Full Analysis

AFAS Stadion plays host to AZ Alkmaar versus Willem II in Eredivisie, Regular Season - 6. Kick-off: Friday 11 September 2026 at 18:00 UTC.

Current Form

AZ Alkmaar's overall Eredivisie record this term: 6W 4D 0L from 10 games (2.20 PPG). Last five: D W W W W. They are averaging 2.40 goals per game — a high-scoring output that makes them a genuine attacking threat in any fixture. 5 clean sheets from 10 games (50%) is a standout defensive return — they are keeping their net clean in more than half their matches. AZ Alkmaar have played only a handful of Eredivisie games so far this season, so this record also draws on matches from last season.

AZ Alkmaar's form when playing at home: 6W 3D 1L across 10 games at AFAS Stadion this term (2.10 PPG). They are averaging 2.60 goals per home game — a prolific scoring rate in front of their own fans. 4 home clean sheets from 10 games (40%) — a solid defensive base on their own ground. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture.

Willem II have collected 1.70 PPG across 10 Eredivisie outings this season: 5W 2D 3L. Last five: L W L L D. Their scoring rate of 1.40 per game is modest, conceding 1.50 — not a side to back heavily on the Over 2.5 from their form alone. 3 clean sheets from 10 outings suggests some defensive organisation. Both teams have scored in 70% of their games — a noteworthy BTTS rate that supports the Yes market. Willem II have played only a handful of Eredivisie games so far this season, so this record also draws on matches from last season.

Willem II's form when playing away from home: 8W 1D 1L across 10 road games this term (2.50 PPG). They are averaging 2.00 goals per away game — strong road scoring that makes them a threat even without home support. 5 away clean sheets from 10 games (50%) — they are as difficult to score against on the road as they are at home. Their away PPG of 2.50 exceeds their overall 1.70 — they actually perform better on the road than their aggregate form implies.

Form favours the hosts. AZ Alkmaar's 2.20 PPG return is 0.50 points per game ahead of Willem II's 1.70 — a genuine gap in recent results that provides a statistically grounded case for backing the home side.

H2H Analysis

Neither side has dominated this fixture. The last 4 head-to-head meetings have produced 2 wins for AZ Alkmaar, 1 for Willem II and 1 draws — an even split that leaves the H2H largely neutral as a betting input.

These two sides have produced goals at a consistent rate historically, averaging 3.5 per game across 4 meetings. That scoring profile provides genuine support for the Over 2.5 angle. The most recent clash, on 2 Feb 2025, ended 2–0 with AZ Alkmaar winning.

With the win record balanced, the strongest H2H-derived signal is in the goals market. At 3.5 goals per game historically, Over 2.5 is the cleaner angle to extract from the head-to-head data.

Trading

AZ Alkmaar half-time and goal-timing data (38 games, 18 at home): they score before half-time in 78% of fixtures in home games; when goalless at HT, a second-half goal follows 90% of the time; two or more arrive in the second half on 50% of those occasions; BTTS occurs in 72% of their matches (home games); Over 2.5 goals lands in 72% of games (home games); Over 3.5 in 45%.

Willem II half-time and goal-timing data (38 games, 18 at away): they score before half-time in 89% of fixtures in away games; when goalless at HT, a second-half goal follows 100% of the time; two or more arrive in the second half on 78% of those occasions; BTTS occurs in 56% of their matches (away games); Over 2.5 goals lands in 67% of games (away games).

From a combined perspective, both sides have high BTTS rates — AZ Alkmaar 63% and Willem II 58% — which reinforces the BTTS Yes angle from in-play data. The over/under 2.5 picture is inconclusive from the in-play data (AZ Alkmaar 63% | Willem II 58%).

Poisson Model

The Poisson distribution model projects AZ Alkmaar 3.00 xG and Willem II 1.29 xG. These expected goals figures are the primary input: they feed a goal-probability matrix across all scoreline combinations to derive the result and market probabilities below. Underlying strength ratings: AZ Alkmaar attack 1.352 / defence 0.859 | Willem II attack 0.801 / defence 1.325. League average goals — home 1.674 / away 1.880. AZ Alkmaar carry an above-average attack strength of 1.352 — their λ of 3.00 reflects genuine attacking quality above the league norm. Willem II bring a strong defensive rating of 1.325 — this is suppressing AZ Alkmaar's projected output below what their attack strength alone would suggest. Data: 38 AZ Alkmaar games / 3 Willem II games used (CurrentSeason).

Result probabilities: AZ Alkmaar 72% | Draw 15% | Willem II 13%. Fair-value odds: AZ Alkmaar 1.39 | Draw 6.67 | Willem II 7.69. The model has a clear lean to AZ Alkmaar (72%) — a 59pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.

Goals markets: Over 2.5 probability 80% | BTTS probability 69% | Total xG 4.29. Over 2.5 is the model's clear signal at 80% — a total xG of 4.29 means the expected score alone exceeds the 2.5 threshold, making the Over not just likely but structurally supported by both sides' attack/defence profiles. BTTS Yes at 69% reflects that both xG figures (3.00 / 1.29) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Verdict

The Poisson model's primary lean is AZ Alkmaar at 72% — clear model lean. Current-season form corroborates the Poisson lean — partial multi-source support.

Poisson projects 4.29 total expected goals, pointing to Over 2.5 at 80% probability — strong conviction, supported by form averaging 3.3 goals per game and H2H averaging 3.5 goals per meeting.

On the BTTS market, Poisson puts 69% on Yes. Form rates corroborate: AZ Alkmaar 60% | Willem II 50% BTTS from recent games.
