Manchester United manager Ole Gunnar Solskjaer has admitted his side need to get back to being a "proper team" after being dismantled by Manchester City at Old Trafford.
An own goal from Eric Bailly and a strike from Bernardo Silva earned City a 2-0 victory with huge pressure now piling back on the Norwegian.
Two weeks after their harrowing 5-0 home defeat to Liverpool, this one was arguably as one-sided, with City rarely needing to get out of second gear.
It took the champions just eight minutes to open the scoring when Eric Bailly inadvertently turned a Joao Cancelo cross into his own net.

Ole Gunnar Solskjaer offered an honest take on the state of Man Utd
Chances came and went for the visitors, with Kevin De Bruyne and Gabriel Jesus both coming close to doubling their lead.
And with just seconds remaining of the opening 45 City did have their second with United's shambolic defending gifting Silva a golden chance.
Cancelo's cross was allowed to run by Harry Maguire before his England team-mate Luke Shaw did the same, leaving Silva free to poke past David de Gea.
Solskjaer attempted to change the flow of the game by bringing on Jadon Sancho at half-time, taking off Bailly and reverting to a back four.
But United struggled to get a glimpse of the ball as City cruised to a dominant derby day victory over their local rivals.
Defeat leaves the Red Devils eight points off the top and facing up to the prospect of being as low as 10th before the international break and Solskjaer conceded his side are well off the pace of the genuine title challengers.
He said: "At the moment we are, but we've got to get back to what we started to look like. And we started to look like a proper team.

"Get back to what we looked like at the end of last season and the start of this one.
"We've been through this a few times, of course since the last game we played here [Liverpool], it's been a very difficult period. We've gone away from what we used to be.
"We need to be on the front foot more. I can't look at myself and say this is how I want Manchester United to play.

"I'm sure when we come back, the players will be fresh and the demands on me and the players are going to be high. We've got to get back to what we looked like before."
The United boss had eased some of the pressure regarding his future beating Tottenham last time out, but the nature of the defeat to City is sure to pile it all back on.
But he remains defiant he is the man to turn it around, adding: "I have good communication with the club. I want the best for United and as long as I'm here I want to do everything I can to improve this."
