The Defining Moment
Eintracht Frankfurt’s defensive unit entered 2026/27 as the department most urgently in need of reconstruction. The previous campaign had ended with 65 goals conceded—the third-worst record in the Bundesliga—and the summer departures of Nathaniel Brown to Bayern Munich for €55 million and Rasmus Kristensen to his homeland had stripped the back line of its two most reliable wide defenders . Sporting director Markus Krösche acted to address the crisis, bringing in Lilian Brassier from Rennes and the young Brazilian Otávio from Estrela Amadora, while Keita Kosugi was promoted from the winter signing to a first-team role .
The defining characteristic of the season has been the persistence of the same vulnerability that defined the previous campaign. By November, Kicker was blunt in its assessment: “The defensive wide areas remain Frankfurt’s Achilles’ heel” . The experiment of deploying Ansgar Knauff, a natural attacker, at right-back lasted 45 minutes before he was substituted with dizziness after a clash of heads. Nnamdi Collins, his replacement, was immediately exposed by Paderborn’s attackers. With Elias Baum suspended after a yellow-red card, Hütter was forced to consider a return to a three-man defence simply to cover the gaps .
This is the story of Frankfurt’s 2026/27 defenders: a captain carrying the burden of a rebuilt back line, a young German full-back thrust into a role he may not be ready for, and a unit that remains the club’s most obvious weakness.
Tactical Context
Adi Hütter’s return to Frankfurt brought a shift in defensive structure. The Austrian’s preferred approach is built on intensity and aggressive pressing, with a high defensive line that demands mobility and recovery pace from the centre-backs. His previous tenure at the club was defined by a three-man defence with offensive wing-backs, and the personnel available have forced him to consider a return to that system .
The early-season numbers reflect a defence under strain. In their opening six Bundesliga matches, Frankfurt conceded 16 goals—a rate of 2.67 per game—and kept just one clean sheet . Their pressing intensity, measured by PPDA, was the second-lowest in the division at 12.0, suggesting a team that was either unwilling or unable to press effectively, leaving the defence exposed to sustained pressure . The 6-0 defeat at RB Leipzig, in which the back line was comprehensively dismantled, was the low point of the opening phase .
The tactical question for Hütter is whether his personnel can execute his preferred system. Robin Koch, the captain, is a reliable centre-back but lacks the recovery pace to defend large spaces. Brassier has been the most consistent of the new arrivals, but the full-back positions remain unresolved. Baum is a natural right-back but has been deployed on the left out of necessity. Kosugi, the Japanese left-back, has shown promise going forward but remains defensively vulnerable .
The Defenders
Robin Koch
Koch is Frankfurt’s captain, its most experienced defender, and the player upon whom the back line depends. The 30-year-old German international has started all eleven of Frankfurt’s competitive matches this season, accumulating 925 minutes and contributing two goals and one assist . His leadership and experience are invaluable in a unit that has been repeatedly reshuffled.
His profile suits a possession-based approach: Koch is comfortable on the ball, positionally disciplined, and capable of stepping into midfield to initiate attacks. But the previous campaign exposed his limitations when asked to defend large spaces, and the departures of Brown and Kristensen have left him with less protection than ever . At 30, he remains the foundation upon which Hütter must build, but the structure around him requires urgent reinforcement.
Lilian Brassier
Brassier has been the most successful of Frankfurt’s summer defensive signings. The 27-year-old Frenchman arrived from Rennes and has started eight matches, accumulating 720 minutes and contributing one assist . His physical profile—strong in duels, composed in possession, and aggressive in the tackle—offers a complementary presence alongside Koch.
At his best, Brassier provides the defensive solidity that Frankfurt lacked in the previous campaign. His partnership with Koch has shown promise in patches, but the instability at full-back has prevented the back line from developing the cohesion that Hütter’s system requires. An injury to Brassier would leave Frankfurt dangerously thin at centre-back, a concern that Kicker identified as requiring January reinforcement .
Elias Baum
Baum is the young full-back thrust into a role of unexpected importance. The 21-year-old German has started eleven matches, accumulating 750 minutes and contributing one goal and one assist . His natural position is right-back, but the departure of Brown and the absence of a specialist left-back have forced Hütter to deploy him on the left.
