Riccardo Calafiori's Impact in Arsenal's London Derby Against Chelsea

Riccardo Calafiori’s surge through Arsenal’s season continues, and now it runs straight into a London derby.

Mikel Arteta has handed the Italy international another start for Sunday’s clash with Chelsea, rewarding a blistering opening to the campaign that already has him on the Premier League’s August Player of the Month shortlist. Two games, two assists, and a constant threat from deep have pushed the defender straight into the heart of Arsenal’s title defence.

This time, he lines up on the left of the back four, but that’s only the starting position on the teamsheet. Once the whistle goes, Calafiori’s role stretches far beyond a traditional full-back. He steps high, joins the midfield, and often looks like an extra playmaker rather than a defender, giving Arsenal an extra layer of control and incision down that flank.

The chemistry is already there. At Emirates Stadium on August 21, he combined with Kai Havertz as the German forward struck Arsenal’s first goal in their Premier League 2026/27 home outing, a moment that underlined how quickly Calafiori has settled into Arteta’s system.

Chelsea, meanwhile, travel across the capital without their own Italian option. Marco Palestra remains sidelined with a minor fitness issue, leaving the visitors short of that particular stylistic mirror on the opposite side.

Arsenal's Starting XI

Raya; White, Konsa, Gabriel, Calafiori; Rice, Lewis-Skelly, Odegaard; Saka, Tzolis, Havertz.

Calafiori’s name sits there on the left, but his influence is likely to stretch across the entire pitch. In a derby that often hinges on small details and one decisive surge, his form could tilt the afternoon.
