Bundesliga tactical preview: Bayer Leverkusen’s rebuild under Martinez

In the sleek training ground of Bayer 04 Leverkusen, the club’s new Catalan coach Carles Martinez Novell watches his squad drill, marking the start of the Bundesliga 2026/27 tactical preview that pits the red‑company side against a season of extensive change and a €11.35 million summer transfer surplus.

Umbruch ambitions

Last year Bayer Leverkusen formed half of the Bundesliga “XXL Umbruch” clubs that sought to reverse fortunes with a new coach and an almost completely revamped roster. The club’s ambition is to rebuild under the guidance of Carles Martinez Novell while still navigating a transition that is far from complete. Our Get German Football News series follows this evolution, highlighting the scale of change within the German side.

From a performance‑based perspective RB Leipzig certainly achieved more than Leverkusen last season. Both clubs dismissed their head coaches at the end of the campaign, underscoring the volatility that rivals even an American fast‑food chain’s staff turnover. Nevertheless, neither side can yet claim stability.

Leverkusen’s recent coaches have ranged from Spaniard Erik ten Hag to Dutchman Kasper Hjulmand, before the Catalan Martinez took over within twelve months. Ten Hag’s outspoken criticism of club management placed him in the “too cold” category, while Hjulmand’s subdued demeanor was deemed “too hot” by some observers. Martinez arrives with a flamboyant gesturing style, aiming to revive the “Xabi Alonso spirit” without being labeled the next Alonso.

Martinez steps in without grand expectations of an immediate turnaround, as the roster remains largely built for the future. The summer has already seen numerous arrivals and departures, confirming that the transition phase continues. Goalkeeper Alejandro Grimaldo cannot be replaced on a like‑for‑like basis, leaving the defensive line in flux.

Financial firepower

Leverkusen’s financial resources guarantee they will outspend most Bundesliga rivals by the close of the summer window. The club’s estimated summer transfer balance stands at +€11.35 million, and Simon Rolfes together with Fernando Carro are expected to maintain this spending edge into January. Facundo Medina and Miguel Gutierrez already provide Martinez with experienced options in midfield and attack.

These Bundesliga tactical Previews aim to dissect how the new coach will shape the team’s identity. One German footballing journalist, who asked to remain anonymous, described Martinez’s appointment as “an unsensational, yet exciting, choice.” The author cautions that the revolving door of personnel makes projecting line‑ups a challenging task.

While Bayer Leverkusen enjoys a devoted traditional fan base, many Germans view the club as an über‑rich company side whose wealth sets a neighborhood standard. The upcoming season will test whether the club’s financial firepower and coaching gamble can translate into on‑field stability.
