  Arsenal turn up at the Stadium of Light with a perfect start to defend - three wins from three, top of the table, and the sort of form that makes everyone else nervous this early in the season. For Sunderland, sat in mid-table respectability on four points, this isn't really about the league table at all; it's about landing a genuine shock against the best team in the country right now and giving their own fans a story for the ages. Arsenal losing here wouldn't be catastrophic in September, but it would hand the rest of the division a reason to believe the leaders are human after all.

  These two have needed no time at all to build a bit of needle. Last season's meeting at the Stadium of Light finished 2-2 after Sunderland snatched a stoppage-time equaliser through Brian Brobbey, ruining what looked like a routine away day for Arsenal. Arsenal got their revenge in February, winning 3-0 at the Emirates with Viktor Gyokeres helping himself to a second-half brace, so Sunderland will fancy a repeat of the first instalment rather than the second.

  Keep an eye on Granit Xhaka, who spent years as Arsenal's captain before leaving for Bayer Leverkusen and now finds himself lining up against his old side and his old boss, Mikel Arteta. He's been Sunderland's most important player in midfield this season - leading the squad for touches, chances created, and successful passes - proof that leaving Arsenal in 2023 didn't exactly finish him off. If Sunderland are going to have control anywhere in this game, it will start with him pulling strings against the club he used to captain.

  Arsenal go into this without William Saliba, still out long-term, which is a genuine concern given how much of their defensive solidity has been built around him - though you wouldn't know it from a defence that's conceded the fewest expected goals in the league this season. Sunderland have their own absentee in Habib Diarra, sidelined with a hamstring injury and not expected back until after the international break. Both sides are managing without a key piece, but only one of them has looked untroubled doing it.

  Arsenal have won five straight in all competitions, scoring ten and conceding just one - numbers that read more like a video game difficulty setting than a real Premier League season. If any team fancies putting a dent in that run, it's a Sunderland side that has already spoiled an Arsenal afternoon once in this fixture's short history, with that stoppage-time draw last season still fresh in the memory at the Stadium of Light. Arsenal have gone away and won the rematch before, mind, so nobody at the Emirates will be losing sleep just yet.

  Sunderland are into their second season back in the Premier League and have started like a team that's decided top-flight football isn't going to scare them — a 1-0 win over Fulham and a battling 1-1 draw at Brentford where they arguably had the better chances and rattled the post.

  Striker Wilson Isidor scored the winner against Fulham just days after signing a new contract with the club — good timing, and exactly the kind of moment that makes a new deal look smart within a week.

  Last season Sunderland provided one of the division's most dramatic subplots without really meaning to: a 1-0 win over Tottenham in April ended with Spurs captain Cristian Romero in tears and out for the rest of the season with knee ligament damage.

  It's the sort of result that gets brought up by other clubs' fans more than Sunderland's own — a reminder that a newly promoted side can do real damage to a club with much bigger ambitions.

  Two seasons ago that Romero afternoon would've been the story of Sunderland's season; now it barely comes up in their own build-up, which says a lot about how quickly they've settled into staying up rather than just scraping by.

  Arsenal finally got over the line last season, winning their first Premier League title in 22 years after three straight runner-up finishes. Mikel Arteta's side pipped Manchester City to it on the final day, so mention that specifically — Gunners fans have earned the bragging rights and they know it.

  The title defence opened with Arteta insisting there's no extra pressure: "we start from scratch," he said, since the trophy doesn't carry any advantage into a new season. It's the kind of line managers always trot out, but with this Arsenal side it actually sounds like they mean it.

  William Saliba, one of the best centre-backs in the league, is out with a back injury picked up at the World Cup with France and isn't expected back until around November. Drop that one in and you'll sound like you actually follow Arsenal's team news, not just their results.

  Arsenal spent big over the summer on Bruno Guimarães from Newcastle to add steel in midfield — exactly the kind of signing that says "we're not messing about this time." Arteta's already flagged his fitness as one to watch, so don't be surprised if he's managed carefully early on.

  Arsenal spent most of the summer chasing Julian Álvarez from Atlético Madrid, only for him to snub them for Barcelona on deadline day. Mention it lightly — it's not a disaster, just the kind of near-miss Arsenal fans have learned to shrug off by now.
