Speaking ahead of Sunday's trip to Fiorentina, Donadoni said: "We'll have to be concentrated and aggressive.
"The team is in good shape. We are going to Florence to play our game. We still have margins for improvement, above all from a mental point of view.

"Eventual modifications in tactics and style can only be made when I have a complete squad.
"Fiorentina are always an intimidating opponent. Injuries aside, they have a squad that can allow for some absentees. Gilardino won't be there, but that is offset by Mutu's return.
"Fiorentina have started the season a little slowly, but they are improving their style of play and had a great game against Juventus."
