On the 9th October, with the club in disarray, Jupp Heynckes returned for his third full-time stint at Bayern Munich.
The German came out of retirement after winning a first-ever treble with the Bavarians in 2013.
Carlo Ancelotti's tenure in the south of Germany was largely considered a failure as the club were bested by his former side Real Madrid in the Champions League and knocked out of the DFB-Pokal semis by Borussia Dortmund.
The Italian was accused of mismanagement and losing the dressing room with several stars visibly irked nearing the end of his tenure. A poor start to the season and a hammering at the hands of Paris Saint-Germain sent Ancelotti on his way.
In came club legend Heynckes, who immediately looked to turn things. After being well adrift of Borussia Dortmund early on, Bayern have gone into resurgent mode and cleared a six-point lead at the summit, as things return to the status quo.
Here are five players in particular who have benefited from the prodigal son's return...
5. David Alaba
A product of die Roten's illustrious youth academy, David Alaba has all the talent to become one of the finest left-banks of this century. But he has regressed from mismanagement at the hands of Ancelotti and Pep Guardiola; though the latter's reasons were justified.
The Austrian international was limited in attacking due to Ancelotti causing a notable gap between the defence and midfield. Now though, Alaba has been putting in some excellent shifts as he looks to get back to his golden years under Heynckes.
The only blip in the 25-year-old's displays of late came in his last match, where Kylian Mbappe glided past his marker - and other defenders - with relative ease, but good times are ahead.
4. James Rodriguez
Replaced and forced out under the new regime of Zinedine Zidane at Real Madrid, James Rodriguez had to look to Germany for getting his career back on track. He's done just that.
An ineffective half at the Parc des Princes before Ancelotti's sacking typified how far the Colombian had fallen from grace since his excellent World Cup in 2014.
Rodriguez though showed what he was capable of in the crunch tie against Dortmund at the Westfalenstadion, being instrumental in the win with two finely tuned assists.
3. Kingsley Coman
A sensational start to life at Bayern began to fade last season, but despite his youth, Kingsley Coman has had the maturity to pick himself up and return to form again.
In interim coach Willy Sagnol's only match in charge, Coman looked bereft of sharpness even against a poor Hertha BSC side. But during Heynckes' first game, the former Juventus man looked revitalised, putting in an excellent performance against SC Freiburg.
Since the match against Freiburg, Coman already has three goals and three assist to his name in nine matches.
2. Corentin Tolisso
Just like his fellow countryman, Corentin Tolisso has excelled since Heynckes' changes. The midfielder looked out of his depth with the pressure of being the most expensive player in Bayern's history seemingly weighing him down.
However, confidence now seems to be running through his veins yet again, as the former Olympique Lyonnais player is getting better with every game. His first start under the returning manager was a stellar performance against Hamburger SV, but his best performance in a red shirt was against PSG on Tuesday night, scoring two decisive goals against his old nemesis.
Eager to continue his form, Tolisso will be looking to start against a winless FC Koln side at the weekend.
1. Sven Ulreich
Understandably, it is no easy job to follow the tremendous act of Manuel Neuer in goal, but Sven Ulreich has certainly done well of late.
After two uneventful seasons, the former Stuttgart player has been called into action for most of the season on account of an injury to the number one. While his initial performances left much to be desired, Ulreich has since transformed into a wall.
Though being robbed of some clean sheets due to a lapse in defending, Ulreich's reactions above all have sharpened immensely and he even managed to get an assist in the win over Celtic.
