In the high-stakes environment of a Champions League last-16 second-leg decider, Mikel Arteta has signalled a tactical reset that could redefine Arsenal’s approach against Bayer Leverkusen at the Emirates Stadium tonight (Tuesday 17 March 2026, 8pm BST). While no official starting XI has yet been confirmed, the latest team news and predicted lineup represent a significant shift from recent patterns — one that Leverkusen will not have anticipated.
The headline changes centre on personnel rotation and careful squad management. Viktor Gyökeres is strongly fancied to lead the line, having been an unused substitute in the recent Premier League win over Everton. With Kai Havertz’s fitness being managed ahead of the upcoming Carabao Cup final, Arteta appears prepared to rest his regular striker and hand the Swedish international a platform to exploit his physicality and finishing threat in a must-win European tie.
Equally eye-catching is the expected return of Leandro Trossard. The Belgian winger missed Arsenal’s last two matches with a minor injury but participated fully in Monday’s training session and is tipped to reclaim his place in the starting XI. His creativity and versatility on the left flank add another layer of unpredictability that Leverkusen’s defensive structure may struggle to contain.
In midfield and defence, further subtle but impactful decisions are emerging. With captain Martin Ødegaard still unavailable, Eberechi Eze is poised to retain the No 10 role that he has occupied impressively in recent weeks. Declan Rice and new signing Martín Zubimendi are expected to form a solid double pivot in a 4-2-3-1 shape, providing the defensive stability required against Leverkusen’s fluid attacking transitions while allowing Bukayo Saka and Trossard licence to push forward.
At the back, Jurrien Timber is ruled out, forcing a choice on the right flank. Cristhian Mosquera — who impressed off the bench against Everton — is in contention to start ahead of Ben White. Should Mosquera be selected, Riccardo Calafiori would likely shift to a more attacking left-back brief on the opposite side, injecting additional width and overlapping runs that could stretch Leverkusen’s back line.
Mikel Merino remains sidelined following foot surgery, while young academy prospect Max Dowman is likely to be named among the substitutes after his eye-catching cameo in the Everton fixture. His presence on the bench offers Arteta a dynamic late-game option should the tie require a moment of inspiration.
Tactically, this predicted XI (Raya; Mosquera, Saliba, Gabriel, Calafiori; Zubimendi, Rice; Saka, Eze, Trossard; Gyökeres) strikes a balance between freshness and control. By prioritising Gyökeres’ mobility over Havertz’s hold-up play and restoring Trossard’s directness, Arsenal are signalling an intent to play with greater verticality and speed on the counter. The potential Mosquera-Calafiori full-back pairing further suggests an aggressive posture on the flanks — a setup that could catch Leverkusen cold if they prepare for the more familiar, conservative Arsenal shape seen in recent weeks.
The timing of these moves could not be more critical. Arsenal enter the second leg needing to overturn or protect a delicate aggregate scoreline, and Arteta has clearly chosen evolution over repetition. Whether the changes translate into the decisive performance required remains to be seen, but one thing is certain: the German champions will have spent the final hours before kick-off frantically reassessing their defensive organisation.
Tonight’s lineup, when officially confirmed, promises to be one of the most talked-about selections of the season — a genuine bombshell that underscores Arsenal’s depth, tactical flexibility, and willingness to gamble at the highest level. Leverkusen, beware.
