Last season wasn't just historic—it was unprecedented. Bayer Leverkusen went 51 games unbeaten across all competitions, won the Bundesliga with 90 points (28W-6D-0L), lifted the DFB-Pokal, and reached the Europa League final. They became the first team to break Bayern Munich's stranglehold on German football since Borussia Dortmund in 2011-12.
Under Xabi Alonso, they didn't just win—they revolutionized how German football is played. Their high-intensity pressing, rapid transitions, and tactical flexibility made them the most exciting team in Europe. Florian Wirtz emerged as one of the continent's brightest talents. Granit Xhaka reinvented himself as a deep-lying playmaker. Jeremie Frimpong became the Bundesliga's most dangerous wing-back.
Now comes the truly difficult part: defending the title.
## The Unbeaten Season: What Made It Possible
To understand the challenge ahead, we need to understand what made last season so special.
**Tactical Innovation**
Alonso's 3-4-2-1 system was perfectly calibrated for the Bundesliga. The three center-backs (Tah, Tapsoba, Hincapié) provided defensive stability while enabling aggressive wing-backs. Xhaka dropped deep to form a back three in possession, allowing Palacios to push forward. The two attacking midfielders (Wirtz and Hofmann) had freedom to roam, creating overloads in dangerous areas.
The key was the transition speed. Leverkusen averaged just 8.3 seconds from winning possession to creating a shot—the fastest in Europe's top five leagues. Their counter-pressing was relentless: they won the ball back within 5 seconds of losing it 32% of the time, compared to the Bundesliga average of 19%.
**Individual Brilliance**
- **Florian Wirtz**: 18 goals, 20 assists across all competitions. His 0.89 xG+xA per 90 was the highest in the Bundesliga
- **Victor Boniface**: 21 goals in 28 league appearances, with an elite conversion rate of 24.7%
- **Granit Xhaka**: Completed 91.3% of his passes, the highest for any midfielder with 2,500+ passes
- **Jeremie Frimpong**: 14 goals and 12 assists from wing-back, a position that typically produces 3-5 goal contributions
**The Intangibles**
Championship teams need luck. Leverkusen had it. They scored 17 goals after the 80th minute—more than any other Bundesliga team. They won 11 games by a single goal. Their injury record was remarkably clean: only 127 days lost to injury for the entire squad, compared to Bayern's 312 and Dortmund's 289.
## Tactical Evolution: How Teams Have Adapted
The Bundesliga has learned. Opponents no longer press Leverkusen high—they've seen what happens when you leave space in behind. Instead, they've adopted a more pragmatic approach.
**The New Defensive Blueprint**
Teams now deploy a 5-4-1 or 5-3-2 against Leverkusen, sitting in a mid-block around the edge of their own box. They concede possession (Leverkusen's average possession this season is 64.7%, up from 58.3% last year) but deny the vertical passing lanes that powered their counter-attacks.
The numbers tell the story:
- Leverkusen's average shot distance has increased from 14.2m to 16.8m
- Their big chance creation rate has dropped from 3.2 per game to 2.4
- They're facing an average of 8.3 players in the defensive third when they enter the final third, up from 6.7 last season
**Alonso's Counter-Adjustments**
To his credit, Alonso has adapted. Leverkusen now:
- Use more patient build-up play, probing for weaknesses rather than forcing vertical passes
- Rotate Wirtz and Hofmann into wider positions to stretch compact defenses
- Employ more set-piece variations (they've scored 14 goals from set pieces this season vs. 9 last year)
- Utilize Xhaka's long-range passing to switch play and create overloads
But adaptation takes time. In the first half of this season, Leverkusen have drawn 8 games—already two more than all of last season. They're still creating chances (2.1 xG per game vs. 2.3 last season), but converting them has been harder against packed defenses.
## The Numbers Behind the Challenge
Let's examine the underlying metrics:
**Attacking Output**
- Goals per game: 2.4 (down from 2.8)
- xG per game: 2.1 (down from 2.3)
- Shot conversion rate: 15.2% (down from 18.7%)
- Progressive passes into the final third: 48.3 per game (up from 43.1)
The attacking numbers show a team still creating quality chances but struggling slightly with efficiency. The increase in progressive passes suggests they're working harder to break down defenses.
**Defensive Stability**
- Goals conceded per game: 1.1 (up from 0.8)
- xG against per game: 1.0 (up from 0.7)
- PPDA (Passes Allowed Per Defensive Action): 8.9 (up from 7.2)
- High turnovers leading to shots: 1.8 per game (down from 2.6)
The defensive metrics reveal the real challenge. Teams sitting deeper means fewer opportunities for high turnovers. When opponents do break, they're more dangerous because Leverkusen's defensive line is higher and more exposed.
