Arsenal boss Arsene Wenger believes that the Premier League title could be heading to the Etihad Stadium by the New Year if Manchester City maintain their form.
Roberto Mancini's side are leading the way in the league, five points clear of title holders Manchester United.
The North West side are unbeaten in the league this season along with third-placed Newcastle United.
"If they are still there with that difference in December, then you can say it will be difficult to catch them," The Mirror quotes Wenger as saying.
"No team has no vulnerability in our league or any other league. They have quality. They can score goals, they can be efficient. They are the ones to catch.
"They had some impressive away results, especially at Tottenham and Man United but we have to see. The potential is there but we will see on a longer period."
The Gunners have worked their way up to seventh in the table, on equal points with Liverpool.
