Full Analysis

Koning Willem II Stadion plays host to Willem II versus Fortuna Sittard in Eredivisie, Regular Season - 7. Kick-off: Saturday 19 September 2026 at 19:00 UTC.

Form & Momentum

Willem II have collected 1.70 PPG across 10 Eredivisie outings this season: 5W 2D 3L. 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.

In front of their own supporters this season, Willem II have posted 4W 3D 3L at Koning Willem II Stadion — 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.

Fortuna Sittard (all games): 3W 2D 5L across 10 Eredivisie outings this term — 1.10 points per game. Last five: L D W L W. Their scoring rate of 1.40 per game is modest, conceding 1.80 — not a side to back heavily on the Over 2.5 from their form alone. Both teams have scored in 70% of their games — a noteworthy BTTS rate that supports the Yes market. Fortuna Sittard have played only a handful of Eredivisie games so far this season, so this record also draws on matches from last season.

Fortuna Sittard away from home this season: 4W 1D 5L from 10 away games — 1.30 PPG on the road. Away from home they average 1.50 goals scored and 2.00 conceded per game. Both teams have scored in 80% of their away matches — a high BTTS rate on the road that directly informs this fixture.

Form favours the hosts. Willem II's 1.70 PPG return is 0.60 points per game ahead of Fortuna Sittard's 1.10 — a genuine gap in recent results that provides a statistically grounded case for backing the home side.

In terms of goals, both squads have been finding the net consistently (using home/away splits) — Willem II have seen both teams score in 60% of their games, Fortuna Sittard in 80%. That combined rate is a strong statistical case for BTTS Yes as a standalone play.

Head-to-Head

Neither side has dominated this fixture. The last 4 head-to-head meetings have produced 0 wins for Willem II, 2 for Fortuna Sittard and 2 draws — an even split that leaves the H2H largely neutral as a betting input.

Historically, goals have been at a premium in this fixture — just 1.0 per game from 4 meetings. The Under 2.5 has a clear base rate from the H2H record alone. The most recent clash, on 27 Apr 2025, ended 0–1 with Fortuna Sittard winning.

With a balanced win record and just 1.0 goals per game historically, the H2H points toward a tight, low-scoring contest. Under 2.5 goals has the strongest statistical grounding from the fixture history regardless of which side wins.

Trading

Willem II half-time and goal-timing data (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).

Fortuna Sittard half-time and goal-timing data (38 games, 19 at away): they score before half-time in 100% 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 100% of those occasions; BTTS occurs in 74% of their matches (away games); Over 2.5 goals lands in 68% of games (away games); Over 3.5 in 42%.

From a combined perspective, both sides have high BTTS rates — Willem II 58% and Fortuna Sittard 76% — 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% | Fortuna Sittard 68%).

Poisson Model

The Poisson distribution model projects Willem II 1.50 xG and Fortuna Sittard 2.54 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 0.888 / defence 1.271 | Fortuna Sittard attack 1.059 / defence 1.008. League average goals — home 1.677 / away 1.884. Data: 3 Willem II games / 38 Fortuna Sittard games used (CurrentSeason).

Result probabilities: Willem II 21% | Draw 19% | Fortuna Sittard 60%. Fair-value odds: Willem II 4.76 | Draw 5.26 | Fortuna Sittard 1.67. The model has a clear lean to Fortuna Sittard (60%) — a 39pp gap over the next-most-likely outcome reflects a meaningful statistical advantage.

Goals markets: Over 2.5 probability 77% | BTTS probability 72% | Total xG 4.04. Over 2.5 is the model's clear signal at 77% — a total xG of 4.04 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 72% reflects that both xG figures (1.50 / 2.54) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Verdict

Fortuna Sittard lead the H2H ledger, but Willem II carry stronger current form — do not let history alone dictate your assessment.

The Poisson model's primary lean is Fortuna Sittard at 60% — clear model lean. Note a divergence: in-form Willem II (1.70 PPG) cuts against the Poisson lean — consider the strength-adjusted model over surface-level form results. Draw No Bet is worth pricing alongside the outright: 19% draw probability makes the stalemate a live outcome even at this conviction level.

On the goals line, Poisson's 4.04 combined xG gives a 77% probability to Over 2.5 — marginal — conflicting signals, supported by form averaging 3.1 goals per game — though H2H averaging only 1.0 goals per meeting points in the other direction.

The Poisson model's BTTS call is Yes at 72%. Form rates corroborate: Willem II 60% | Fortuna Sittard 80% BTTS from recent games.
