The Rossoneri boss says he will be without a number of first-team players for Sunday's Serie A meeting while suggesting Giampaolo Pazzini could be in contention to start
Coming into the game, Kevin-Prince Boateng is suspended whilst Riccardo Montolivo, Kevin Constant, Alexandre Pato, Djamel Mesbah and Daniele Bonera are all injured.
And Allegri admits he is going to have to reshuffle his pack for the meeting with the Granata.
"It is a shame as Montolivo had been improving and so had Boateng and Constant. I will have to use another three players on Sunday," Allegri announced at a press conference.
"Pato is still in pain and his knee is still bruised, so we will assess his condition next week."
The Italian coach then commented on who would play in goal, and suggested that he may give Giampaolo Pazzini a starting role up front.
Allegri added: "Marco Amelia could start in goal for us again tomorrow because he is in good form.
"It could also be Giampaolo Pazzini’s time to shine. I am happy with his performances because he has worked hard for the team, but he does need to score more goals."
