Arsenal's defensive solidity in Europe is putting them on the brink of history. The Gunners are now within striking distance of the Champions League record for most clean sheets in a single campaign, a benchmark currently held by their London rivals, Chelsea.

The charge is being led by goalkeeper David Raya, who recorded his seventh shut-out of the tournament in a hard-fought 1-0 away win against Sporting CP in the quarter-final first leg. His performance was so impressive that manager Mikel Arteta labelled him "extraordinary" after the final whistle.

To break the record, Arsenal must surpass the nine clean sheets Chelsea achieved during their triumphant 2020-21 season. That campaign was defined by the heroics of Edouard Mendy, who conceded just four goals throughout and kept a clean sheet in the final against Manchester City, earning him top individual goalkeeping honors.

Arsenal has a structural advantage in this pursuit. The newly expanded Champions League format means teams play eight group-stage matches instead of six, giving Mikel Arteta's side two extra games to chase the record, provided they continue their deep run. With the defense operating at an elite level, a historic defensive achievement is now a tangible target for the North London club.