**The Fatigue Factor**
Leverkusen have played 47 games this season across four competitions. Last season's unbeaten run meant they played deep into every tournament. The physical toll is evident:
- Average distance covered per game: 112.3km (down from 116.8km)
- High-intensity runs per game: 187 (down from 203)
- Sprint speed in the final 15 minutes: 28.4 km/h average (down from 29.7 km/h)
These marginal decreases compound over a season. Fresh legs make the difference in tight games.
## Squad Depth: The Achilles Heel
This is where Leverkusen's title defense becomes most vulnerable.
**The First XI vs. The Squad**
When Alonso can field his preferred starting eleven, Leverkusen are still elite. They've won 18 of 21 games with a fully fit squad, averaging 2.7 goals per game and conceding just 0.6.
But injuries have been more frequent this season:
- Boniface: 8 games missed (hamstring, ankle)
- Tapsoba: 6 games missed (thigh injury)
- Hofmann: 5 games missed (knee)
- Hincapié: 4 games missed (muscle strain)
When three or more key players are absent, Leverkusen's record drops dramatically: 3W-4D-2L. The drop-off in quality is stark.
**Depth Comparison**
| Position | Starter | Backup | Quality Gap |
|----------|---------|--------|-------------|
| ST | Boniface | Schick | Moderate |
| CAM | Wirtz | Adli | Significant |
| CM | Xhaka | Andrich | Moderate |
| WB | Frimpong | Stanisic | Significant |
| CB | Tah | Kossounou | Minimal |
Bayern Munich, by contrast, can rotate 5-6 players without significant quality loss. Dortmund's young squad has energy and depth. Leverkusen's bench simply isn't as strong.
**The January Window**
Leverkusen didn't reinforce significantly in January, adding only a backup left-back and a young midfielder from their academy. Financial Fair Play constraints and the club's philosophy of developing talent rather than buying established stars limited their options.
This conservative approach may prove costly in a season where squad depth could determine the title.
## Xabi Alonso: The Irreplaceable Factor
If there's one reason to believe Leverkusen can defend the title, it's the man in the dugout.
**Tactical Mastery**
Alonso's in-game management is exceptional. His average time to make a first substitution is 58 minutes—earlier than most Bundesliga managers—and his substitutions have directly led to 11 goals this season. He reads games brilliantly, identifying weaknesses and exploiting them.
His tactical flexibility is rare. Leverkusen have used seven different formations this season, seamlessly switching between systems based on the opponent. Against Bayern's high press, they used a 4-2-3-1 to create numerical superiority in midfield. Against Dortmund's counter-attacking setup, they employed a 3-5-2 to control possession.
**Man Management**
Players speak glowingly about Alonso's leadership. Xhaka, who had a difficult final season at Arsenal, credits Alonso with revitalizing his career. Wirtz has developed into one of Europe's elite talents under his guidance. Even fringe players like Adli and Stanisic have improved significantly.
The squad's cohesion is evident. They've come from behind to win 9 games this season—a sign of mental resilience that comes from strong leadership.
**The Elephant in the Room**
But Alonso's success has made him one of the most sought-after managers in world football. Real Madrid want him to replace Carlo Ancelotti. Liverpool are monitoring him as a potential Jürgen Klopp successor. Even Bayern Munich have reportedly made discreet inquiries.
Alonso has repeatedly stated his commitment to Leverkusen, but the speculation is constant. Does it affect the players? Does it create uncertainty? These are intangibles that don't show up in xG models but can influence a title race.
If Alonso leaves in the summer—or even mid-season if a truly elite opportunity arises—Leverkusen's title defense becomes exponentially harder.
## The Competition: Bayern, Dortmund, and Dark Horses
**Bayern Munich: The Wounded Giant**
Bayern spent €150M in the summer, bringing in Harry Kane, Kim Min-jae, and Konrad Laimer. On paper, they're stronger. In practice, they've been inconsistent.
Thomas Tuchel's tactical approach hasn't fully clicked. They've lost 4 league games already—as many as they lost in the previous two seasons combined. Their defensive record (1.2 goals conceded per game) is their worst in a decade.
But they're still Bayern. They have the best striker in the world in Kane (28 goals in 29 games). They have depth Leverkusen can't match. And they have a winning mentality forged over 11 consecutive titles.
Current position: 2nd, 3 points behind Leverkusen with a game in hand.
**Borussia Dortmund: The Young Pretenders**
Dortmund have the most exciting young squad in Germany. Karim Adeyemi, Jamie Bynoe-Gittens, and Youssoufa Moukoko form a devastating attacking trio. Their average age (23.7 years) is the lowest in the Bundesliga.
But youth brings inconsistency. They've beaten Bayern 4-0 and lost to Augsburg 3-1 in the same month. Their defensive fragility (1.4 goals conceded per game) makes them vulnerable in tight title races.
Current position: 3rd, 5 points behind Leverkusen.
