The move was a shock to many in Italian football as Pirlo had no experience managing at senior level. But there was no doubt about Pirlo's footballing knowledge, acquired during a decorated career in Serie A.
However, things have not got off to the best start under il Maestro.
After nine games of the domestic season, the Bianconeri are in fourth with four wins and five draws, the latest of which against minnows Benevento last Saturday.
There is still plenty of time left in the season, but with a club who has won the last 9 straight Scudetti, pressure is already building on the inexperienced Pirlo.
Many doubt that he can win the Scudetto, others even say he will not end the season at the helm of Juventus.
Asked about his thoughts on Pirlo, transfer expert Gianluca Di Marzio told Tribalfootball.com: "He is not [in a] precarious [situation] in my opinion, Juventus made a clear choice, that of focusing on a young coach, so it is a choice that must be protected, defended.
"I am convinced that they will go on. I don't know how much, but I don't think a couple of negative results will exempt it.
"For me he will end the season. He himself, when he accepted to make the leap, will have had his guarantees of being able to grow together."
Di Marzio details his long life in Italian football in his fantastic new book, Grand Hotel Calciomercato.
Having known Pirlo for some years, the Italian believes the former star player won't give up easily in the dugout.
"He has always been brave, he has received proposals to train before Juventus, but he had decided to start only for teams that were the Champions.
"He didn't want to start from B or C, like Gattuso. It is his style, a thin line between presumption and recklessness, he was like that on the pitch too, he thought he had something more than the others and he was aware of being a champion, but he is also humble, because he signed with Reggina on Saturday morning and wanted immediately go and play, when others would have said 'I'll wait for Monday'."
