Valter Birsa is again tipped to start given that Kaka is still not totally fit after recent injury.
Allegri said: “Kaka has arrived with great enthusiasm, it’s just a shame he got injured. He’s an important signing for us as he raises our quality.
“He can’t play 90 minutes right now, but he knows how he can help his teammates.
“I’m not surprised by Birsa,” he insisted. “He has great quality. He’ll certainly do well tomorrow if he plays. He’s in good form and I’m happy as he deserves it.”
