The new five-year deal will keep Mancini as manager at the Etihad Stadium until the summer of 2017.

Mancini still had a year left to run on his previous contract with City, but the Italian has recently been strongly linked with the role of Russia boss.

He told the club's official website: "I am delighted to be able to give all of my efforts to Manchester City for a further five years. The opportunity which exists to build on our recent success is enormous.

"Manchester City is a fantastic football club, from the owner, chairman, board and the executive team, through to the players, staff and fans. I am very much looking forward to the challenges and excitement ahead."

Interim chief executive officer John MacBeath added: "Roberto's managerial credentials have been well proven in Europe for many years and in leading a team which has won the FA Cup and an unforgettable Barclays Premier League title in successive seasons, his ability to manage in the English domestic game is also undisputed.

"This new agreement allows Roberto to focus on the challenge of guiding a team which is capable not only of defending the Premier League title, but one which can compete for European honours."
