Allegri was happy with victory after Sunday's defeat at Inter Milan.
“I was satisfied to get back on top of the table and we did well," Allegri told Sky Sport Italia .
“The lads took the right approach, though perhaps when 2-0 up we should've controlled the tempo, and instead we poured forward looking for a third goal with a little too much haste.
“Still, it's a good answer to the rather excessive criticism of our performance on Sunday against Inter."
Paulo Dybala has still not scored a single goal this season.
“He did well on a technical level. He didn't score, but was good at extricating himself from the Cagliari traffic and using his technique for that. I am very happy with what he's doing."
