"I'm sure the injuries and poor physical condition is hurting us," said Manchester City target Bresciano. "Against Torino, we dropped off considerably as the game went on.
"We still have to work hard in training to fix this. We must stay patient, however, because this Palermo is stronger than last season."
Asked about City's interest, the Australia international added: "My focus is on only Palermo. If a new offer arrives in January, then it will be up to the club to decide."
