Mancini: I Have No Doubt That Man City Will Win the Premier League © EuroFootball.com

Roberto Mancini has no doubts that Manchester City will defend the title of English champions.

Although the Manchester team won only two of the first five matches of the season, Mancini has not lost his optimism.

"We have to stay calm and work hard," the specialist said. "We will win the championship, but I agree that it will be more difficult to do it in the second year."

So far, the champions' defense is shaky - already letting in 14 goals in all tournaments, and we have failed to compensate for it in the attacking game.

"We have conceded only two more goals than last year," added Mancini. "Maybe we scored less, but striker Sergio Aguero had health problems."
