Bayern Munich were narrow 1-0 winners over Pep Guardiola's Manchester City on Wednesday evening with 20-year-old debutant Erdal Ozturk on the scoresheet.
Here are five things we learned from Carlo Ancelotti's first home game in charge of the Bavarian giants.
1. Carletto's Way
"If it ain't broke don't fix it," remains the old adage. During his early media sparring in Munich, Ancelotti has been at pains to stress that he will not tinker too much with Guardiola's passing style. "I'm not here to start a revolution," the 57-year-old revealed at his recent unveiling as Bayern coach.
"Guardiola's style at Bayern was very nice and good. I hope that the players don't forget this," Ancelotti added ahead of the prestigious preseason friendly against City.
"Guardiola's work here over the past three years will also be important for this season," he emphasised.
2. Carlo's Catenaccio
With Bayern currently bereft of 11 holidaying Copa America and Euro 2016 stars, it's hard to read too much into the City game's offerings from a Bayern B team perspective.
Only skipper Philipp Lahm and David Alaba were guaranteed starters in Wednesday's makeshift starting XI. However, on the evidence of Ancelotti's trophied career so far, whether at Chelsea, AC Milan or more recently at Real Madrid, he'll likely adopt more defensive tactics, especially on the European stage -- similar perhaps to Jupp Heynckes' solid and spectacularly successful, 2013 treble-winning side.
Interestingly, when announcing Guardiola's successor in December, club chairman Karl-Heinz Rummenigge explained: "Carlo's a calm, balanced and proven expert, who knows how to deal with stars and favours a multifaceted playing style -- this is what we were looking for and this is what we've got."
In hindsight, the more malicious Bayern fans might consider that "multifaceted style" comment by Rummenigge as a sly dig at Guardiola, especially after falling short in three consecutive Champions League semifinals against Spanish sides. For all the delightful and often mesmerising passing football, you'd have to say Guardiola's Bayern were a little predictable and naive against the counter-attack when it really mattered most in the European elite.
Fine-tuning will begin in earnest when the luxury of riches trickle back from their well-deserved holidays early next month. Ancelotti is sure to address defensive frailties, but it's already a bonus to have kept a clean sheet on his first outing in Munich, even when down to the "bare bones" of the squad.
3. Don't throw away Gotze shirts just yet
Even if 24-year-old Mario Gotze's days are said to be numbered in Bavaria, at least his younger brother Felix still has a burgeoning future at the club. While his more famous brother continues to mull over a possible return to Westphalia, the 18-year-old central defender -- like Mario a former Borussia Dortmund player -- has impressed with two composed performances in Bayern's friendly in Lippstadt (4-3 winners) on Saturday and as a substitute against City.
With the likes of Holger Badstuber, Mats Hummels and Jerome Boateng either injured or on Euro vacation, there's sure to be more game time for Felix on the forthcoming tour of the United States. Felix, the youngest of the Gotze brothers (lest we forget 26-year-old Fabian), has gone under the radar so far during his career.
4. Too green
Julian Green, 21, was banished to the reserves under Guardiola and languished in the Regionalliga for almost the whole of last season, playing in only a single low-key Champions League fixture in Zagreb. But the US international forward has started both games under Ancelotti and scored in the 4-3 win in Lippstadt on Saturday. He had the chance to open the scoring in this game but found City keeper Willy Caballero in inspired form. However, Green's two glaring misses in the first half will not have improved his case for a first-team recall, especially when the likes of Robert Lewandowski and Thomas Muller return.
5. Touchline harmony
We know it will be a much quieter and more relaxed Bayern coach on the sidelines this season. Ancelotti will always remain in his coaching area for a start. It was never quiet on the Bayern bench during Pep Guardiola's tenure. The Catalan spent three lively seasons at Bayern patrolling his touchline -- gesticulating, tinkering, remonstrating, even offering titbits of advice to his skipper on a scrap of paper. Pep was normally clad in a suit or slim-fit dress shirt and/or fashionable men's jumper, even famously splitting his trousers on occasion due to over exuberance on the touchline.
You just cannot see the lower-intensity Ancelotti getting his feathers ruffled so much by events unfolding in front of him. Ancelotti seems to be comfortable in a club tracksuit, hands behind his back, watching his side at peace with the world. At times, it looks like it will be an effort for the laid-back 57-year-old to change that stick of chewing gum or raise a bushy eyebrow.
