Tudor was the first non-Italian coach to have held the position in 19 years, and he lasted just 24 games before being given his marching orders.
Loss of identity
Just 10 victories in his tenure gave him a win percentage of 41.67%, one of the lowest in recent memory, hinting at precisely what Spalletti needs to do in the job to help turn this Italian institution around.
With 10 matches played in the current campaign, Juve are actually in a reasonably healthy position when all is said and done.
Their 18-point haul places them sixth, but only three points behind Inter in second and four behind leaders Napoli.
Arguably, it's the loss of identity that's one of the most problematic areas which needs addressing.
After having landed Napoli's first Scudetto in three decades, Spalletti knows the blueprint for success, though he'll need all of his man-management powers to get the best out of players who have failed to perform over the past couple of seasons.
Time for Koopmeiners and Vlahovic et al to step up
Big stars such as Teun Koopmeiners and Dusan Vlahovic need to come to the fore, though, in fairness to the latter, his game time under Tudor was somewhat sporadic.
As with all players, the confidence bestowed upon them from the bench can often work wonders.
What has been a huge surprise for many, however, is Spalletti's immediate decision to drop Koopmeiners back into a left centre-back role.
A player who has been known more for playing a midfield role with aplomb, the Dutchman has looked comfortable in both games so far under Spalletti's direction, and building attacks from the back already appears to be part of the new modus operandi.
Koopmeiners looks set to be central to the success of such a system, too.
Yildiz suffering from burden of responsibility
The brilliant Kenan Yildiz also needs to be found a permanent home in Spalletti's new set-up, and whether that remains out wide and drifting in off the wing, or as a creative No.10 more centrally, remains to be seen.
At 20 years of age, it often appeared that the youngster had to carry this Juve side, and that responsibility has clearly weighed heavily on his shoulders from time to time.
To get the very best out of Yildiz, he has to be allowed to play with a certain degree of freedom, whilst accepting that there must always be purpose in his performance.
Alongside Yildiz, Vlahovic will be expected to pay his rent in goals. Goals that have been lacking of late.
After finding the net in the opening two games of the season against Parma and Genoa, the Serbian has managed just one more domestically, against Udinese in the final match before Spalletti was appointed.
Only one goal from Jonathan David
Jonathan David was signed over the summer, and he too has a point to prove, given that he's only scored once, alongside Vlahovic, in the season opener against Parma.
A stated aim of finishing in the Champions League positions has already been espoused by Spalletti, and it's believed that he will earn a permanent deal automatically - his current one runs until the end of 2025/26 - if he does just that.
Vlahovic and David's goals will almost certainly be key to that ambition.
Francisco Conceicao, Khephren Thuram and Andrea Cambiaso are three more players of the highest quality who have also underperformed.
So, aside from shoring up a leaky defence that has already conceded 10 goals - the second most of the top eight Serie A clubs - the real job that Spalletti has on his hands is to bring back the dynamic, front-foot possession-based football for which Juve were long masters of and known for.
Trust the process
With Spalletti being the third permanent manager - fifth if you add in caretakers - since Massimiliano Allegri's stint ended in 2024, tapping into the collective psyche and massaging a few egos would seem the be the easy part of his new role.
Turning a flat and often predictable group of players into something approaching a cohesive unit that's solid at the back and lightning fast in their transitions isn't something that's going to happen overnight.
Trusting in the process and getting buy-in from his players is really all that Spalletti can ask for at this point, and Koopmeiners' willingness is an early win in this regard.
If performance levels and results show a positive upturn, then, injuries notwithstanding, the manager has proven he has the nous and capabilities to construct something special.
The pressure on him to deliver just that will be immense, of course, but he does have the players to realise his vision.
The question is, do they have the work ethic for what's needed and ahead of them over the next few months?
