It was really beyond everyone expectations, for Manchester United I'm not surprised they got such a bad result, even though basically they should have won the match because they were playing at home. But for Manchester City, it doesn't make sense at all, I agree with you who said that Wolves were just lucky to beat them, we can also see that one of Wolves goals was an own goal scored by Ruben Dias.
BTW, don't forget the result Luton Town got today, they finally got a good result in their sixth game in the PL. Now there are 3 teams left who don't have a win on their record for this season, they are Bournemouth, Burnley and Sheffield United.
Manchester United experienced another victory crisis, and Crystal Palace managed to avenge their previous defeat against United at Old Trafford. Ten Hag has not completely succeeded in concocting the right formula for the Red Devils squad, even though Crystal Palace victory would more accurately be called luck. Wolves deserve to be called the club that had great luck in the seventh week, because they were surprisingly able to beat defending champions Manchester City by a narrow score. City suffered their first defeat in the EPL, although they were disappointed because they were defeated by a non-seeded club, but it was not a big problem.
Yes Luton managed to change their bad luck for the first time, three points which kept them out of the relegation zone which is currently occupied by Bournemouth, Burnley and Sheffield. Liverpool has the opportunity to shift City position at the top, if they succeed in beating Tottenham.
