Mancini said: "I am confident about the season ahead now. This is my team. I am happy with what we have done in the summer. I think we have signed some good players and we are hoping to sign some more.
"The only problem I have is I will only be able to work with some of the players two days before the start of the season. Some of them will be late training because of the World Cup.
"If we work well, though, we will have a good chance. I think we have improved."
