Pre-Match Analysis

Willem II and AZ Alkmaar meet at Koning Willem II Stadion in Eredivisie, Regular Season - 29. This fixture gets under way on Sunday 11 April 2027 at 15:00 UTC.

Form

Willem II (all games): 5W 2D 3L across 10 Eredivisie fixtures this term — 1.70 PPG. Last five: L W L L D. They are averaging 1.40 goals per game and conceding 1.50 — a modest attacking output that tempers optimism on the Over 2.5 market. 3 clean sheets from 10 outings provides some defensive foundation. Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets. 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 at home: 4W 3D 3L across 10 games at Koning Willem II Stadion this term (1.50 PPG). At home they are averaging 1.40 goals scored and 1.30 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture.

AZ Alkmaar's overall Eredivisie record this term: 6W 4D 0L from 10 games (2.20 PPG). Last five: D W W W W. Their attacking form is sharp — 2.40 goals per game is a high-output rate that commands respect in the goals markets. 5 clean sheets from 10 games (50%) is an exceptional defensive record — they are keeping clean sheets more often than not. 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 away from home: 4W 2D 4L across 10 road games this term (1.40 PPG). Away from home they average 1.20 goals scored and 1.30 conceded per game. Their away PPG of 1.40 is notably below their overall 2.20 — form away from home has been a clear weakness this season.

The travelling side arrive in better shape. AZ Alkmaar are 0.50 PPG clear of Willem II in recent Eredivisie fixtures (2.20 vs 1.70). Backing the visitors outright or on Draw No Bet are both valid approaches where the price allows.

H2H History

The head-to-head record is closely matched — Willem II lead 1W to 2W over the last 4 encounters, with 1 draws, though neither side has established a commanding advantage.

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 0–2 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 Data

Willem II goal-timing and half-time pattern breakdown (38 games, 19 at home): they score before half-time in 63% of fixtures in home 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 58% of their matches (home games); Over 2.5 goals lands in 47% of games (home games).

AZ Alkmaar goal-timing and half-time pattern breakdown (38 games, 19 at away): they score before half-time in 68% of fixtures in away 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 53% of their matches (away games); Over 2.5 goals lands in 53% of games (away games); Over 3.5 in 45%.

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

Poisson Model

The Poisson distribution model projects Willem II 1.13 xG and AZ Alkmaar 2.49 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: Willem II attack 0.889 / defence 1.273 | AZ Alkmaar attack 1.041 / defence 0.761. League average goals — home 1.674 / away 1.880. AZ Alkmaar's defence strength of 0.761 is below average — they are conceding at a rate that inflates the home xG figure. Data: 3 Willem II games / 38 AZ Alkmaar games used (CurrentSeason).

Result probabilities: Willem II 15% | Draw 18% | AZ Alkmaar 67%. Fair-value odds: Willem II 6.67 | Draw 5.56 | AZ Alkmaar 1.49. The model has a clear lean to AZ Alkmaar (67%) — a 52pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.

Goals markets: Over 2.5 probability 70% | BTTS probability 63% | Total xG 3.62. Over 2.5 is the model's clear signal at 70% — a total xG of 3.62 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 63% reflects that both xG figures (1.13 / 2.49) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Final Verdict

Poisson rates AZ Alkmaar as the most likely outcome at 67% — clear model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw No Bet is worth pricing alongside the outright: 18% draw probability makes the stalemate a live outcome even at this conviction level.

The Poisson model projects 3.62 xG in total — Over 2.5 at 70% — reasonable confidence, supported by H2H averaging 3.5 goals per meeting.

Poisson assigns a 63% probability to BTTS Yes based on the attack/defence strength model. Form rates corroborate: Willem II 60% | AZ Alkmaar 50% BTTS from recent games.
