Manchester City star Yaya Toure believes Manchester United face a difficult task in retaining their Premier League crown.
The Citizens star believes the Old Trafford outfit are "struggling" under David Moyes and will find it hard to keep their league trophy this season.
United just overcame Stoke City this past weekend thanks to a 3-2 victory over Stoke City, meanwhile the Citizens lost to fellow title rivals Chelsea at Stamford Bridge thanks to a late Fernando Torres goal.
And, after the weekends fixtures, the Red Devils are just two points behind their local rivals, however City's powerful midfielder told Goal.com: “United will find it hard to defend the title since they have a new manager, David Moyes, and are really struggling."
And, after City have already been defeated three times this season and only sit a place above Moyes' side, Toure has admitted the club face a challenge in order to win the league themselves.
He continued by saying: “I must admit that we have a tough battle ahead to reclaim the Premier League crown.
“We must work extra hard as a team to compete with Arsenal, Liverpool, Chelsea and Manchester United."
United and City turn their attention to the Capital One Cup this week as Moyes' side host Norwich City tonight and Manuel Pellegrini's side travel to St James Park tomorrow evening.
