FC Köln facing profound upheaval: René Wagner shapes squad planning

With the decision for René Wagner, 1. FC Köln is associating more than just a change on the coaching bench. The club is aligning squad planning for the coming season with Wagner's ideas – and is reorganizing itself both in terms of personnel and structure after an internal analysis of the past season.

Wagner is 37 years old and, according to the club, took office in the spring. This marks the start of the next phase of a project in Cologne, which, after several coaching changes since 2021, is supposed to deliver above all one thing: a clearer sporting line that is not called into question again after just a few months. In the sporting management, the course is understood as a fresh start – less looking back, more planning for a team that fits a recognizable playing idea and the coach's requirements.

Why the decision for Wagner has immediate consequences

According to the club, the discussions before settling on Wagner were not just about personnel, but about the orientation of the team. CFO Philipp Türoff described the process as follows: “We sit down with René and no longer talk about the past season, but about the new one. What is René’s vision? What does he have in mind? What do we need? Based on that, we will then make a decision.”

This logic explains why the debate in Cologne is now less about individual players and more about role profiles: Who fits the football Wagner wants to play? Who brings the intensity and reliability that was identified as a problem area in the season analysis? According to EXPRESS.de, not only playing deficiencies but also questions of attitude within the squad were addressed. This also became visible at the end of the season in the last two results: Cologne lost 1:3 to Heidenheim and 1:5 at FC Bayern.

The club is thus trying not to organize the next upheaval merely as a reaction to results. Parallel to the coaching decision, Cologne has restructured its sporting leadership: Tim Steidten was appointed Director of Recruiting & Squad Planning in March. According to the club, squad planning is to be managed more centrally in the future – a signal that transfers and contract decisions should be made more according to plan and less under short-term pressure.

Confirmed departures – and what they say about the course

Some personnel decisions have already been made. Eric Martel is leaving 1. FC Köln and moving to 1. FSV Mainz 05; Mainz has officially confirmed the transfer. According to the club, Florian Kainz will end his professional career in the summer. Dominique Heintz will not receive a new contract.

These decisions mark the direction: Cologne is not just making changes at the edges, but is intervening in the core of the squad – whether through the departure of key players, letting contracts expire, or the willingness to part with players who are not planned as key pillars in sporting terms.

It remains open how large the second wave of upheaval will be. In Cologne, further departures are being discussed; according to EXPRESS.de, there is an internal list of players to be cut. What will be decisive is how consistently the club tailors the squad to Wagner's requirements – and what solutions the market offers.

The difficult cases: performance, perspective, market

Denis Huseinbasic

(24, contract until 2027) made 16 appearances and 750 minutes in league and cup. Under Wagner, he played 67 minutes in the first game against Frankfurt, then was not in the squad or remained on the bench three times. This is not a judgment on his fundamental quality, but a clear indication that his role is being re-evaluated – and that a player with a contract can quickly find himself in a competitive situation during pre-season, which is risky both in sporting terms and for market value.

Linton Maina

(26, contract until 2027) made 26 appearances, 1,099 minutes, as well as two goals and one assist. Wagner used him in all seven games, which initially sounds like trust. At the same time, the hoped-for output was missing, which would make a winger indispensable in an ambitious plan. For Cologne, the question will be whether Maina creates more value in a clearer system – or whether the club must be ready to act if a suitable offer comes in.

Luca Waldschmidt

(30, contract until 2027) has 26 appearances, 752 minutes, five goals and four assists. His record is better than his recent standing suggested: In the last game of the season in Munich, he was on the bench under Wagner. This may have been for tactical reasons, but it fits the picture of an open future assessment. For Cologne, Waldschmidt is about weighing up: creativity and finishing quality are rare – but only a real advantage if they can be consistently delivered within a functioning pressing and transition concept.

Jan Thielmann

(23, contract until 2028) represents a different category: identification and commitment are hardly questioned, but his development seemed stalled last season. In 27 games he scored three goals and provided one assist. Under Wagner, his playing time recently decreased: 75 minutes against Frankfurt, ten against Bayern, only the bench against Heidenheim. In a squad undergoing upheaval, exactly such a profile can become a touchstone: Does Thielmann remain a building block of a new framework – or does he become a candidate if Cologne wants to buy pace, penetration, and variability elsewhere?

Two personnel matters with special explosive power: van den Berg and Schwäbe

Rav van den Berg

(21, contract until 2030) was signed from FC Middlesbrough for eight million euros and, after a serious shoulder injury, made 14 Bundesliga appearances with 1,132 minutes. Under Wagner, he played 90 minutes against Frankfurt, then did not feature again. According to EXPRESS.de, in addition to sporting considerations, there were also deficits in attitude and disciplinary issues in training. In addition, there is a financial point that often accompanies transfers of this magnitude: according to available information, another appearance would have triggered a bonus payment of two million euros to Middlesbrough. Whether this mechanism was actually decisive has not been publicly confirmed – but it shows how closely sporting management and contract clauses are intertwined in modern squad building, especially when a player is tied down long-term.

Marvin Schwäbe

Is again a case that has an impact beyond the pitch. The goalkeeper played all 34 Bundesliga games in full, is captain and one of the most consistent performers. His contract runs until 2027; the early extension was already made public in 2023. According to EXPRESS.de, his agent Jörg Neblung is said to have offered the goalkeeper to two Bundesliga clubs. At the same time, Schwäbe has not ruled out talks about an early extension, while Cologne internally has so far seen no rush. A departure would be a sporting cut – and would change the entire hierarchy in the team. That is precisely why this personnel matter is a benchmark: How willing to compromise is the club if a key player is considering leaving? And how consistent is Wagner if the squad idea also concerns the goalkeeper position?

What Cologne must decide this summer

1. FC Köln is facing a transfer period in which not only gaps need to be filled. The club must determine which players fit Wagner's profile, for whom a sale would make sense – and where, despite a contract, no clear perspective is seen anymore. Some solutions will not depend solely on sporting will, but on whether suitable options can be found for the affected professionals.

The course is clear: Wagner is not only to coach, but also to help shape the squad. The open question is no longer whether the upheaval is coming – but how deep it will actually be.
