Mikel Merino scored the only goal of the game as Arsenal beat Chelsea to move 12 points behind Premier League leaders Liverpool.
Both of these sides came into the match without their first-choice striker, with Kai Havertz ruled out for the season with a hamstring injury for Arsenal and Nicolas Jackson missing for Chelsea.
Chelsea were also without their most important player in Cole Palmer, who was out of the squad with an injury, and it was the first time the Blues have to had to play without him since they lost 5-0 to Arsenal in April last season.
Arsenal, again naming Merino as a makeshift striker, dominated the game early on and Leandro Trossard, Gabriel Martinelli and Declan Rice all went close.
Merino’s winner came in the 20th minute when he flicked on a curling corner from Martin Odegaard past a stretching Robert Sanchez.
Chelsea’s best opportunity to take something from the game came when Marc Cucurella’s powerful effort slipped through David Raya’s hands but the ball rolled just past the post.
Robert Sanchez, recently restored as Chelsea’s first-choice keeper, had some shaky moments as the Blues were put under pressure with a number of crosses into the area and he was jeered by the home crowd when he had the ball at his feet.
Sanchez produced an excellent save to deny Merino in the second half, but Chelsea could not find the goal to get something from the game.

Brentford Rebound To Beat Bournemouth
Brentford came from a goal down to beat Bournemouth at Vitality Stadium and register a fifth successive Premier League away win.
The hosts went in front when a Milos Kerkez cross went in off the shoulder of Brentford midfielder Vitaly Janelt.
However, Bournemouth’s lead lasted for only 13 minutes as Yoane Wissa headed in his 14th Premier League goal of the season from Bryan Mbeumo’s corner.
Brentford captain Christian Norgaard swept home the visitors’ winner when Bournemouth failed to clear a second-half long throw into their penalty area.
With Carabao Cup finalists Newcastle not in Premier League action and Manchester City drawing against Brighton earlier on Saturday, a Bournemouth win would have lifted them to sixth in the table.
However, their prospects of qualifying for Europe were dented as their winless Premier League run was extended to four matches.
Bournemouth stay ninth in the table, three points above 11th-placed Brentford, who remain on the fringes of the race for Europe.

Fulham Strengthen Bid For Europe
Fulham strengthened their bid for a European place by beating Tottenham at home for a second consecutive season, the first time they have achieved that in 19 years.
Rodrigo Muniz and Ryan Sessegnon scored in the closing 15 minutes to breathe life into what had been a largely drab Premier League London derby.
Fulham’s Timothy Castagne was the only player to send a shot on target in the first half and the next such attempt came via Tottenham’s Ben Davies in the 65th minute.
Spurs looked the most likely to break the deadlock as the second half progressed, with Dominic Solanke spurning three opportunities that included one at an open goal from five yards.
However, substitute Muniz, who scored twice when Fulham beat Tottenham 3-0 at Craven Cottage last season, put the hosts in front in the 75th minute with a cool side-footed finish.
Victory moves Fulham up to eighth in the standings and just four points adrift of fourth-placed Chelsea, while Tottenham remain 13th after another grim weekend for Ange Postecoglou.

City Stumble, Again
Manchester City stumbled again in the battle to secure a return to the Champions League as they were pegged back twice by fellow top-five challengers Brighton in an entertaining encounter at Etihad Stadium.
Erling Haaland became the first player to reach 100 Premier League goal involvements in fewer than 100 games when he marked his 94th appearance in the competition with his 84th goal by sending Brighton keeper Bart Verbruggen the wrong way with his 11th-minute penalty.
In a game of superb goals, Pervis Estupinan levelled with a curling free-kick that bounced in off a post, although City keeper Stefan Ortega, in for injured first-choice Ederson, did not cover himself in glory as he initially moved to his right before changing direction and eventually watching the ball go in with a shocked look on his face.
Forest Boost Top Four Chances
Nottingham Forest underlined their top-four credentials with a comfortable Premier League win over relegation-threatened Ipswich at Portman Road.
The result had moved Forest just a point behind second-placed Arsenal, who later beat Chelsea, and ever closer to Champions League football next term.
On an afternoon when Nuno Espirito Santo celebrated his 50th top-flight match in charge of Forest, his side ruthlessly exposed Ipswich’s defensive frailties in a devastating seven-minute period during the first half.
Nikola Milenkovic opened the scoring for the visitors with a rising shot from eight yards after home forward Liam Delap had inadvertently nodded the ball into the Serbia defender’s path.
And just over two minutes later Forest doubled their lead, as the Tractor Boys imploded.
However, George Hirst’s late goal at least allowed the home side to end the contest on a positive note.
Kieran McKenna’s Ipswich remain 18th – and are the only club in the top four divisions of English football without a league win in 2025.
