Interim Manchester United boss Ralf Rangnick has claimed that his side need to model themselves on rivals City.
The Red Devils travel to the Etihad to take on the Premier League leaders on Sunday, and Rangnick highlighted the need for United to learn from the way Manchester City and Liverpool have developed over the years.
City have won the league title five times in the past decade, while Liverpool have won it once, but have also lifted the Champions League. Meanwhile, United continue their wait for silverware.
"My focus was, and still is, on developing the current team and getting best out of this season," Rangnick said on Friday.
"But City and Liverpool have continuity and consistency as their head coach, for the past five or six years. They have very clear identity, how they want to play.
"I know Jurgen [Klopp] in person and I know Pep [Guardiola} from time in Germany. He also has a clear idea how he wants to play.
"This is the secret behind their success. They know exactly how they want to play, they have a corporate identity. Not just for new players.
"This is what all the top clubs have in common. This is something that needs to be developed at Manchester United."
In his own press conference, City boss Pep Guardiola dismissed the 19-point gap between the two Manchester clubs, refusing to see it as a weakness.
“I see the weakness points they have and I see the strengths points they have, but if I see this as an easy game I’m not going to sleep well,” he said.
Rangnick concluded, “To sleep well I have to see the best of them but when they don’t have the ball I try to find the weaknesses that they have. But of course always I think the best version of all of them. Otherwise I would make a mistake.”
