✍️ Match Preview

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 16:00 UTC.

Form

Willem II (all games): 8W 1D 1L across 10 Eredivisie fixtures this term — 2.50 PPG. Last five: D W W L W. Offensively they are averaging 1.60 goals per game, with 0.60 conceded. Defensively, conceding just 0.60 per game is an exceptional defensive record — one of the tightest in the division. 5 clean sheets from 10 games (50%) is a standout defensive return — they are keeping their net clean in more than half their matches. Willem II haven't played a Eredivisie game yet this season, so this record is entirely from last season.

Willem II's form when playing at home: 5W 2D 3L across 10 games at Koning Willem II Stadion this term (1.70 PPG). At home they are averaging 1.40 goals scored and 0.80 conceded per game. 4 home clean sheets from 10 games (40%) — a solid defensive base on their own ground. Somewhat surprisingly, their home PPG of 1.70 lags behind their overall 2.50 — the home advantage has not translated into superior results at Koning Willem II Stadion this season.

AZ Alkmaar's overall Eredivisie record this term: 3W 4D 3L from 10 games (1.30 PPG). Last five: W D D D D. They are scoring at 1.60 per game and conceding 1.30. 4 clean sheets in 10 outings (40%) underlines their defensive solidity. AZ Alkmaar haven't played a Eredivisie game yet this season, so this record is entirely from last season.

AZ Alkmaar's form when playing away from home: 2W 2D 6L across 10 road games this term (0.80 PPG). Away from home they average 0.90 goals scored and 1.70 conceded per game. Their away PPG of 0.80 is notably below their overall 1.30 — form away from home has been a clear weakness this season.

The form ledger tips toward Willem II. A 1.20 PPG lead over AZ Alkmaar (2.50 vs 1.30) is a consistent enough margin to carry weight. If the win odds appear compressed, Draw No Bet offers draw insurance at a lower cost than a full switch to Double Chance.

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 (34 games, 17 at home): they score before half-time in 65% 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 75% of those occasions; BTTS occurs in 53% of their matches (home games); Over 2.5 goals lands in 41% of games (home games).

AZ Alkmaar goal-timing and half-time pattern breakdown (34 games, 17 at away): they score before half-time in 71% of fixtures in away games; when goalless at HT, a second-half goal follows 88% of the time; BTTS occurs in 53% of their matches (away games); Over 2.5 goals lands in 53% of games (away games); Over 3.5 in 44%.

BTTS rates are mixed from the trading data — Willem II 53% versus AZ Alkmaar 65%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Willem II 53% | AZ Alkmaar 65%).

Poisson Model

The Poisson distribution model projects Willem II 1.40 xG and AZ Alkmaar 1.34 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 0.850 / defence 1.150 | AZ Alkmaar attack 0.893 / defence 0.911. League average goals — home 1.810 / away 1.308. Data: 0 Willem II games / 34 AZ Alkmaar games used (PrevSeason). Note: current-season sample is too small — prior-season data is carrying the calculation. Model confidence is reduced; treat probabilities as directional rather than precise.

Result probabilities: Willem II 35% | Draw 33% | AZ Alkmaar 32%. Fair-value odds: Willem II 2.86 | Draw 3.03 | AZ Alkmaar 3.12. This is a low-confidence result — no outcome exceeds 45%. The draw at 33% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 52% | BTTS probability 59% | Total xG 2.74. Over/Under 2.5 is close to a coin-flip at 52%/48% — the total xG of 2.74 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 59% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Final Verdict

Poisson rates Willem II as the most likely outcome at 35% — marginal model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw probability of 33% warrants consideration of Double Chance or Draw No Bet on Willem II if the outright odds are short. The opposing side holds a 32% win probability per the model — this is not a banker and should be staked accordingly.

The Poisson model projects 2.74 xG in total — Over 2.5 at 52% — reasonable confidence, supported by H2H averaging 3.5 goals per meeting.

Poisson assigns a 59% probability to BTTS Yes based on the attack/defence strength model. Form rates are neutral: Willem II 40% | AZ Alkmaar 50%.

The outsider holds a 32% win probability per the model — this is not a banker and should not be treated as one. Proportionate stakes are appropriate given the genuine contest the data projects. The Poisson model is drawing on PrevSeason data (0 games minimum) — early-season projections carry additional uncertainty. Weight the live form and odds signals accordingly.
