[14][15] Arsenal had four players unavailable for pre-season friendlies, as Bernd Leno, Bukayo Saka, Kieran Tierney, and Granit Xhaka had competed in Euro 2020, which ended on 11 July.
[23][24] Arsenal concluded the month with the announced signing of 23-year-old English centre-back Ben White on 30 July, who joined from fellow Premier League club Brighton & Hove Albion on a £50 million deal.
Granit Xhaka's second-half header equalised after Kai Havertz's first-half goal, but minutes later, Tammy Abraham capitalised on an Arsenal defensive error to give Chelsea the lead again.
[28][29] For their last pre-season game, Arsenal played their second Mind Series match, this time away to Tottenham Hotspur on 8 August, with Ben White joining fellow new signing Albert Sambi Lokonga in the starting lineup.
After both teams came close to scoring on several occasions, Tottenham broke the deadlock in the 79th minute, as Son Heung-min finishing off a cross from Serge Aurier for the game's solitary goal.
The Gunners began the season without Alexandre Lacazette and captain Pierre-Emerick Aubameyang, who were ruled out a few hours prior to kick-off due to illness, while Ben White and Albert Sambi Lokonga made their competitive debuts for the team.
With just over 10 minutes to go, Son Heung-min finally scored Tottenham's first goal of the match after receiving Sergio Reguilón's cross; Aaron Ramsdale managed to get his left hand to the ball but could not keep it out.
Arsenal finally drew even in the fifth minute of stoppage time, with a shot from Ben White deflected by Guaita into the path of substitute Alexandre Lacazette for a tap-in, and the game ended 2–2.
In first-half stoppage time, referee Craig Pawson consulted the pitchside VAR monitor for Matt Targett's challenge on Alexandre Lacazette and awarded Arsenal a penalty.
Tavares's through pass to Aubameyang was then flicked forward to Smith Rowe, who continued his run before eventually firing a shot that deflected off Tyrone Mings and the near post past Martínez.
Aston Villa were able to score a consolation goal late in the match when Leon Bailey's run along the edge of the box took the ball into the path of Jacob Ramsey, whose first-time shot found the top corner, but Arsenal hung on for the 3–1 victory.
Among these was a leaping save near the end of the first half to parry a James Maddison free kick onto the crossbar before Evans's shot from the rebound was cleared off the line by Thomas Partey.
[80][81] Arsenal's successful defensive performances led to Aaron Ramsdale being nominated for the Premier League's Player of the Month Award, which was ultimately won by Liverpool's Mohamed Salah.
In the 56th minute, Ben White regained possession of the ball in the Arsenal offensive third and ran forward, evading Juraj Kucka and Joshua King before running into Moussa Sissoko.
Shortly before halftime, after Emile Smith Rowe's header was saved by Martin Dúbravka, Pierre-Emerick Aubameyang missed from close range and kicked the rebound against the outside of the post.
[91] From a 13th minute corner by Martin Ødegaard, Emile Smith Rowe scored the opening goal from outside of the box, with the assist from Mohamed Elneny after Harry Maguire's initial clearance.
Shortly before halftime, Manchester United equalized after Jadon Sancho passed infield to Fred, who squared the ball for Bruno Fernandes to slot it in past Aaron Ramsdale.
However, Arsenal equalized less than two minutes later; on the right flank, Gabriel Martinelli received Thomas Partey's through pass before firing a low cross into the box for Ødegaard, whose shot curled in past the reach of de Gea.
On 87 minutes, after Takehiro Tomiyasu dispossessed Saïd Benrahma, Bukayo Saka recovered the ball before passing it near the center line to substitute Emile Smith Rowe, who continued his run and scored a second goal for Arsenal.
Cédric's corner in the 17th minute was headed towards goal by Rob Holding, only for Lee Burge to parry the ball into the path of Eddie Nketiah, who continued his three-match run of scoring in the EFL Cup and put in the tap-in from close range.
The 5–1 result advanced Arsenal to the semi-finals for the first time since the 2017–18 edition, while Nketiah's hat trick made him the joint top goalscorer with Brentford's Marcus Forss on five goals.
However, Arsenal took the lead after the half-hour mark when Kieran Tierney found Bukayo Saka in the box, who slotted the ball in as Alexandre Lacazette screened off Nathan Aké.

In the 24th minute, Granit Xhaka was sent off by referee Michael Oliver for a high boot and a denial of a clear goal-scoring opportunity, as the former attempted to intercept a long pass from Andrew Robertson to Diogo Jota.
However, Brentford scoring a consolation goal in stoppage time, with a scramble in the box following a Saman Ghoddos free kick resulting in Christian Norgaard's close-range strike, which was confirmed after a VAR check for offside.
Five minutes into stoppage time, Alexandre Lacazette received a pass from Pépé and shot towards goal, with the strike being diverted into the top corner off José Sá's glove, giving Arsenal another 2–1 win.
Rob Holding and Gabriel scored for Arsenal either side of a West Ham equaliser from Jarrod Bowen to secure a 2–1 victory for the Gunners, which extended their win streak to three.
Both of the match's goals would come in the second half, as a 56th-minute opener from Callum Wilson followed by an 85th-minute strike by Bruno Guimarães gave Newcastle a 2–0 victory and saw Arsenal fall below Tottenham in the table on the penultimate matchday.
