Allegri is under huge pressure to keep his Milan job after a disastrous start to the season.
"I think Allegri is a great Coach," he told Sky Sport Italia. "I talk often with him, and it is clear he is very well prepared.
"At this time, it is very important that Milan go on to the field without any awe, and that the players play to their maximum.
"The Stadio Olimpico is a traditionally a good place for Milan, and I think the game against Lazio will be a good one."
