Defensive Solidity, Attacking Struggles: Sarri Evaluates System Change Post-Fenerbahce

Maurizio Sarri’s Lazio suffered their first preseason defeat in Turkey, falling 1-0 to Fenerbahce at the Şükrü Saracoğlu Stadium. It was a test of greater intensity than the Primavera or Avellino matches—and while the scoreline favored José Mourinho's side, it was a match filled with key takeaways, especially for Sarri’s defensive project and potential tactical evolution.

The decisive goal came from a moment of inattention: a misguided back pass by Guendouzi, punished clinically by Fenerbahce. Beyond the result, though, Sarri appeared focused on growth and structure rather than scoreboard outcomes. This early loss will sting, but it offers a crucial learning opportunity.

If there’s one clear positive, it’s the defensive structure taking root. Sarri’s best Lazio—the one that clinched second place in Serie A with 21 clean sheets—was defined by balance and discipline at the back. Despite a transfer ban leaving the squad largely unchanged, the backline continues to grow in cohesion.

Nuno Tavares, a physical and technically gifted presence, stood out. Sarri previously admitted the Portuguese was “more tactically prepared than expected,” and against Fenerbahce, he again showed why. Together with Provstgaard and returning figures like Romagnoli and Gila, Lazio’s defense is starting to reflect the geometrical precision that Sarri’s systems demand.

But goals have been scarce in preseason, and the reasons are layered. Heavy training loads, disjointed movement, and lack of rhythm have all played a part. As last season showed, a solid defense is vital—but if Lazio are to return to Europe, the attack must eventually click. For now, Sarri is willing to be patient, provided the foundation is solid.

With another test looming against Galatasaray on August 2nd, Lazio’s preseason tour in Turkey ramps up. It will be another opportunity to refine the system, test rotations, and evaluate whether the tactical revolution Sarri envisions is truly the future of this squad.

This preseason may also mark the birth of a more flexible Lazio. For the first time, Sarri is seriously contemplating breaking away from his trademark 4-3-3. With limited reinforcements, the coach is considering a shift to a 4-3-1-2, a move that could unlock new synergies.

Zaccagni, typically a winger, could be repurposed into a true No. 10 role behind Castellanos and Dia. It’s an idea born from necessity, with Isaksen sidelined due to illness and Dele-Bashiru still adapting to the tactical rigor of Sarri’s methods. Though physically promising, the Nigerian has yet to demonstrate the consistency needed in the mezzala position.

The midfield remains the most uncertain department. Belahyane has been trialed in multiple roles, Rovella continues to serve as a reliable deep-lying playmaker, and Vecino provides physicality and grit. But the collective output has been inconsistent, and Sarri is visibly concerned about the lack of creative spark in the middle.

A tactical reshuffle may be the only path forward. With the team’s dynamic profile and limited individual flair, simplifying roles and reducing reliance on wide play may help Lazio stay compact without sacrificing offensive balance.
