Arsenal's 2025/26 season reached a critical juncture as they hosted Sporting CP in the second leg of their Champions League quarterfinal. Carrying a narrow 1-0 aggregate lead from Portugal, courtesy of a late Kai Havertz strike, the pressure was immense. With their Premier League title charge also under threat, this was a moment for the Gunners to seize their destiny and advance in Europe.

Mikel Arteta opted for a pragmatic setup, deploying a back line of four natural center-backs, with Cristhian Mosquera starting at right-back over Ben White. Gabriel Martinelli returned on the left wing, while Leandro Trossard began on the bench. The squad was still missing the influential Bukayo Saka, and there were pre-match fitness concerns over Declan Rice, though he was passed fit to start. Key absentees included Martin Odegaard, Riccardo Calafiori, and the long-term injured Jurrien Timber and Mikel Merino.

The starting XI took the field in a 4-3-3 formation: Raya in goal; a defense of Mosquera, Saliba, Gabriel, and Hincapie; a midfield trio of Zubimendi, Rice, and Eze; and an attacking line of Madueke, Gyokeres, and Martinelli. The bench held further options, but the onus was on those starters to deliver a performance worthy of a Champions League semifinal berth.
