That surprisingly came after a disappointing start to the season which saw Niko Kovac replaced by Hansi Flick, who has since taken the Bavarian side to another level.
Here, we lay out some predictions for the new top-flight German season.
After winning the treble last season, Bayern Munich might even be stronger in 2020-21 thanks to the addition of Leroy Sane.
Thiago looks set to leave, but Bayern are already planning without him and will partner Joshua Kimmich with Leon Goretzka in midfield as Hansi Flick looks to dominate German football again this year.
|Top Four||Dortmund, RB Leipzig, GLADBACH|
Borussia Dortmund - Keeping Jadon Sancho is key to Dortmund's season as he and the rest of their young attack have formed a brilliant connection. The return of Marco Reus from injury should also provide a boost.
RB Leipzig - The Red Bulls lost Timo Werner before the Champions League mini-tournament kicked off in Lisbon, but showed they could cope without him as they progressed to the semi-finals.
Borussia Monchengladbach - Like Dortmund, Gladbach benefit from retaining their key players this season. Clubs sniffed around some of their talent names, but Marco Rose's project is very exciting and helped the Foals keep hold of their big names.
|Relegated||MAINZ (PLAYOFF), ARMINIA BIELEFELD, AUGSBURG|
Arminia Bielefeld won the 2. Bundesliga last season but fellow promoted side Stuttgart look better capable of staying up this season. Mainz and Augsburg were less than impressive in 2019-20 and both have been weakened over the off-season. It will be a struggle for either team to stay in the top flight.
|Best Signing||LEROY SANE (Bayern)|
Bayern Munich have chased the German winger for a long time but finally got their man at the start of the summer.
They already boast one of Europe's best attacks and the trio of Serge Gnabry, Robert Lewandowski, and Sane could prove unstoppable.
|Worst Signing||ALEXANDER NUBEL(Bayern)|
As well as the best signing of the window, Bayern Munich have made the worst. Young goalkeeper Alexander Nubel has been thought of as the successor to Manuel Neuer, but after agreeing to join on a free transfer, lost his place in the Schalke team and caused a civil war at both Schalke and Bayern. Neuer will not sit back and allow the youngster to start ahead of him in any competition, so Bayern will end up with a well-paid unhappy backup.
|Top Goalscorer||Robert Lewandowski (Bayern)|
With Werner gone to Chelsea, Lewandowski's closest rival for the top scorer prize has left the league. The same thing happened a few years ago when Pierre-Emerick Aubameyang also moved to the Premier League. This trophy will have Lewandowski's name on it again and again for the next few years.
|Player of the Year||JOSHUA KIMMICH (Bayern)|
Thiago's absence will mean Leon Goretzka and Kimmich will have to step up in the Bayern midfield and Kimmich is starting to prove himself as one of the team's leaders.
He is much more effective in midfield than at right-back and will pull the strings as Bayern win another title.
|Surprise Package||WERDER BREMEN|
After narrowly avoiding relegation last season, Bremen will have a point to prove in 2020-21. The board kept faith in coach Florian Kohfeldt and it will prove to have been the right call as they will push for a European spot, even if they lose star winger Milot Rashica. Man Utd's Tahith Chong has arrived on loan and can provide the spark they need in attack.
|Breakout Star||JUDE BELLINGHAM (Dortmund)|
The teenage midfielder was so highly thought of at Birmingham, they retired his number. The Bundesliga and the Champions League will be a big step up from the Championship, but Bellingham has all the attributes to be Dortmund's next wonderkid sensation.
