The Argentine manager believes that having a year's experience of working in and winning the Premier League will stand his side in good stead to retain their crown
After arriving from Malaga, Pellegrini went on to secure two trophies in his maiden campaign in England - the Capital One Cup and Premier League.
With neighbours Manchester United getting to grips with new boss Louis van Gaal and a fresh system, the Argentine is optimistic of sustaining success at the Etihad Stadium into a second season.
"Maybe last year, when I arrived here, nobody believed that we could win the title because it was my first season here in England but we did it," he told the press.
"This year we have the advantage that I already know the players and they know me, we have already won the title. It is difficult for a team who wins the title to repeat it but we will try to do it.
"I think the most important difference was work. We were just starting the season in a new style of playing.
"This year we know how to do it, we have new players that must understand also the way we want to play but I think it is important to continue playing that way."
