The City manager says last season's title came too soon.
"Itâ€™s difficult to win a championship here," said Mancini. "We won last year but we won very quickly. Usually when you manage a team that hasnâ€™t won for 40 years, I think that you need four, five or six years to win a Premier League.
"We won the championship after two years and itâ€™s clear itâ€™s more difficult the year after but we had the chance."
