Champions League 2025/26 · Round of 16
Bayer 04 Leverkusen, Rebuilt and Still Dangerous: The Werkself Story Before Arsenal
Bayer 04 Leverkusen is one of those teams you end up following even when you do not mean to. They play with an identity you can recognize, they build serious players, and for years they lived in that frustrating space between “very good” and “finally, truly elite.” Then they rewrote their own history in the most extreme way possible: by becoming invincible champions.
Now, in March 2026, they are back in the Champions League last 16, staring at the kind of draw that does not allow illusions. Arsenal are waiting. And if you have been watching Leverkusen closely, you already know why this matchup is so compelling: this is a club that has recently proven it can survive pressure, reinvention, and chaos, and still show up in Europe with a real punch.
This is the clean, structured story of who Bayer 04 Leverkusen are, how they got here, and what actually matters before the Round of 16.
The Identity: A “Works Team” That Became a Modern Power
Leverkusen’s origin story is not a romantic old-city club myth. It is industrial Germany, built by employees of the Bayer company. A workers’ letter asking for support led to the founding of the club in 1904, with a football department formed a few years later. The nickname “Werkself” (works team) is not branding. It is literal heritage.
That connection to Bayer is also why Leverkusen sit outside the usual German ownership logic. Germany’s 50+1 culture is designed to keep clubs member-controlled, but long-term corporate-backed clubs like Leverkusen are treated differently.
And the stage where all of this plays out is compact, intense, and unapologetically close to the action: the BayArena, a 30,210-capacity stadium that can feel tight enough to squeeze the game toward the opponent’s penalty box.

From “Almost” to Immortal: How Leverkusen Escaped Their Own Stereotype
For a long time, Leverkusen carried the weight of being the ultimate nearly-team. Strong squads, good coaches, big nights in Europe, and then the last step would collapse. The 2002 season became the symbol: Champions League finalists, but still second place in the moments that define reputations.
Then came the Xabi Alonso era, and it did not just bring improvement. It detonated the old narrative.
In 2023/24, Leverkusen became the first team to complete a full Bundesliga season unbeaten (28 wins, 6 draws), ending with 90 points. They also stretched an all-competitions unbeaten run into the 50+ match territory, a level that changes how Europe speaks about you.
If you want the shortest explanation of why Leverkusen now command respect, it is this: they did not “have a good season.” They produced a season that reclassified the club.

The Shockwave Summer: Why 2025 Forced a Rebuild
Great seasons often end with a tax: your best people become everyone else’s targets.
Leverkusen’s 2025 summer was exactly that. The headliner was Florian Wirtz leaving for Liverpool in a British-record type of deal, reportedly structured around a massive guaranteed fee plus add-ons.
Jeremie Frimpong also moved to Liverpool.
Jonathan Tah’s departure had been signaled publicly, and he ultimately completed a move to Bayern Munich.
Granit Xhaka pushed to return to England, with reporting around a Sunderland deal.
And the final piece was the one that hits club identity hardest: Alonso left the project, a storyline widely described at the time as the end of a once-in-a-generation cycle for Leverkusen.
When you lose a star creator, an elite outlet runner, a defensive leader, a senior midfield organizer, and the coach who made it all coherent, you are not “refreshing the squad.” You are rebuilding your operating system.
The Coaching Whiplash: Ten Hag Out, Hjulmand In
What followed was not a calm transition.
Erik ten Hag was hired after Alonso and then dismissed extremely early in the season, a decision that drew global attention largely because of how fast it happened.
Leverkusen then appointed Kasper Hjulmand on a contract running to June 2027. The club’s own announcement framed it as a decisive reset, and the Bundesliga’s coverage made clear this was a bet on a coach with both international-level management and Bundesliga familiarity (via Mainz).
The practical impact: Leverkusen have had to construct chemistry and match habits under time pressure, while still playing a calendar that punishes instability.

Where They Stand Right Now in the League
By early March 2026, Leverkusen are not running away with the Bundesliga like the invincible year. They are positioned in the European places race, sitting 6th on 44 points after 25 matches (goal difference +16 listed in common league summaries).
That matters for Champions League context because it signals a team that is competitive and organized, but not operating at the absolute domestic ceiling that 2023/24 represented.
Champions League Context: The Arsenal Test Is Real, and the Calendar Is Tight
The Round of 16 tie is confirmed as Bayer Leverkusen vs Arsenal, first leg at the BayArena on Wednesday, March 11, 2026, with the return leg on March 17, 2026.
Arsenal’s own ticketing page for the away leg has also treated this as a major demand fixture, which tells you what Leverkusen’s name now triggers across Europe: respect and caution.
This is where the emotional thread becomes honest: we like watching Leverkusen because they are never passive. Even when the squad changes, they tend to show up with intent. And now we get to see the rebuilt Werkself measured against arguably the most unforgiving kind of opponent: a top Premier League side that expects to control territory, tempo, and transitions.
What Leverkusen Can Realistically Lean On vs Arsenal
-
The BayArena Effect
Not every stadium creates pressure. The BayArena does, partly because of scale and proximity. It can turn a “normal” opening 20 minutes into a problem if the opponent is sloppy with buildup and second balls.
-
The Post-Invincible DNA
Even with departures, the club has recently lived through the highest-pressure environment imaginable: chasing perfection, carrying an unbeaten streak, and being the hunted every week. That experience changes how a squad approaches knockout football.
-
Hjulmand’s Structure-First Profile
Hjulmand’s reputation has long been tied to collective clarity: spacing, disciplined pressing cues, and a team that looks like it knows what it is trying to do. Leverkusen did not hire him to entertain. They hired him to stabilize and compete at elite speed.
Where the Tie Can Break Against Them
-
Rebuild Timing vs Arsenal’s Continuity
Arsenal are built to punish small coordination errors: half-second late rotations, midfield gaps, fullback timing mistakes. A rebuilt Leverkusen can be brave, but bravery becomes a liability if the distances are wrong.
-
The “New Leaders” Question
When Tah, Xhaka, and Alonso are gone, the leadership hierarchy has to be re-earned. ESPN’s reporting around the summer emphasized exactly that issue: maturity, grit, and composure do not replace themselves automatically.
-
Game State Discipline
Leverkusen’s best outcomes in Europe usually come when they manage game states like a veteran: when to accelerate, when to slow, when to accept an ugly five-minute stretch without conceding. Arsenal force you to prove you can do that twice.

Key Takeaways

- Summer 2025 ripped out core pillars (Wirtz, Frimpong, Tah, Xhaka, plus Alonso), forcing a true reset.
- The Ten Hag episode was short; Hjulmand is the long-term bet through 2027.
- Arsenal is a brutal Round of 16 draw, but Leverkusen are exactly the kind of team that can make a favorite feel uncomfortable in a two-leg tie.
