Berlusconi addressed the squad at Milanello after yesterday's disappointing 1-1 draw with Catania and said: "You must lift your heads. You can still challenge for the championship.
"You must not give up. You proved what you're capable of last season in the Champions League."
Going into this week's Champions League clash with Celtic, stand-in goalkeeper Zeljko Kalac conceded: "We're a little down on confidence."
