The Silent Architect: Why Julian Nagelsmann Remains Committed to Kai Havertz

In the high-stakes theater of international football, few positions are as scrutinized as the German No. 9. For decades, the role was defined by physical archetypes—the pure finishers who lived in the penalty area. Yet, as the DFB (Deutscher Fußball-Bund) continues its tactical evolution under head coach Julian Nagelsmann, the reliance on Kai Havertz has become one of the most debated, yet statistically grounded, features of the modern German squad.

While fans and pundits often clamor for the traditional presence of an out-and-out striker like Deniz Undav—a player whose movement and finishing are tailored for the classic center-forward role—Nagelsmann’s tactical blueprint suggests a different priority. The question is not simply who scores more goals, but who facilitates the systemic rhythm that allows Germany’s creative midfielders to flourish.

The Tactical Calculus: Why Havertz Isn’t Going Anywhere

To understand the persistence of the Havertz-as-striker experiment, one must look at the geometry of the pitch. Nagelsmann’s system relies heavily on fluid rotations. Havertz, a product of Bayer Leverkusen’s academy and a veteran of the Premier League, operates as a “space investigator.” He does not merely wait for service; he creates gaps by dragging center-backs out of their defensive blocks.

When Havertz drops deep, he effectively functions as an auxiliary playmaker. This movement serves a dual purpose: it creates space for players like Florian Wirtz and Jamal Musiala to operate in the “half-spaces,” and it forces opposing defenders into uncomfortable decisions regarding their defensive structure. While Deniz Undav offers a more clinical profile in terms of pure finishing, he lacks the specific hybrid experience that Havertz brings to a system designed for high-possession dominance.

Deniz Undav and the Traditionalist Appeal

The argument for Undav is rooted in the visceral desire for a “goal-getter.” Since his emergence, Undav has showcased a knack for being in the right place at the right time—a trait that remains the most valuable currency in soccer. His performance metrics in the Bundesliga consistently highlight his efficiency in front of goal, making him a compelling alternative when Germany needs to break down low-block defenses that are content to sit deep and absorb pressure.

However, international football is a game of compromise. Nagelsmann must balance the squad’s need for a focal point with the need for defensive stability during transitions. Havertz’s defensive work rate and his tactical intelligence in pressing situations provide a level of security that coaching staffs prioritize when preparing for tournament-level opponents.

The Data Behind the Decision

If we look at the official DFB team statistics, the focus on “link-up play” over “pure volume of shots” is evident. Havertz’s involvement in the build-up phase—measured by secondary assists and pre-assist passes—is significantly higher than that of more traditional strikers in the pool. For a team that dominates possession, the center-forward is often the first defender and the primary pivot point.

While the fan base may view the position through the lens of individual highlights, the coaching staff views it through the lens of team-wide expected goals (xG). When Havertz is on the pitch, the collective xG for the team’s attacking midfielders tends to rise. What we have is the “silent” value he brings: he makes the team better by making his teammates more effective.

Key Tactical Differences

• Kai Havertz: Facilitator, space-creator, high defensive output, hybrid playmaker.
• Deniz Undav: Clinical finisher, traditional movement, high efficiency in the box, specialist profile.

Looking Ahead: The Path to the Next Tournament

As Germany prepares for its upcoming international fixtures, the debate will inevitably continue. Nagelsmann has shown a willingness to adapt, but his loyalty to Havertz suggests he believes the current structure is the highest-ceiling version of this team. The challenge for Undav and other emerging strikers will be to prove that they can adapt their game to provide the same level of tactical utility, or for the team to evolve into a structure that can accommodate a more traditional presence without sacrificing the fluidity that defines Nagelsmann’s philosophy.

For now, the starting role remains with the man who best understands the manager’s vision. Fans can expect to see this tactical tug-of-war continue until the next major international window, where the DFB will look to solidify its roster ahead of the next qualification cycle.
