Roberto Mancini: Yaya Toure deal 'very important' for Manchester City

Manchester City boss Roberto Mancini says Yaya Toure's new contract is "very important" for the future success of the club.

The midfielder signed a new four-year contract on Thursday which will keep him at the Etihad Stadium until 2017.

Speaking ahead of City's derby game against Manchester United on Monday, Mancini also feels his club "don't deserve to be 15 points behind" in the Premier League - but admits the title race "is finished".
