For victory over Parma, Ronaldo missed one good opportunity at the Stadio Tardini.
Allegri argued: “There are different difficulties a striker has to deal with in Serie A, but he had a good game overall. I am happy with what he's doing and the break for international duty will help all of us to be sharper.
“Mandzukic has always been generous, but even I didn't expect him to be in such good shape after the World Cup. Paulo Dybala is slowly finding his form too and did well when he came on.
Goalscorer Blaise Matuidi stated: “He is a great player and will score eventually, as he's very important for this team. He was unlucky this evening, but we will help him and he's got plenty of time. He was a little annoyed at not being able to score, but it'll come."
