Honestly, trying to guess a London derby starting XI feels a bit like predicting the British weather in January. You think you’ve got it figured out because the sun is peeking through, and then suddenly, a tactical thunderstorm hits and your "guaranteed" starter is sitting on the bench in a puffer jacket. When it comes to Arsenal F.C. vs Chelsea F.C. lineups, the narrative usually revolves around who’s injured, but in 2026, it’s actually about who can survive the most grueling schedule we’ve seen in years.
We just saw these two go at it in the Carabao Cup semi-final first leg at Stamford Bridge. That 3-2 Arsenal win was a chaotic mess of high-pressing and defensive blunders that basically proved one thing: the name on the back of the shirt matters way less than how much gas is left in the player's tank.
The Rosenior Era and the Chelsea Selection Headache
Liam Rosenior is still basically finding the light switches at Cobham after taking over from Enzo Maresca. If you’re looking at the Chelsea side of the Arsenal F.C. vs Chelsea F.C. lineups, you have to realize he’s inherited a squad that is both ridiculously deep and strangely fragile.
Take the Robert Sanchez situation. He had a bit of a nightmare in that midweek cup clash, gifting goals like it was Christmas in mid-January. A lot of fans are screaming for Filip Jorgensen to get the nod. But here’s the kicker—Rosenior seems to value Sanchez's ability to ping balls into the channels more than he cares about the occasional "howler."
Then there’s the Reece James dilemma. It’s the same old story, isn’t it? He’s arguably the best right-back in the world when his hamstrings aren't made of wet tissue paper. He’s back in training, but starting him against a high-octane Arsenal side is a massive gamble. Most experts expect Josh Acheampong to keep his spot for now, simply because you can’t risk your captain snapping in a game this intense.

Chelsea’s Likely Tactical Shape
- Robert Sanchez: Despite the errors, he's still the guy Rosenior trusts for the build-up.
- The Back Four: Acheampong, Wesley Fofana, Trevoh Chalobah, and Marc Cucurella. It’s a bit of a "makeshift" feel, especially with Levi Colwill out with that ACL injury.
- Midfield Pivot: Moises Caicedo is back from suspension. That’s huge. He’ll likely partner Enzo Fernandez, though Andrey Santos has been knocking on the door.
- The Creative Hub: Cole Palmer. Obviously. If he’s 70% fit, he plays. He’ll probably be flanked by Pedro Neto and Alejandro Garnacho, who looked like a man possessed after coming off the bench in the cup.
- Leading the Line: Joao Pedro or Marc Guiu? It’s a toss-up, but Joao Pedro’s experience in big games usually gives him the edge.
Arteta’s "Untouchable" Arsenal Machine
On the flip side, Mikel Arteta has turned Arsenal into a relentless, soul-crushing machine. They aren't just winning; they're suffocating teams. When people talk about Arsenal F.C. vs Chelsea F.C. lineups, they usually assume it’s the same XI every week. And while Arteta loves consistency, he’s been forced to evolve.
The arrival of Viktor Gyokeres has changed everything. For years, Arsenal lacked that "monster" up front—someone who would just bully center-backs. Now they have it. His performance in the midweek 3-2 win was a masterclass in hold-up play.
But it’s the midfield that really makes you stop and stare. Martin Odegaard, Declan Rice, and Martin Zubimendi. On paper, that is arguably the most balanced midfield in world football. Zubimendi allows Rice to go on those marauding runs we saw at West Ham, while Odegaard just floats around in the "half-spaces" picking people apart.
The Arsenal Blueprint
- The Keeper: David Raya. Kepa played the cup games, but for the big league nights, Raya is the undisputed No. 1.
- Defensive Solidity: Ben White, William Saliba, Gabriel Magalhaes, and Jurrien Timber. It’s a brick wall. Saliba and Gabriel have a telepathic connection that makes you wonder if they share a brain.
- The Engine Room: Rice and Zubimendi. They provide the platform for the front four to cause absolute carnage.
- The Attack: Bukayo Saka is the first name on the sheet. On the left, it’s usually a coin flip between Gabriel Martinelli and Leandro Trossard. Given Trossard's knack for scoring in derbies, he’s the smart bet.
- The Finisher: Gyokeres. He’s the focal point everything revolves around now.
Why the "Injury Crisis" Narrative is Overblown
You’ll see headlines everywhere talking about how "depleted" these squads are. Don't buy it. Yes, Chelsea are missing Colwill and Lavia. Yes, Arsenal are without Calafiori and Hincapie. But look at the benches!

Arsenal can bring on Eberechi Eze, Gabriel Jesus, and Mikel Merino. That’s about £150 million worth of talent just sitting there waiting for the 70th minute. Chelsea have players like Estevao and Facundo Buonanotte who can change a game in a heartbeat. The "crisis" isn't a lack of players; it's the fatigue of the ones who are playing.
The real tactical battle in the Arsenal F.C. vs Chelsea F.C. lineups isn't about the 11 who start—it’s about the five who finish. Arteta has become a master of the "triple sub" at the hour mark to kill off games. Rosenior, being new to the job, is still learning how to pull those levers.
Key Matchups to Watch
You’ve gotta look at Saka vs. Cucurella. It’s become a bit of a personal feud lately. Cucurella is one of the few left-backs who actually enjoys the "dark arts" needed to slow Saka down. He’ll nip at his heels, pull his shirt, and basically try to annoy him into a red card.
In the middle, watch the Caicedo vs. Odegaard battle. If Caicedo can stop Odegaard from turning, Chelsea have a chance. If Odegaard gets his head up and sees the run of Gyokeres, it’s game over. It’s that simple, really.

Actionable Insights for Fans and Analysts
If you're tracking these lineups for fantasy football or just pure tactical interest, here’s what you should actually be looking at:
- Monitor the Warm-ups: In 2026, "late fitness tests" are often just smokescreens. Watch for who is doing high-intensity sprints 30 minutes before kickoff. If Reece James is only jogging, he’s not starting.
- The "Inverted" Fullback Factor: Watch Jurrien Timber. He rarely stays on the touchline. He’ll drift into midfield to create a box, which often leaves Chelsea’s wingers confused about who they’re supposed to mark.
- Set-Piece Dominance: Arsenal have scored 23 goals from set-pieces this season. If you see Gabriel and Saliba venturing up for a corner, Chelsea’s zonal marking system—which has been shaky under Rosenior—will be under massive pressure.
- Bench Depth: Look at the "Impact Subs." If the game is tied at 60 minutes, the team that brings on the more experienced attacking threat (likely Arsenal with Eze or Jesus) usually nabs the winner.
The lineups are a chess match that starts long before the referee blows the whistle. While the names might change due to a late-night hamstring tweak, the tactical intensity of this rivalry remains one of the few constants in the Premier League. Keep an eye on the official team sheets exactly 75 minutes before kickoff; that's when the real games begin.
Next Steps:
- Track the Injury Reports: Check the final training session photos on Friday afternoon; players not pictured are rarely in the starting XI.
- Analyze the Pivot: Focus on whether Rosenior sticks with the Andrey Santos/Enzo Fernandez pairing or brings Caicedo straight back in—it changes their entire defensive transition speed.
