Ajax v Excelsior Rotterdam

Eredivisie Matchweek 7 · Saturday 19 September 2026, 20:00 CEST (18:00 UTC) · Johan Cruijff ArenA

Match evidence and availability measured to the late afternoon of Wednesday 16 September 2026. Neither club has published a starting eleven, so no line-up is predicted below.

The FairEleven view

The balance points to an Ajax win, with medium confidence.

Ajax, fourth, host Excelsior, sixth, with a three-point gap between them after six matches each. The reason for the view is not Ajax's two most recent results, both 5-1. It is something steadier underneath them, and something about Excelsior that their ten points hide.

Everything here runs through expected goals, so a word on it first. Every shot can be scored for how likely it was to go in, given where it was taken from and what was around it. Add those up and you get a figure for how many goals a side's chances were worth. It is a count of chances, weighted by quality — not a prediction.

Ajax have not produced less than 1.97 in any league match this season. Excelsior's season splits cleanly on whether they win that count. In the four matches where they created more than their opponent, they created between 1.73 and 2.51 and took ten points. In the two where they did not, they created 0.66 and 0.91 and took nothing.

This fixture asks which of those two Excelsior sides Ajax produce. On the evidence, more likely the second. The risk to that view sits in the one part of Ajax's season that has gone wrong: defending at home.

Why

The central contest: Ajax's chance count against Excelsior's two profiles

Ajax's chance creation across six matches reads 2.09, 2.32, 2.17, 1.97, 3.82 and 3.29. That is four different opponents in the first four matches, two venues, three different results — and a floor that has not moved.

It also survived heavy rotation. Between Saturday's win at Fortuna Sittard and Tuesday's win over Willem II, Ajax changed six of their starting eleven — the goalkeeper, both full-backs and three of the six midfield and attacking places — and still created 3.29 after 3.82. Two matches is not proof of depth, but it is evidence that the chances do not depend on one particular eleven.

Excelsior are a different kind of side. In the matches they have controlled — away at SC Cambuur, at home to Sparta Rotterdam, away at Willem II and N.E.C. — they have been good, and the chances back it up. In the two they have not, they have been a long way short. At home to PSV, the only side above them they have met, they managed five shots and 0.66. At home to FC Utrecht, who are fourteenth, they managed 0.91 and lost to a stoppage-time goal.

That second defeat matters: this is not a side that only loses to strong teams. It is a side whose results follow whether it wins the chance count, and Ajax have won it against five of their six opponents.

Both head coaches have said what they want. Míchel wants the ball in the opponent's half and wants it back quickly and high when it is lost. Ruben den Uil has said his Excelsior never set up reactively and press high whatever the opponent. No match report this season describes either plan in action, and the two accounts of the Utrecht match disagree about how hard Excelsior pressed after half-time. None of the match data we hold shows where chances came from or how high either side pressed, so this is a contest of outcomes, not of channels. The clearest trace of Excelsior's two profiles is in the box: three shots from inside it against PSV, twelve against Sparta. What the outcomes say is conditional: if Excelsior come forward as their coach describes, they need to win the chance count to profit from it, and they have not yet done that against a side of Ajax's level.

Where Excelsior can genuinely hurt Ajax

Ajax have conceded six of their seven league goals at home. At the Johan Cruijff ArenA they have allowed 1.75 expected goals a match; away, 0.67. Their home opponents were sc Heerenveen, PSV and Willem II.

Excelsior are at their best away from home. They have taken seven of their ten points on the road and created 2.03 a match there, against 1.11 at home.

So each side's weaker record meets the other's stronger one. That is the most serious problem for our view and we would rather put it here than bury it. The honest size of it is small on both sides: three matches each, Ajax's home figure includes PSV, and Excelsior's away hosts sit tenth, fifteenth and seventeenth — one of them, N.E.C., reported to have changed their side ahead of European football.

Behind that sits the centre of Ajax's defence. Aaron Bouwman is out — the club has said so, naming this fixture. Thilo Kehrer and Youri Baas started together in the last two matches, both inside that absence, and Ajax allowed 0.69 and 1.23, the second partly after they had gone 4-0 up. Two starts together tell you who has been picked while Bouwman is injured. They do not tell you who Ajax prefer, and they do not tell you how the pairing handles a side that creates two a match away from home.

Which trends are real, and which are the noise

Ajax's last two results are the least reliable thing in their record. Ten goals came from chances worth 7.11.

There is a second measurement worth using here, one that scores a shot after it is struck, by where in the goal it was heading. Ajax's shots in those two matches were worth 9.34 once struck — so most of the extra goals came from where the ball was put, not from goalkeepers failing to stop it. In their first four matches the same step ran the other way: shots worth 8.55 before they were struck were worth only 8.17 afterwards. Two matches of excellent placement after four matches of ordinary placement is a run, not a new level. We are not calling it improved finishing, and we are not calling it luck. It is simply not something to build on.

The same goes for the idea that the two wins show Ajax have fixed their midfield. The bigger of the two controlling displays came against Willem II with Sofyan Amrabat on the bench until the 57th minute, so it cannot be credited to his arrival, and the other came against a side reported to be sitting in a five-man defence.

Excelsior have their own version. They have scored 13 from chances worth 9.40, and their shots were worth 10.81 once struck. So a little under half of the excess came from where the ball was put, and the rest from beyond even that. They have scored at least that after-the-strike figure in all six matches: a small excess each time, repeated, with no explanation on record.

What is durable is the chance count on both sides. In a match between two sides who have both scored above their chances, the excesses do not favour either team. Our view rests on the chance count and would stand without either excess continuing.

