Former Manchester United boss Ole Gunnar Solskjaer has already told Ralf Rangnick how to stop Man City.
United and City will face off against one another on Sunday in the Premier League in Rangnick's first taste of the Manchester derby. Earlier this season City took home the bragging rights with a 2-0 victory at Old Trafford.
Solskjaer's men were firmly second best at the Theatre of Dreams that day. An Eric Bailly own goal and a Bernardo Silva dainty finish enough to secure the points.
