Manchester United manager Sir Alex Ferguson has side any team who wants to win the Premier League, needs to stay united through the course of the season.
While Sir Alex believes it's normal for frustrations to boil over around the relegation zone, he says tensions at the top end of the table don't bring success.
"You need unity. A team wins the League," The Express.co.uk quoted Ferguson, as saying.
Ferguson believes the experience in his team is vital at the nerve-shredding end of the season.
Mario Balotelli's feud with Aleksandar Kolarov in the 3-3 draw with Sunderland last Saturday weren't a great advert for City's temperament.
Ferguson said: "I wouldn't allow it. Obviously it can happen in a game." (ANI)
