This Arsenal vs Chelsea tactical breakdown starts with the shock of it:
Morgan Rogers stealing in from the edge of the box to put Chelsea ahead inside the first 90 seconds, before most of the Emirates crowd had properly sat down.
Arsenal needed until the 25th minute to level it, Kai Havertz driving a finish beyond Emiliano Martinez, and it was the 50th minute before Martin Odegaard turned it around completely, finishing off a Havertz dummy and a Christos Tzolis pass.

Arsenal vs Chelsea Tactical Breakdown: A Patient First Half
It could hardly have started worse for the hosts. Rogers’s opener came from a cleared free-kick that Arsenal never properly dealt with.
And for the next quarter of an hour or so Chelsea defended that lead calmly enough that the setback barely showed. Arsenal didn’t panic either.
Ezri Konsa, handed his full debut, and Gabriel spread out either side of Raya when building from a goal-kick, as if daring Chelsea to come and get the ball off them, and more often than not Chelsea obliged, charging into a press that never quite arrived in time. That was the trick: Declan Rice would drop into the pocket the two centre-backs had just vacated, take a touch, and either turn up-field himself or fire the ball diagonally out to Ben White and Saka before Chelsea’s front line had reset. Simple, and repeated often enough that it stopped looking like luck.
There were other, quieter problems for Chelsea to solve. Riccardo Calafiori kept drifting inside off the left, close enough to Myles Lewis-Skelly that Cole Palmer never quite knew whether to follow him or hold his position, and when Pedro Neto tucked in to help, it left Christos Tzolis alone against Josh Acheampong out wide — a matchup Arsenal were happy to keep finding.
Arsenal also went long a few times, Raya picking out Kai Havertz early on, until Maxence Lacroix started shadowing him everywhere he went. It looked like a route shut down. It wasn’t — Havertz simply banked the attention for later, and cashed it in himself for Arsenal’s 25th-minute equaliser.
Chelsea tried to cope the only way sides at this level really can: squeezing their back five or back three across to whichever side Arsenal were hurting them, mostly the right.
But every time they shifted, Rice would drop in alongside Gabriel and Konsa to cover the risk of being caught out on the counter, with Lewis-Skelly sat in front of them blocking the most direct route through the middle — which meant even when Chelsea won it back, they were forced wide and given nowhere quick to go, and Arsenal had time to get back into their shape.
Further forward, Ben White in particular became the free man again and again, arriving late into moves that Saka and Odegaard had started, timing his runs to arrive just as the other two combined. Calafiori, meanwhile, made a nuisance of himself in the pocket between Reece James and Wesley Fofana, dragging Acheampong out of position to help, and Havertz — for a striker who didn’t get many clean touches near goal — was constantly peeling off the last defender to link play, taking a marker with him and opening the door for somebody else.
When Arsenal did break through, the pattern was almost always the same: a run to the by-line, a cutback, and a strike from the middle of the box — still the hardest kind of chance for any goalkeeper to keep out.
A Different Arsenal After the Break
Arsenal took the lead early in the second half, and did it through the move of the game: Havertz, still being shadowed everywhere by Lacroix, laid a dummy over a pass from Tzolis and let it run through for Odegaard to finish. Two Arsenal players had effectively combined to remove themselves from the equation and still create the goal — the clearest example all afternoon of a marking job being turned against the marker.
From there, Arsenal stopped letting Chelsea breathe once they lost the ball, snapping into a counter-press that turned loose possession straight back into pressure rather than a Chelsea break. It wasn’t the wall-to-wall high press Arsenal fans are used to seeing, mind — Chelsea’s goalkeeper simply lumped the ball long from almost every goal kick and took that option away.
Arteta’s real second-half message was more targeted: press high, go man for man on Chelsea’s build-up, and squeeze specifically down their weaker right flank. It worked well enough that Arteta made a point of praising his side’s aggression afterwards.
The Moment It Turned
Set pieces very nearly wrote the headline themselves. Two corners drew Chelsea’s goalkeeper into uncomfortable moments, and an Odegaard free-kick in the first half found Calafiori with real space in the box. Arsenal’s routine was obvious enough in hindsight: four bodies camped at the far post, Gabriel the one real central aerial threat, before the group swarmed the six-yard box the second the ball was in the air — hunting any loose knockdown, or simply making the goalkeeper second-guess whether to come and claim it.
In the end, though, neither of Arsenal’s goals came from a dead ball. Havertz and Odegaard both scored from open play, and both were gifted at least part of the chance by a Chelsea back-line that either sat too flat and too spread out, or was still shuffling across to get compact when the ball arrived.
Rogers’s opener, by contrast, was scrappier than any of it — a loose ball on the edge of the box after Arsenal failed to fully clear a free-kick, snapped up before anyone in yellow could close him down. It’s a reminder that this Arsenal vs Chelsea tactical breakdown isn’t just about the patterns — sometimes a game turns on nothing more than who reacts first to a second ball.
Chelsea’s own build-up, when they did have it for longer spells, looked considerably more assured than the score-line suggests: patient at the back, Neto and Hato busy up and down the flanks, Palmer dropping into pockets to lure Arsenal out before looking to spring the width or the space behind. It just wasn’t enough, in the end, to add to Rogers’s early strike.
The Lacroix-Havertz duel deserves a mention of its own, because it flipped from a defensive win for Chelsea into the goal that put Arsenal ahead for good. Once Lacroix committed to marking him step for step, Havertz stopped chasing the long ball and instead used the attention to drag his marker out of position — a dummy run here, a delayed one there — until the space he’d created was there for someone else to exploit, and, eventually, for Odegaard to finish.
What It Means
Chelsea’s night is best summed up by a stat Xabi Alonso will already be aware of: it was the first match since he took over without his side creating a single big chance, Joao Pedro largely left to fend for himself up front in the first half.
Alonso, for his part, sounded more pleased with how his team held that early Rogers lead for the first quarter of an hour than he was frustrated by the eventual defeat — though he still wants more patience on the ball from his group. Arteta’s read was simpler: it was the aggression after half-time, and the discipline of the man-marking plan, that won Arsenal the points.
Strip away the finer detail and this Arsenal vs Chelsea tactical breakdown comes down to a fairly old-fashioned football truth — Arsenal made fewer mistakes, punished the ones Chelsea did make, and had just enough control after the break to see out a 2-1 win that, on some of the second-half evidence, Chelsea will feel they didn’t entirely deserve to lose.
