Former Manchester City coach Sylvinho backs the appointment of Pep Guardiola.
The Inter Milan assistant coach played for Guardiola at Barcelona.
Sylvinho told Omnisport: "Manchester City are working in the correct way, they have got some players, a new coach. They give managers time – Pellegrini got three years, Mancini started his work many years ago.
"It is very important to leave two or three seasons for each coach and now Guardiola has got time to work on the Champions League.
"I am absolutely sure Manchester City will play great football, but to win the Champions League in three years is not easy, it is difficult to say that. But they will try to play great football all over the world.
"Of course it is part of the plan for Man City to bring in Guardiola to build a new team to go to the final of the Champions League and to try to be champions, but it is not easy and he knows it."
