Incredible performance from Manchester United and this shows everyone in the whole league that Manchester City has a really bad defence and when their offence is having an off day like last night, surely any team can beat them.
3 angle: upholstery players first time I heard this term hehe
I believe that City didn't try enough in this game as they have the safety of 3-1 from the first match.
It was normal that United is going to try their best in order to score at least 2 goals and qualify to the next round. I wouldn't judge the performance of both teams from this game, but from the first one.
