Key events
Those teams: Mikel Arteta makes one change to the side that beat Aston Villa last weekend, with Leandro Trossard coming in for Gabriel Martinelli on the back of his match-changing turn off the bench at Villa Park.
Fabian Hurzeler makes two changes, one of them enforced. In the absence of Billy Gilmour, who completed his move to Napoli yesterday, Carlos Baleba comes into Brighton’s midfield. Bart Verbruggen starts in goal, with Jason Steele dropping to the bench.

Early Brighton team news
Brighton midfielder Matt O’Riley is out for the foreseeable future following the atrocious tackle visited upon him by Crawley Town’s Jay Williams nine minutes into his debut on Tuesday night. Fabian Hurzeler has since revealed that the Denmark international will need ankle surgery.
Solly March is also sidelined with a knee injury, while Matts Wieffer is expected to be in the squad after missing the past two games with a minor injury.
Signed from Fenerbahce for the thick end of £26m during the week, Turkish utility man Ferdi Kadioglu has already suffered a muscle injury in training.
Bart Verbruggen returned from injury to make his first appearance of the season against Crawley Town and could start today in place of Jason Steele in goal. Scottish midfielder Billy Gilmour left the club for Napoli yesterday.
Early Arsenal team news
In one of the bigger Deadline Day stories, Arsenal signed Raheem Sterling on a season loan from Chelsea but while the winger will not be in today’s squad because he wasn’t registered in time, he is at the Emirates to watch his new teammates in action.
It’s been and up-and-down week for Mikel Merino, who arrived at the club on Wednesday from Real Sociedad, then suffered a shoulder injury in his very first training session with his new teammates. The unlucky midfielder hurt himself in a collision with Gabriel and Mikel Arteta expects him to be out for “a few weeks”.
Gabriel Jesus remains sidelined with the groin injury that ruled him out of the trip to Villa Park last weekend, although his condition is not believed to be serious. We can expect to see him back in action after the international break.
Kieran Tierney is still recovering from the hamstring injury that forced him off during Scotland’s group game against Switzerland at the Euros, while his fellow full-back Takehiro Tomiyasu continues his recovery from the knee injury that caused him to miss pre-season.
Arsenal’s reserve goalkeeper for all of last season and the opening two games of this one, the England international Aaron Ramsdale is hoping to reboot his career after joining Southampton on a permanent deal.
Premier League: Arsenal v Brighton
With four wins out of four matches between them so far this season in the Premier League, something has to give when Arsenal host Brighton at the Emirates Stadium.
Brighton kicked off their campaign with wins over Everton and Manchester United, while their hosts have notched up victories over Wolves and Aston Villa that weren’t quite as straightforward as the 2-0 scorelines suggest.
The perfect start to the season of at least one of these two sides will come to an end during a game in which two of the Premier League’s youngest, most innovative and animated managers will gesticulate excitedly from adjacent technical areas.
Kick-off at the Emirate is at 12.30pm but stay tuned in the meantime for team news and build-up.
