Milan have surged to the top of Serie A without the former World Player of the Year in the starting line up and appear to be more balanced.
Speaking to Mediaset, Allegri said: “Right now he is out of the team but there isn't anything bad about it.
“I choose the team on the basis of the upcoming games and the condition of the players. Rino Gattuso was out at the beginning but won his place back.
“Massimo Ambrosini was also out and Robinho too. I told him that Milan is a big opportunity and he is now taking it in the best way possible.
“There will also be need of Ronaldinho. Like everyone he must put himself in discussion.
