Juventus GM Beppe Marotta has hailed the impact of Massimiliano Allegri this season.
Allegri succeeded Antonio Conte over the summer and has Juve now boasting a 100 per cent record.
"After what Conte did here the scepticism over Allegri was understandable," said Marotta.
"When replacing a Coach who has won three successive Scudetti and set so many records the backlash can be negative.
"This is because the Coach is the leader of the group, but I believe also that behind the Coach and the team there has to be a strong club with the right to support the role of the Coach.
"We have to give great credit to Allegri - he did well at Milan and was not an unknown when he arrived.
"He won the Scudetto in his first year, he is a winner and when we gave him the squad we did it responsibly, knowing that he had the right attributes to coach Juventus."
