The Red Devils were pipped to the top-flight crown by the Citizens in May, courtesy of Sergio Aguero’s late winner against Queens Park Rangers on the final day of the season.
United are currently three points clear of City as they look to prise the league title away from their fierce rivals, and with Chelsea 10 points behind the Red Devils, Ferguson expects a two-horse race with Roberto Mancini’s men,
“It will be difficult to think the two of us will collapse. I think it will be between the two of us.”
United failed to beat City in the Premier League last term, losing 6-1 at Old Trafford before being beaten 1-0 at the Etihad, but Ferguson does not expect Sunday’s outcome to have a huge influence on the destination of the title.
“It won’t mean a great deal because there’s such a long way to go until the end of the season,” he added.
“You can never be sure and you can lose to anyone. That’s the kind of league we’re in. It’s a tough league.
“The derbies had a big impact [last season], particuarly that 6-1 defeat, on goal difference. That’s what cost us.”
