Leverkusen Faces Midfield Challenges After Eichhorn's Health Setback

Bayer Leverkusen’s carefully drawn blueprint for the new season has been jolted by a stark and unexpected reality: Kennet Eichhorn, the 17-year-old signed to be a cornerstone of the club’s future, is facing a long spell out with a serious metabolic illness.

What began as a routine pre-season setback has turned into something far more troubling. In mid-July, Eichhorn lost five kilos in five days due to a gastrointestinal infection. That dramatic weight loss triggered further medical checks. The diagnosis that followed has forced Leverkusen to rethink not just their short-term options, but the pace at which one of Europe’s most coveted young midfielders can be integrated into elite football.

Eichhorn is now in inpatient treatment, where doctors are working to uncover the causes of the condition and rebuild his strength. For the club, the message from the medical department is clear: patience, not pressure.

No timetable, no guarantees

There is currently no return date on the table. According to Sport Bild, Leverkusen expect a lengthy absence and have removed Eichhorn from their squad planning for the entire first half of the season. The club will not rush a teenager whose health now comes before any tactical plan or transfer calculation.

For a player who arrived with such fanfare, the contrast is stark. Only weeks ago, Eichhorn was being talked about as one of the standout prospects of his generation. Now the priority is simply getting him healthy.

A market reshaped in midfield

His situation has immediate consequences for the rest of Leverkusen’s midfield. The original idea had been bold: sell two central midfielders to clear space and fund further moves. That strategy has been quietly shelved. With Eichhorn unavailable, only one central midfielder is now expected to leave.

• Equi Fernandez (24)
• Aleix Garcia (29)
• Robert Andrich (31)

Fernandez, by all accounts, is the one with the biggest market. The 24-year-old could fetch around 20 million euros, a significant sum for a player whose Leverkusen story has already taken a few twists. He had fallen out with former coach Kasper Hjulmand, a rift that cast doubt on his long-term future. Under Carles Martinez, that tension has eased. The relationship is now described as intact, which complicates the decision. Selling your most marketable midfielder is easier on paper than in a dressing room that has just lost a key young option for months.

Garcia’s situation is different. The 29-year-old can imagine a move and is open to a new challenge, but the market has not yet answered. Suitable offers are said to be lacking, leaving him in a kind of transfer limbo: willing to go, but with no clear door to walk through.

That leaves Andrich. At 31, he represents experience, stability, and a known quantity in the Bundesliga. As things stand, everything points to him staying. In a summer that was supposed to be about renewal and generational change, the veteran may end up more important than anyone at the club anticipated when the window opened.

From Hertha breakthrough to brutal pause

The timing of Eichhorn’s setback is particularly cruel because of the trajectory he had carved out last season. At Hertha BSC in the 2. Bundesliga, he did more than just flash potential; he established himself as a regular. He navigated the rough edges of a long campaign, missing time only through an ankle injury and a suspension after a red card. Those bumps are almost a rite of passage for a young midfielder learning to impose himself.

His performances did not go unnoticed. Scouts from across Europe circled. Bayern Munich, Liverpool, Manchester City, Real Madrid and Paris Saint-Germain all registered interest. For a teenager operating outside the top flight, that level of attention underlined how highly he was rated.

Leverkusen moved decisively. They paid nine million euros to bring him in, a clear statement that they saw Eichhorn not as a project for the distant future, but as a player who could soon compete for serious minutes in a squad chasing trophies on multiple fronts.

Now that momentum has been abruptly halted.

An open future

The question hanging over Leverkusen is not about Eichhorn’s talent. That remains unquestioned. It is about time. How long will it take for him to recover, rebuild his body, and then re-adapt to the intensity of top-level football?

For now, there are no answers. There is only an acceptance that the club must wait, that the midfield hierarchy will be shaped by Fernandez’s market, Garcia’s suitors, and Andrich’s reliability, while the most intriguing new signing watches from a hospital bed instead of the training pitch.

Eichhorn moved to Leverkusen to make a breakthrough on the big stage. When that moment will come is completely open – and that uncertainty now hangs over a season that was supposed to showcase one of Europe’s brightest young midfielders.