**VfB Stuttgart: The Dark Horse**
Stuttgart have been the surprise of the season. Sebastian Hoeneß has built a high-pressing, high-scoring team that plays fearless football. Serhou Guirassy has 24 goals—second only to Kane.
But their squad depth is even thinner than Leverkusen's. They're competing in the Champions League for the first time in years, and the fixture congestion is showing. They've won just 2 of their last 8 games.
Current position: 4th, 8 points behind Leverkusen.
## Can They Defend the Title?
The data suggests Leverkusen are in a genuine title race, but they're no longer favorites.
**Factors in Their Favor:**
- Xabi Alonso's tactical brilliance
- Florian Wirtz's world-class form (16 goals, 14 assists this season)
- Strong underlying metrics (2.1 xG per game, 1.0 xG against)
- Mental resilience (9 comeback wins)
- Home form (13W-2D-0L at the BayArena)
**Factors Against Them:**
- Squad depth limitations
- Increased injury frequency
- Opponents' tactical adaptations
- Physical fatigue from last season's long campaign
- Alonso's uncertain future
**The Prediction**
Going unbeaten again is virtually impossible—no team has done it in consecutive seasons in any major European league. But winning the title? It's a coin flip.
If Leverkusen can keep their key players fit and Alonso stays focused, they have a 45-50% chance of defending the title. Bayern's inconsistency and Dortmund's youth give them an opening.
The next eight weeks are crucial. Leverkusen face Bayern (away), Dortmund (home), and Stuttgart (away) in a brutal stretch. Win two of those three, and they're in the driver's seat. Lose two, and the psychological advantage shifts to Bayern.
here's the deal: the Bundesliga title race is the most competitive it's been in 15 years. And that's partly because of what Leverkusen proved last season—you don't need to be Bayern to win in Germany.
That genie is out of the bottle now. The question is whether Leverkusen can ride it for one more season.

## FAQ
**Q: What was Bayer Leverkusen's record in their unbeaten season?**
A: Leverkusen went 51 games unbeaten across all competitions in 2024-25, including a perfect 28W-6D-0L record in the Bundesliga. They won the league with 90 points and also lifted the DFB-Pokal. The unbeaten run finally ended in the Europa League final against Atalanta (3-0 loss).
**Q: How has Xabi Alonso's tactical system evolved this season?**
A: While maintaining his core 3-4-2-1 formation, Alonso has adapted to opponents sitting deeper by: (1) using more patient build-up play, (2) rotating attacking midfielders wider to stretch defenses, (3) increasing set-piece variations, and (4) utilizing Xhaka's long-range passing to switch play. The team has also employed seven different formations this season depending on the opponent.
**Q: What is Leverkusen's biggest weakness in defending the title?**
A: Squad depth is the critical vulnerability. When the full starting XI is available, Leverkusen have won 18 of 21 games. But with 3+ key players absent, their record drops to 3W-4D-2L. Unlike Bayern Munich, who can rotate 5-6 players without quality loss, Leverkusen's backup options represent significant downgrades in key positions like attacking midfield and wing-back.
**Q: How have Bundesliga teams adapted to playing against Leverkusen?**
A: Opponents now deploy deeper defensive blocks (typically 5-4-1 or 5-3-2), sitting in a mid-block rather than pressing high. This denies the vertical passing lanes that powered Leverkusen's counter-attacks. As a result, Leverkusen's average shot distance has increased from 14.2m to 16.8m, and they're facing an average of 8.3 players in the defensive third (up from 6.7 last season).
**Q: Will Xabi Alonso leave Leverkusen this season?**
A: While Alonso has repeatedly stated his commitment to Leverkusen, he's been linked with Real Madrid, Liverpool, and Bayern Munich. The speculation is constant, though there's no indication he'll leave mid-season. The summer is more uncertain, especially if Real Madrid or another elite club makes a formal approach. His potential departure is the biggest threat to Leverkusen's long-term success.
**Q: How does Bayern Munich compare to Leverkusen this season?**
A: Bayern spent €150M in the summer and have superior squad depth, but they've been inconsistent under Thomas Tuchel, losing 4 league games already. Harry Kane has been exceptional (28 goals in 29 games), but their defensive record (1.2 goals conceded per game) is their worst in a decade. They're currently 2nd, 3 points behind Leverkusen with a game in hand, making them slight favorites for the title.
**Q: What are Leverkusen's chances of winning the title?**
A: Based on current form, underlying metrics, and remaining fixtures, Leverkusen have approximately a 45-50% chance of defending the title. The next eight weeks are crucial, with matches against Bayern (away), Dortmund (home), and Stuttgart (away). Winning two of those three would significantly improve their chances. The title race is the most competitive in 15 years, with Bayern's inconsistency and Dortmund's youth creating opportunities for Leverkusen.
