The Brazilian started seven games for City last term and Calenda says that he would like to make an impression at the Etihad Stadium.
Speaking to Radio Sportiva, Calenda said: "He has had an unfortunate season, it can happen.
"Now he wants to prove his worth in a Manchester City jersey and achieve the World Cup's call with Brazil."
The 31-year-old, who has won 66 caps for his country but has not played for the national team since 2011, had been linked with Italian side Roma. However, Calenda says that a move to the Eternal City is unlikely to happen.
He added: "Interest from Roma? Italian football is going through a bad time economically so it is difficult to take players with this kind of salary."
City are expected to return to pre-season training next week.
