Julian Nagelsmann has long seemed destined to be Bayern Munich coach, and the 34-year-old now has his chance after succeeding Hansi Flick.
He has a lot to live up to. Flick, in his 18-month tenure, Flick led Bayern to two Bundesliga titles, one DFB-Pokal, a Champions League triumph, Club World Cup glory, the DFL-Supercup and the UEFA Super Cup – a remarkable seven trophies.
While Nagelsmann settles into life in the hottest of coaching seats in Germany, his former team RB Leipzig will look to finally make a title challenge last, this time under new coach Jesse Marsch.
Borussia Dortmund scraped into the Champions League places thanks to a super run late in the season, and now Marco Rose will look to build on their DFB-Pokal success in his first season in charge.
Just what can we expect from each of Germany's big three in 2021-22?
Bayern Munich
Bayern ultimately claimed their ninth successive Bundesliga title with ease last term and Robert Lewandowski was once again the driving force. He had to wait until the last kick of the last day, but he finally broke Gerd Muller's long-standing Bundesliga record of 41 goals in a single campaign.
Unsurprisingly, Bayern scored the most goals in Germany's top tier in 2020-21, netting 99 times across their 34 fixtures. Their tally of 483 chances was also by far the most in the division, 54 ahead of second-ranked Leipzig (429) in that regard, though they conceded 44 times while the Leipzig defence under Nagelsmann was the stingiest, with only 32 goals conceded.
Bayern averaged 65.39 per cent possession and had 1,304 touches in the opposition box, over 400 more than any other side.
However, Nagelsmann does have to contend with the loss of some players who have been crucial to Bayern's dominance. David Alaba has joined Real Madrid, while fellow stalwarts Javi Martinez and Jerome Boateng also left on free transfers.
Dayot Upamecano has made the same switch from Leipzig as Nagelsmann, and the young centre-back adds pace and dynamism to Bayern's backline. Other than that, the squad remains largely the same, with Sven Ulreich having returned after a spell at Hamburg, while Omar Richards arrived on a free transfer from Reading.
Even without much more in the way of incomings, it is difficult to see Bayern letting the chance to make it 10 titles in a row slip from their grasp.
Dortmund
Last season was a difficult campaign for Dortmund, but it was one which ultimately ended successfully. They clinched Champions League qualification and ran riot against Leipzig to lift the DFB-Pokal.
It was a fine parting gift from Edin Terzic, who took over on an interim basis after Lucien Favre was relieved of his duties, and now Rose – whose Borussia Monchengladbach team slumped in the back half of the season and missed out on Europe – will look to reshape Dortmund in his own way.
Renowned for attacking, front-foot football, Rose's style, if all goes to plan, is bound to be a hit with the Dortmund fans upon their return to Signal Iduna Park.
Dortmund may have sold Jadon Sancho, but they still have Norway sensation Erling Haaland, who scored 27 Bundesliga goals last season from 93 attempts, giving him a shot conversion rate of 29.03 per cent, the third-highest in the league out of players to have scored 10 or more times.
Donyell Malen has arrived as Sancho's replacement, and Rose has already been talking up the Netherlands youngster, while goalkeeper Gregor Kobel has arrived from Stuttgart. Like Bayern, Dortmund said goodbye to a club legend in the form of Lukasz Piszczek, but with Marco Reus, Thorgan Hazard, Malen and Haaland complemented by the likes of Julian Brandt and Jude Bellingham, there should be plenty of cause for optimism.
It might well be Haaland's final season at the club, and you would not put it past the youngster, who also set up six goals last term, to propel Dortmund into the title race, back where they belong.
RB Leipzig
There are plenty of quality teams competing with the three leading lights, and it would certainly not be surprising to see Bayer Leverkusen, Wolfsburg, Eintracht Frankfurt or Gladbach mount a serious push for Champions League football.
However, Leipzig have well and truly established themselves as a Champions League regular now, and will be looking to Marsch, who has made the transition from sister club Salzburg, to continue Nagelsmann's work.
Leipzig sold Timo Werner to Chelsea in 2020, and netting just 60 times, they clearly missed the striker. Indeed, midfielder Marcel Sabitzer, with eight goals, was their leading scorer, with forwards Alexander Sorloth and Yussuf Poulsen only managing five each.
In Andre Silva, signed from Frankfurt, Leipzig have a forward who scored more than Haaland in the Bundesliga last season, with the Portugal international finding the net 28 times in 32 appearances.
Silva boasted an impressive 'big chance', as defined by Opta, conversion rate of 55 per cent, while only Lewandowski (137) had more than the former Milan man's 117 attempts. Dani Olmo and Christopher Nkunku – who supplied nine and six assists respectively last season – can provide the creativity, with Poulsen and Sorloth able to offer Marsch a variety of attacking options. Caden Clark, who is starring in MLS, will arrive before the turn of the year, while Dominik Szoboszlai is almost like a new signing, given he is yet to feature for the club since his arrival in January due to injury.
Leipzig have faced a reshuffle in what had been a strong defence, with key man Upamacano departing while Ibrahima Konate has also left for Liverpool, though the acquisition of Salzburg's highly rated Mohamed Simakan shows the production line is still ticking along, and a Champions League place will be the minimum expectation.
