Manchester United boss David Moyes needs to steer his team to victory at the Etihad on Sunday, according to Sky Sports pundit Jamie Redknapp.
The Red Devils have failed to beat rivals Chelsea and Liverpool so far this season, and Redknapp believe Moyes can lay down a marker if his side can win at Eastlands.
Writing on his column on Sky Sports, Redknapp said: "Moyes - like Manuel Pellegrini - can really lay down a marker at his new club by winning the Manchester derby; that will really foster the fans' belief.
"Both managers want to prove that they were the best choice for the job and the best way to do that is by winning the match that means most to the supporters."
Redknapp believes that United's defeat at Liverpool has left Moyes under pressure and he could do without losing to the Red Devils' City rivals.
"If Moyes achieves the feat it will give him so much confidence, but he's under a lot of pressure after losing at Anfield and the last thing he needs is to lose at the Etihad."
The ex-Liverpool man also believes that a United win at the Etihad will go some way to winning over the fans that are still missing the Sir Alex Ferguson era.
Redknapp finished by saying: "The longer he goes without winning a big game, the more the pressure will build. But if United beat City on Sunday he will win over the fans who are still mourning Sir Alex Ferguson's retirement."
Moyes' side head into the game with just seven points in their opening four games, but a victory against their rivals will certainly prove a great result.
Pellegrini will have other ideas as he will hope to gain all three points in his first Manchester derby.
