The Old Lady won 2-0 over Bologna, with Dybala opening the scoring, before Ronaldo assisted Matuidi’s strike.
Allegri opted to play the pair without Mandzukic, but believes they can strive with the Croatian forward.
Comparing the performance to Juve’s previous Serie A game when they won 2-0 at Frosinone, Allegri told reporters: “Paulo [Dybala] had a good game like he did in Frosinone. It’s normal he needs to grow.
“They [Ronaldo and Dybala] played a good match tonight. The more they play together and the better they know each other, I think there is room for improvement.
“I think playing with the three in front and Mandzukic in the middle makes both play better.”
