The future of Allegri remains clouded, despite him insisting he expects to remain in charge.
Matuidi told La Stampa: “We had a good first half against Roma and needed to score.
“Allegri's done a great job here and I hope he stays: he's shown great quality and he's a great Coach.
“We have to think about playing and having a good game on Sunday night at the Stadium against Atalanta to celebrate the Scudetto.
“We'd like to give a good impression of ourselves because we have to finish well so we can celebrate the Scudetto in front of our fans.
“I'm happy at Juve, I feel at home and I have no problems. I'm staying 100 percent and Raiola will take care of my renewal: he knows more than anyone."
