Owen Hargreaves joined Keys & Gray on Friday to preview this weekend's Manchester derby.
The former England international spent four injury-plagued years at Manchester United before a brief spell at their rivals City.
"Both teams have shown that they are great going forward but they will both probably acknowledge that they haven't been at their best," he said. "Defensively is going to be important and getting the balance of the midfield right.
"Both managers right now would take a draw. I don't think they would admit that but they would take a draw. It's not a title decider but it's an important game."
