Arsenal goalkeeper Raya made two vital saves to keep out Jørgen Strand Larsen's close-range header and Pablo Sarabia's first-time volley.

The hosts thought they had taken the lead on 54 minutes when Amadou Onana's deflected shot looped up onto the crossbar, with the rebound falling for an unmarked Ollie Watkins to head home from close range, only for Arsenal goalkeeper Raya to get off the ground to make a stunning one-handed stop,[58][57][59] which would later win August 2024's Premier League Save of the Month award.

[57] On 30 August, Arsenal announced that new recruit Mikel Merino, who joined the club just three days prior, suffered a shoulder injury in his first training session with the team.

[63][64] Twelve Arsenal first-team players (excluding players who were loaned out) were named in their respective countries' senior squads for international fixtures in September: Gabriel Magalhães (Brazil), Rice and Saka (England), Saliba (France), Partey (as Ghana's captain),[67][68] Havertz (Germany), Calafiori (Italy), Jurriën Timber (Netherlands), Martin Ødegaard (as Norway's captain), Kiwior (Poland), Raya (Spain), and Zinchenko (Ukraine).

Twenty-two first-team players and young goalkeeper Tommy Setford who joined Arsenal's academy from Dutch side Ajax in July 2024,[70] were registered on the Squad List A.

[83][84] 10-man Arsenal battled hard in the second half until the eighth minute of stoppage time when John Stones latched onto a rebound and netted an equaliser for the hosts.

[88] Defender Maldini Kacurri made his senior debut as a substitute in the 70th minute, becoming the first Albanian national to represent Arsenal's first team in the club's history.

[93] Fifteen minutes later, Saka curled a low free-kick from wide on the right into a crowded penalty area; the ball somehow evaded everyone and flew straight into the back of the net.

[94] Ahead of the second international break of the campaign, Arteta's men played their seventh match in 21 days on 5 October when they faced newly promoted Southampton at home.

[98] Already missing Ødegaard and Saka through injury, the Gunners lost Saliba in the 30th minute as the French centre-back was shown the first red card of his career for a foul on Evanilson near the halfway line after a poor backwards pass from Trossard.

[113] The Gunners had a penalty shout in the 28th minute when Merino appeared to beat Inter goalkeeper Yann Sommer to a high ball in the box and took a punch to the head in the process, but VAR decided not to overturn a no-penalty decision.

After a scoreless first half that saw Havertz had a goal ruled out for offside by VAR,[116] Martinelli put Arsenal in front on the hour mark when he tucked home a cross by Ødegaard, who made his first start since 31 August.

[117] Arsenal squandered a golden chance in stoppage time, as Saliba played an inviting ball across the Chelsea box, but Trossard poked wide from close range, with Havertz waiting to tap home behind him.

[116] A run of early-season injuries for Arteta's side continued, as it was reported on 13 November that White had undergone a surgery to resolve a knee issue that he had been carrying for weeks, and would be sidelined for about two months.

[129] Although Gonçalo Inácio pulled one back for Sporting shortly after the break,[125] Saka's penalty and Trossard's header from a rebound secured Arsenal's victory.

[145] The Gunners turned the game around in the second half when Gabriel Jesus scored a hat-trick, ending his 367-day Emirates goal drought dating back to 17 December 2023.

They wore black armbands in remembrance of George Eastham,[147] who served as Arsenal captain between 1963 and 1966 and was a member of England's 1966 World Cup-winning squad,[148] following the earlier news of his passing.

[150] The victory marked the final away match of 2024 for Arsenal, making them the first team in English top-flight history to score five or more goals in six different away games in all competitions across a full calendar year.

[156] Bryan Mbeumo gave the hosts an early lead, but a Gabriel Jesus first-half header and second-half strikes from Merino and Martinelli turned the game around.

[159] However, referee Anthony Taylor awarded the hosts a controversial penalty after a few seconds of reflection, adjudging Saliba to have fouled Pedro, and VAR confirmed the decision.

Son Heung-Min's deflected effort gave the visitors the lead,[168] but a Dominic Solanke own goal and a Trossard strike turned the game around before half-time.

[173] Arteta's side took the lead in the second minute when Havertz cushioned a cross into the path of Rice, who volleyed home his first Champions League goal and Arsenal's earliest in the competition since 2014.

[179] Seven minutes later, Wolves midfielder João Gomes received a second yellow for a studs-up challenge on Timber,[180] which left both sides a man down for the remainder of the match.

[178] It was reported on 28 January that Lewis-Skelly would not serve a three-match suspension after Arsenal's appeal against his red card at Wolves was upheld by an FA's independent regulatory commission.
