Manchester United legend Bryan Robson feels Manchester City's defence is vulnerable going into today's derby.
Robson believes City will concede at the Etihad.
"I think the defenders are going to have to do really well against Aguero, if he is fit - that would be a plus if he is out," Robbo told MUTV. "Dzeko is a real handful and Silva, I have been told he is probably not going to play - that is also a plus. So if we can defend really well, it has been shown that City concede goals.
"From being a really top team and being champions, they can concede goals and we have got the strikers who can do that. So I think, instead of saying it is a midfield battle, I think it is how these defenders can cope with the forwards."
Pressed to make a prediction for the derby, Robbo continued: "It is going to be a close game, I don't think it is going to be a run-away for City like it has been for the last couple of games.
"As long as the lads stand up and have a bit of fight and spirit, because they are going to have to stand up to City, then I think we can take a point from the game."
