Liverpool Formation vs Arsenal 2026: A Tactical Case Study in Transition

By The Kop Review – Tactical Analysis Desk

The 2025/26 Premier League season presents a fascinating paradox for Liverpool Football Club. After a triumphant 2024/25 campaign under Arne Slot, the summer window brought a seismic shift in personnel. The arrivals of Alexander Isak, Florian Wirtz, Jeremie Frimpong, and Milos Kerkez signaled a clear intention: to evolve from the high-octane, gegenpressing identity of the Klopp era into a more possession-dominant, technically refined system. The early-season clash against Arsenal, a perennial title rival, served as the first true litmus test of this new philosophy. How did Slot approach this fixture? And what does the chosen formation reveal about Liverpool’s tactical trajectory?

The Pre-Match Puzzle: Identity vs. Opposition

Facing Mikel Arteta’s Arsenal is never a straightforward tactical exercise. The Gunners have mastered a hybrid 4-3-3/3-2-5 shape in possession, using their inverted full-backs to create a midfield overload. Slot’s challenge was twofold: first, to neutralize Arsenal’s central control, and second, to ensure his new-look side didn’t fall into the trap of becoming predictable.

The chosen starting XI—and its formation—was the most telling detail. Rather than deploying the 4-2-3-1 that had been the backbone of the 2024/25 title win, Slot opted for a fluid 4-3-3 that, in possession, morphed into a 3-2-5. This was not a defensive retreat, but a calculated structural adjustment.

The Tactical Blueprint: Three Key Adjustments

1. The Inverted Left-Back (Kerkez vs. Martinelli) The most critical tactical decision was the deployment of Milos Kerkez. Traditionally an overlapping full-back, Kerkez was instructed to invert into a central midfield role when Liverpool had the ball. This created a numerical 3v2 in the first phase of build-up against Arsenal’s initial press. By pulling Arsenal’s winger (likely Bukayo Saka or Gabriel Martinelli) inside, Kerkez opened a corridor for Frimpong to exploit on the right. The trade-off was clear: Liverpool sacrificed defensive width on the left for central control. In the first 30 minutes, this paid dividends, as Liverpool consistently bypassed Arsenal’s first line of pressure.

2. Wirtz as the "Free Eight" Florian Wirtz was not used as a traditional number 10. Instead, he operated as a "free eight," drifting between the left half-space and the center circle. This role is a direct evolution of the one previously occupied by Dominik Szoboszlai, but with a key difference: Wirtz’s first instinct is to receive on the half-turn and drive at the defense, rather than recycling possession. Against Arsenal’s compact 4-4-2 block, this was essential. It forced Declan Rice—Arsenal’s defensive midfielder—to make a choice: track Wirtz and leave space for Isak, or hold his position and allow Wirtz to shoot from distance.

3. The False 9 Role for Isak Alexander Isak’s arrival was viewed by many as a direct replacement for Darwin Nunez’s physicality. However, Slot utilized Isak as a false 9, dropping deep to link play and then spinning in behind. This was a deliberate ploy to drag Arsenal’s center-backs, William Saliba and Gabriel Magalhães, out of their comfort zone. In the first half, Isak’s movement created two clear chances: one for Salah, who hit the post, and another for Wirtz, saved by the Arsenal goalkeeper. The formation was less a rigid 4-3-3 and more a 4-3-3/4-2-4 hybrid, with Salah and Frimpong acting as wide targets.

The Second Half Adjustment: When Plans Meet Reality

Arsenal, predictably, adjusted at halftime. Arteta instructed his wingers to stay wide, forcing Liverpool’s full-backs to defend in isolation. The 3-2-5 shape, which had been so effective in build-up, became a liability. Kerkez, now isolated against Saka, was caught in transition twice, leading to Arsenal’s equalizer.

Slot’s response was to shift to a 4-2-3-1 with Gravenberch dropping into the back line to form a back three, while Frimpong was pushed higher. This was a pragmatic retreat—a recognition that the high-risk, high-reward 3-2-5 was unsustainable against a team of Arsenal’s quality for a full 90 minutes.

Conclusion: A Work in Progress

The fixture ended in a 1-1 draw—a result that felt like a missed opportunity for Liverpool, but a point gained in the context of the new system. The formation chosen by Slot was not a failure, but it was a clear signal of the club’s strategic direction. The 3-2-5 in possession is the future, but it requires a level of defensive synchronization that takes months—not weeks—to perfect.

Key Takeaways for the Season Ahead:

• The inverted full-back (Kerkez) is a non-negotiable part of Slot’s plan, but it leaves the team vulnerable to elite wingers.
• Wirtz’s fluidity is a weapon, but it requires the midfield to cover more ground defensively.
• Isak’s false 9 movement works best when the wide players (Salah, Frimpong) are direct and aggressive.

For Liverpool to challenge for the title in 2025/26, the formation must become more than a theoretical concept. It must become instinct. The Arsenal match was a valuable case study—a reminder that evolution in football is rarely linear, but always necessary.
