Mario Mandzukic scored the only goal of a tense game.
“It's an important victory because we kept a clean sheet, we suffered and in the first half were a bit stubborn, not running any risks," Allegri told Mediaset Premium.
“The result was crucial and the lads deserve compliments for that. Gonzalo Higuain did well on the Mandzukic goal and his goals will come, he just has to continue playing. There's no point feeling sorry for yourself, these are moments every striker goes through."
He added: “It's not a stronger or weaker Juventus than last season, it's simply different. Comparisons are for others to make, we just have to work to ensure we reach March in good shape and in the running for all our objectives."
