Victory on Sunday against Sampdoria confirmed Juve as champions.
“They deserved to win the championship," former Juve coach Ancelotti told Radio Anch'io Sport. “Compared to the past, Juve struggled a bit more.
“It was not plain sailing, there were more uncertainties, especially in the last phase. Sarri did an excellent job, he had the ability to adapt well and next year I'm sure he will have a bigger impact."
“Sarri deserves to be in a big club like the one of Juventus. The criticism is normal, but we are talking about the best team in Italy at the moment."
