 6 m 23 s Grealish got away from Dendoncker and was brought down from behind - free kick awarded - could easily have been a yellow card but seemed to me that these two decisions set a rather high threshold for red and yellow cards - compared with later decisions.
In the 11th minute Traore charges into Cancello, nothing given a minute later Cancello returns the complement on Traore, again nothing given.
Also in the 12th minute Sterling is again wrestled to the ground right in front of the AR.
Result throw in to Wolves.
Then in the 18th minute a reasonable penalty shout as Jesus gets between the defender and the ball and is kicked on the leg for his troubles. I have mixed feelings about this one: Jesus has put himself in a position to attract the foul. However these are regularly given - the award to Salah seems the same sort of situation, Mr Oliver gave two penalties to Leicester last season where Vardy did the same, Calcello received a red card when Wellbeck did much the same against Brighton last season and so on. Shortly after Cancello fouls Traore and should probably be a yellow card - nothing given.
Diaz then makes a similar challenge on Traore as the one on Sterling earlier, wrestling him to the ground and receives a yellow card - in isolation this is an OK decision but in the context of previous decisions it is pretty inconsistant. The inconsistency continues when Rodri makes a similar challenge to the earlier one on Grealish and receives a yellow card. So when Jiménez tries to pull back Rodri by the arm and then tries to trip him a yellow card follows and as he tries to block the free kick the inevitable second yellow is given. It certainly seemed to me that the criteria for yellow cards had changed from his earlier decisions.
And so it went on, and we have a handball against Jesus where so far as I can tell the ball is nowhere near his arm but hits the chest and shoulder.
Finally in the 7th minute of added time to the first half City have another, to me credible, penalty claim. When a Grealish cross, which had a good chance of reaching Sterling or Bernado on the edge of the six yard box. is blocked by the arm of Kilman and deflected back to the keeper. Kilman's arm is reasonably at his side but he does move himself (including his arm) about a yard into the path of the ball and it hits him between the elbow and the bottom of his sleeve, he appears to pull his arm behind his back after the ball has hit it. So in my view this should have been a penalty although I don't think the one in the second half actually hit the arm but deflected downwards from the chest and armpit.
The second half continued in the same vein of inconsistency but I think there is enough here to say both on the balance of play and on the balance of refereeing decisions City were not particularly fortunate to achieve a win.