His profile is that of a modern full-back: energetic, comfortable carrying the ball forward, and capable of delivering quality crosses. But his defensive positioning remains a work in progress, and his suspension after a yellow-red card against Paderborn exposed the lack of depth behind him . At 21, Baum has time to develop, but the demands of a Bundesliga season are unforgiving for a player still learning his trade.
Keita Kosugi
Kosugi is the Japanese left-back signed in January 2026 as a potential successor to Brown. The 20-year-old has started nine matches, accumulating 672 minutes and contributing three assists—a respectable return for a defender . His attacking thrust from left-back offers width in a team that has often lacked it.
The concern is defensive. Kosugi has been described as “too inconsistent” and was dropped after a poor performance, only to be recalled when Baum was suspended . At 20, he remains a work in progress, and Hütter’s consideration of a three-man defence may be partly designed to provide him with additional cover.
Nnamdi Collins
Collins is the young centre-back whose development has been disrupted by inconsistency. The 22-year-old German has made six appearances, accumulating 375 minutes . His recovery pace is the best among Frankfurt’s defenders, a quality that suits Hütter’s high line, but his positioning and decision-making have been exposed when deployed at full-back .
At 22, Collins has time to develop into a reliable centre-back. But the demands of a season in which Frankfurt are fighting for European qualification may not allow him the patience he requires.
Otávio
Otávio is the summer signing who has yet to justify his arrival. The 20-year-old Brazilian arrived from Estrela Amadora with a reputation as a promising left-footed centre-back, but his adaptation to the Bundesliga has been difficult. He has made just two appearances, accumulating 95 minutes, and Kicker’s assessment was blunt: “Otávio has so far completely flopped” .
At 20, Otávio retains the potential that persuaded Frankfurt to invest in him. But the immediate demands of the season require a level of readiness that he has not yet demonstrated.

Tactical Identity & Squad Balance
Frankfurt’s defensive unit is a reconstruction that remains incomplete. The summer departures of Brown and Kristensen removed the two most reliable wide defenders from a back line that had already conceded 65 goals in the previous campaign . The arrivals of Brassier and Otávio addressed the centre-back positions, but the full-back roles remain unresolved.
Kicker’s assessment in November was unequivocal: Frankfurt must reinforce in the winter transfer window, with a right-back and a left-sided centre-back identified as priorities . The club’s new sporting director, Joti Chatzialexiou, is expected to arrive before the window opens, and his first task will be to address the defensive gaps that have defined the season.
The concern is not individual quality but collective cohesion. Koch and Brassier form a competent centre-back partnership, but the full-backs are either inexperienced (Baum, Kosugi) or playing out of position (Knauff, Collins). Hütter’s consideration of a three-man defence is a recognition that the current structure leaves the back line exposed, particularly in wide areas.
The Verdict from the Camp
Kicker on Frankfurt’s defensive priorities:
“In the winter transfer window, Eintracht must urgently reinforce in defence. In Paderborn it became clear once again where the shoe pinches. Due to the absence of Elias Baum, the question arises whether coach Adi Hütter will return to a three-man chain.”
Kicker on Otávio’s struggles:
“The signing of a left centre-back also seems sensible, as Otávio has so far completely flopped. An absence of Lilian Brassier could not be compensated for over a longer period.”
Robin Koch on the defensive rebuild:
“We are losing quality and mentality with Brown and Kristensen. As a defender, you wish you had the boys together relatively quickly and could prepare together.”
Where Next?
Frankfurt’s defensive priority for 2026/27 is urgent reinforcement. The January window represents the club’s best opportunity to address the full-back positions that have been exposed throughout the season. A right-back and a left-sided centre-back have been identified as the minimum requirements, with Chatzialexiou’s arrival expected to accelerate the process .
The longer-term question is whether Hütter can forge a cohesive unit from the players available. Koch and Brassier provide a foundation, but the full-backs require either development or replacement. Baum and Kosugi have potential but are not yet reliable starters at this level. Otávio’s adaptation remains incomplete.
For now, the focus is on the next match and the next defensive performance. Frankfurt’s record of 1.75 goals conceded per game is mid-table, but the underlying numbers—the passive pressing, the low save percentage, the 6-0 defeat to Leipzig—suggest a defence that remains vulnerable . If the January window brings the reinforcements that Kicker has identified as essential, Hütter’s back line may yet stabilize. If not, the Achilles’ heel that has defined Frankfurt’s season will continue to be exploited.
