Motta was essentially heralded as the anti-Allegri. He was young, modern and, most importantly of all, progressive rather than pragmatic. Unlike Allegri, he had no major honours on his resume but he had just pulled off a minor miracle by leading Bologna into the Champions League on a tiny budget - and while playing some of the best possession football in all of Italy.
There was an acknowledgement that it would take some time to implement his strategy at Juve but managers don't traditionally get a lot of time to make things work in Turin, where the mantra is 'Winning isn't important; it's the only thing that counts.'
Motta, then, has two major problems right now.
Firstly, he's not winning games, he's drawing them, and, with just 27 points from 15 games, this is Juve's second-worst start to a Serie A season for 14 years.
Even more worryingly, the Bianconeri have bored everyone to tears on several occasions this season, and often in big games, against the likes of Roma, Napoli and Milan, while they were also involved in a dull scoreless draw with Aston Villa in their last Champions League outing.
Juve more than played their part in a fantastic 4-4 draw with Inter at the end of the October, which was viewed by some as encouraging evidence of things to come, and they also showed tremendous heart in coming from behind with 10 men to win away to RB Leipzig.
Certain players are also excelling, including Andrea Cambiaso, Kenan Yildiz, Timothy Weah and Nicolas Savona, but more media attention is being paid to Dusan Vlahovic, who is the team's top scorer, with nine goals, and yet is looking increasingly unsuited to the new manager's tactical approach. For better or for worse, Vlahovic is not Joshua Zirkzee, who has never been prolific (as Manchester United fans are discovering) but is capable of tying an entire attack together, as he did so impressively at Bologna last season.
Motta has also been criticised for refusing to play Yildiz out wide rather than in his preferred position through the middle and there have been accusations that the coach's obsession with vindicating his footballing philosophy is actually hurting the team and negatively affecting results as a consequence.
Certainly, much is being made of the fact that Motta's Juve have nine fewer points than Allegri's Juve at the same stage of last season - but are not generating any more excitement.
