Dybala scored his first goal in a month during Juve's 2-0 win against Genoa midweek.
Allegri said, “Dybala? I still have to decide who will play, but he's back among the goals and I'm happy about that.
“In 2017, he was the player who played more than anyone else, 38 times. If he's on the bench twice, it doesn't mean anything.
“Di Francesco? He's balancing a very difficult environment, where you can crash and burn in an instant.
“In fact, they're a team that have conceded just 10 goals and only one away from home. They're the team that have played the least number of minutes in Italy and have so much quality and balance.
“Mandzukic and Dybala? They can play together with three midfielders. It depends on our opponents and who plays at right-back."
