✍️ 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 15:00 UTC.

Form

Willem II (all games): 1W 2D 7L across 10 Eredivisie fixtures this term — 0.50 PPG. Last five: D L L L L. They are averaging 1.10 goals per game and conceding 2.70 — a modest attacking output that tempers optimism on the Over 2.5 market. However, 2.70 goals conceded per game is a concern — opposing attacks have exploited them regularly. Both teams have scored in 80% of their matches — an extremely high rate that makes BTTS Yes a well-supported standalone angle from their form alone. This season is still relatively young for Willem II, so this record blends games from this season and last.

Willem II's form when playing at home: 4W 2D 4L across 10 games at Koning Willem II Stadion this term (1.40 PPG). At home they are averaging 1.30 goals scored and 1.40 conceded per game. Their home PPG of 1.40 is noticeably stronger than their overall 0.50 — Willem II are significantly better at Koning Willem II Stadion than their overall form suggests.

AZ Alkmaar's overall Eredivisie record this term: 6W 3D 1L from 10 games (2.10 PPG). Last five: W D W L D. Their attacking form is sharp — 2.30 goals per game is a high-output rate that commands respect in the goals markets. 3 clean sheets from 10 outings suggests some defensive organisation. Both teams have scored in 60% of their games — a noteworthy BTTS rate that supports the Yes market. This season is still relatively young for AZ Alkmaar, so this record blends games from this season and last.

AZ Alkmaar's form when playing away from home: 3W 3D 4L across 10 road games this term (1.20 PPG). Away from home they average 1.30 goals scored and 1.50 conceded per game. Their away PPG of 1.20 is notably below their overall 2.10 — form away from home has been a clear weakness this season.

The travelling side arrive in better shape. AZ Alkmaar are 1.60 PPG clear of Willem II in recent Eredivisie fixtures (2.10 vs 0.50). 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 5 encounters, with 2 draws, though neither side has established a commanding advantage.

These two sides have produced goals at a consistent rate historically, averaging 3.2 per game across 5 meetings. That scoring profile provides genuine support for the Over 2.5 angle. The most recent clash, on 11 Sep 2026, ended 1–1 with a draw.

With the win record balanced, the strongest H2H-derived signal is in the goals market. At 3.2 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 (43 games, 21 at home): they score before half-time in 62% 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 73% of those occasions; BTTS occurs in 52% of their matches (home games); Over 2.5 goals lands in 48% of games (home games).

AZ Alkmaar goal-timing and half-time pattern breakdown (43 games, 21 at away): they score before half-time in 71% 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 52% of their matches (away games); Over 2.5 goals lands in 52% of games (away games); Over 3.5 in 44%.

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 60%).

Poisson Model

The Poisson distribution model projects Willem II 0.95 xG and AZ Alkmaar 2.24 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 0.651 / defence 1.235 | AZ Alkmaar attack 1.019 / defence 0.859. League average goals — home 1.703 / away 1.782. Willem II's attack strength of 0.651 is below the league average — the 0.95 xG projection reflects a team that scores at a discount to the division norm. Data: 9 Willem II games / 42 AZ Alkmaar games used (CurrentSeason).

Result probabilities: Willem II 13% | Draw 22% | AZ Alkmaar 65%. Fair-value odds: Willem II 7.69 | Draw 4.55 | AZ Alkmaar 1.54. The model has a clear lean to AZ Alkmaar (65%) — a 52pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.

Goals markets: Over 2.5 probability 62% | BTTS probability 56% | Total xG 3.20. Over 2.5 holds a meaningful probability edge at 62% — the 3.20 total xG provides moderate support, though the model is not projecting a high-scoring game. BTTS probability of 56% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Final Verdict

Poisson rates AZ Alkmaar as the most likely outcome at 65% — clear model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw No Bet is worth pricing alongside the outright: 22% draw probability makes the stalemate a live outcome even at this conviction level.

The Poisson model projects 3.20 xG in total — Over 2.5 at 62% — strong confidence, supported by form averaging 2.8 goals per game and H2H averaging 3.2 goals per meeting.

Poisson assigns a 56% probability to BTTS Yes based on the attack/defence strength model. Form rates are neutral: Willem II 50% | AZ Alkmaar 50%.
