Seeing as both City goals were conceded by faults from players that were unchanged (blind was responsible for the 1st, and played striker onside for the 2nd and Fellaini should have pressed higher up to cut the pass out to silva for the 2nd even before that)
City probably deserved one (the one that practically hit both posts before going out for a goal kick), but Zlatan should have scored at least one more before 1/2 time
The Utd performance in the 1st half was **** , unquestionably, and City 's build up play was a lot better than anything they did in the last 1/3 for the most part.
It could fairly be argued that Utd should have actually been ahead at 1/2 time even after playing **** for 30 odd minutes (and carrying Rooney)
Blind isn't a centre half and should never be played as one when Smalling and Bailly are available.
edit - seeing as Ottemendi watched the ball over his shoulder and moved his elbow to meet it (as can clearly be seen on MOTD) its daft to say it isn't a pen (although I can see why in r/t it wasn't given , it still should have been awarded)
