Mikel Merino's first-half header proved decisive as Arsenal secured a hard-fought 1-0 victory over Chelsea, closing the gap to Premier League leaders Liverpool to 12 points.
Both teams were missing key attacking players, with Arsenal's Kai Havertz sidelined for the season and Chelsea without Nicolas Jackson and star playmaker Cole Palmer.
The Blues struggled to create clear-cut chances in Palmer's absence, while Arsenal controlled much of the game.
Merino struck in the 20th minute, glancing Martin Ødegaard’s curling corner past Robert Sánchez.
Chelsea's best opportunity came when Marc Cucurella's powerful shot slipped through David Raya’s hands but rolled just wide.
Sánchez, recently restored as Chelsea’s first-choice keeper, endured a shaky night under Arsenal’s aerial pressure but produced a crucial save to deny Merino a second goal.
Despite late Chelsea pressure, Arsenal’s well-organized defense held firm.
Arsenal's Set-Piece Strength Keeps Them Alive
Mikel Arteta’s side has been more structured in recent seasons, but their attacking struggles have seen them fall behind in the title race.
However, set-pieces continue to be a crucial weapon, with Merino’s goal marking Arsenal’s 11th from corners this season.
Youngster Myles Lewis-Skelly impressed on his return to the starting XI, while fans were given a boost as Bukayo Saka was spotted pitchside, with hopes he could return in time for their Champions League quarter-final clash with Real Madrid.
Chelsea Lacking Firepower Without Palmer
Chelsea’s ambitions of securing a Champions League spot took a hit with this defeat.
Palmer’s absence was glaring, as he has contributed to 38% of Chelsea’s league goals this season.
Without him, Enzo Maresca’s side lacked creativity and cutting edge in the final third.
Pedro Neto, deployed as a makeshift striker, was well contained by Arsenal’s disciplined backline.
Chelsea are now winless in their last seven away league games, losing four in a row on the road, and will need to find attacking solutions if they are to stay in the hunt for a top-four finish.
