Milan have already qualified for the knockout phase.
"It's a Champions League game and we want to do well," Allegri stated. "In the last eight games in which we had already qualified, we've lost five and all of those were at home.
"Tomorrow I want to see a side with the right concentration to avoid another loss. It is an important game for the club's finances and Italian football's ranking.
"We have to get a result also because we want to give some continuity after our win at Catania."
