Arsenal's watertight defence faces Chelsea's lethal attack in Super Sunday showdown

The numbers paint a stark picture. Arsenal have allowed fewer than 0.5 expected goals in 20 of their past 40 league games — a span covering last season and this campaign's opening two fixtures. No other club comes close; Liverpool sits second with eight such games. That defensive foundation has held firm even with William Saliba absent and Jurrien Timber sidelined.

Mikel Arteta's tactical blueprint has proven robust enough to absorb those absences. Cristhian Mosquera has slotted alongside Gabriel at centre-back, Ben White has stepped into right-back, and Riccardo Calafiori completes a back four that had never started a Premier League match together before the season opened. The system, not individual brilliance, is doing the heavy lifting.

Chelsea arrive having scored seven goals in two games, spearheaded by Morgan Rogers — the winger Arsenal pursued before his move to Stamford Bridge. In Chelsea's 4-3 win over Brighton, Rogers operated from the left, creating chances with pace and precision. According to Sky Sports, he represents exactly the kind of creative threat Arsenal have struggled to address in their own attack this summer, following failed moves for Vinicius Junior and Julian Alvarez.

That imbalance — Arsenal's defensive supremacy versus their attacking limitations — will define Sunday's contest.
