The former Juventus coach said: "Leonardo is seeking balance, like all coaches. He has offensive players of great talent. The philosophy of the Milan game is to create many goals, even if it concedes many, but as has happened in the last league match against Cagliari, this is linked to the absence of (Alessandro) Nesta.
"With the talent that Milan has in attack, it can make a difference at any time. It's when they're without the ball they are in distress.
"The four who play in the attacking department are the strongest in Europe."