How availability changes the contest

For Ajax, Bouwman's absence removes a centre-back from a position the club's own record already calls its weakest, and it leaves the pairing question open rather than answered. Simon Adingra (ankle) and Daley Blind (back) are still listed as injured, with no return announced before the head coach's pre-match briefing; neither featured in the side that created 3.82 and 3.29.

For Excelsior, the picture is not clean — it is unknown. No current Excelsior player has an absence record; the one open record the club carries belongs to a player no longer in the squad, and we do not count it either way. Simon Janssen, who started at left-back through pre-season and at N.E.C., was reported by Rijnmond as struggling for fitness after the N.E.C. match and began the Utrecht match on the bench. The status of Noah Naujoks, the captain, is unresolved on every source we hold. Excelsior have published no availability update since 13 September.

Ajax arrive for their third league match in eight days, on four days' rest. Excelsior have had six. Five Ajax players started both of the last two matches. No one has reported on their condition, and Ajax's creation held through rotation last time.

What would change this view

Before kickoff. An Ajax team sheet with a centre-back pairing other than Kehrer and Baas would make the defensive question sharper, because nobody would then have seen that pair together at all. A confirmed Excelsior eleven with both Janssen and Naujoks would remove two of the unknowns on their side; a club statement ruling out Naujoks, the captain, whose status is entirely unknown, would matter more than confirmation of Janssen's reported knock.

During the match. Excelsior creating more than about 1.7 expected goals would mean they had found the version of themselves that has taken ten points, and would put the match where the venue records say it could go. Ajax winning the chance count and failing to score would mean we were right about the contest and wrong about the result.

Game state. If Ajax score first, Excelsior's record says they can respond but have not yet turned a deficit into points: both matches they trailed at half-time ended in defeat, and against Utrecht they came back level before conceding in stoppage time. They have also conceded late in each of their last two matches. If Excelsior score first, the picture changes more: they led at half-time three times and won all three, and Ajax's only defeat this season came in the one match they trailed at the interval. A dismissal or an early injury in the centre of Ajax's defence would override all of it.

The strongest case against us

That our steadiest number is less steady than it looks, and our key evidence about Excelsior is a single match.

Ajax's floor of 1.97 is real, but the two highest figures in their record came against Fortuna Sittard, who had been giving chances away all season, and Willem II, who are seventeenth. Strip those out and Ajax are a side creating a little over two a match — good, not overwhelming. And the claim that Excelsior shrink against a better opponent rests on one home match against PSV. Their other defeat was to a side below them.

Add the venue records above and a reader could reasonably call this open. If Excelsior arrive as the side that won at Cambuur and Willem II, nothing in Ajax's home record says they will be stopped — least of all a centre-back pairing that has only ever started together while Bouwman has been injured, playing its third match in eight days.

Market Lens

We compared our view with the market only after it was written. It agrees on the winner and goes further than we do on Ajax's goals.

The snapshot comes from a Dutch licensed operator on the afternoon of Thursday 17 September, with the result checked against a second, independent listing. With the operator's margin removed, it makes Ajax the winner about 76 per cent of the time (74 on the second listing). That is our direction too.

The difference is Ajax's own goal count. The market makes three or more Ajax goals slightly more likely than not, at about 57 per cent — in line with their scoring record of 19 goals in six. Their chance record says less: chances worth 2.53 a match at home and 2.61 overall, a rate at which three or more goals is slightly less likely than not. Ajax have created more than three only in the two 5-1 wins, whose extra goals we declined to build on above.

On total goals and goals at both ends the market sits inside our own scenarios, so we do not report a difference there. Nothing in this section changed the view above.

No score is predicted, and no probability is attached to any of the scenarios above.

The supporting evidence

Ajax — fourth, 13 points from six matches, 19 scored and seven conceded. 2-0 away at PEC Zwolle (chances worth 2.09 against 0.51), 2-2 at home to sc Heerenveen (2.32 against 1.61), 4-0 away at Telstar (2.17 against 0.82), 1-3 at home to PSV (1.97 against 2.41), 5-1 away at Fortuna Sittard (3.82 against 0.69), 5-1 at home to Willem II (3.29 against 1.23). That is 15.66 created and 7.26 allowed, or 2.61 and 1.21 a match. Two different public match feeds disagree about the chance figures for the Willem II match, and we use one consistent source for every match rather than picking between those two. No formation is stated for either side here: the data we hold shows the same Ajax eleven in two different shapes, and Ajax's head coach has said that playing systems do not much interest him.

Excelsior — sixth, ten points from six matches, 13 scored and seven conceded. 4-0 away at SC Cambuur (2.51 against 0.79), 1-2 at home to PSV (0.66 against 2.06), 2-1 at home to Sparta Rotterdam (1.75 against 0.87), 3-0 away at Willem II (1.73 against 1.18), 2-2 away at N.E.C. (1.84 against 1.21), 1-2 at home to FC Utrecht (0.91 against 1.48). That is 9.40 created and 7.60 allowed. In their last two matches they conceded four goals from shots worth 2.21 once struck. None of the chance figures for either club in this article includes a penalty.

Availability, and only what has actually been recorded. Ajax: Aaron Bouwman (bruised sternum and lung; the club has said he misses this match), Simon Adingra (ankle, since 3 September) and Daley Blind (back, since mid-August, no return date). Excelsior: no current absence record, one reported fitness doubt and one unresolved status, as above. Nobody at either club is treated as unavailable merely for being absent from a team sheet. No suspension is known for either side, and none is ruled out.
