✍️ Match Preview

Fixture Analysis

OH Leuven welcome Union St. Gilloise to Den Dreef in Jupiler Pro League (matchday 26). Kick-off is Saturday 20 March 2027 at 16:00 UK time.

Recent Form

Across their last 10 games, OH Leuven have gone 3W 3D 4L — a 1.20 PPG return. Last five: W D D W W. They are averaging 1.10 goals per game and conceding 1.40 — a modest attacking output that tempers optimism on the Over 2.5 market. 2 clean sheets from 10 outings (20%).

In front of their own supporters, OH Leuven have posted 3W 2D 5L from their last 10 home games — 1.10 PPG. At home they are averaging 1.10 goals scored and 1.40 conceded per game. At home, both teams have scored in only 30% of games — reinforcing BTTS No as the home-venue-backed angle.

Looking at their last 10 matches, Union St. Gilloise stand at 8W 2D 0L — 2.60 PPG. Last five: W D W W W. Their attacking form is sharp — 2.50 goals per game is a high-output rate that commands respect in the goals markets. Defensively, 0.60 goals conceded per game is elite-level — a side this difficult to score against is a real threat to Over 2.5 and BTTS Yes. 6 clean sheets from 10 games (60%) is an exceptional defensive record — they are keeping clean sheets more often than not.

Union St. Gilloise's away record over their last 10 away games: 7W 1D 2L (2.20 PPG). They are averaging 2.00 goals per away game — strong road scoring that makes them a threat even without home support. 4 clean sheets from their last 10 away games (40%) shows they are capable of shutting up shop on the road.

The form data does not support a straightforward home bias here. Union St. Gilloise are 1.40 PPG ahead (2.60 vs 1.20), making them the form-guided selection despite the trip.

Head to Head

Despite the home advantage, Union St. Gilloise have the better record in our head-to-head data — 7 wins from 10 H2H matches against 0 for OH Leuven.

The 10 H2H matches in our data averaged 2.7 goals per game — a neutral rate that gives no strong lean on the goals market from the H2H alone. The most recent of those, on 11 Oct 2026, ended OH Leuven 1–1 Union St. Gilloise — a draw.

Union St. Gilloise have the better head-to-head record despite being the visitors — 7 wins from 10 H2H matches. Home advantage alone is not a reason to dismiss that.

Trading Patterns

OH Leuven in-play and half-time data (last 51 games, 25 of them at home): at least one goal arrives before half-time in 64% of their matches in home games; when goalless at HT, a second-half goal follows 86% of the time; two or more arrive in the second half on 57% of those occasions; of the 12 games they led at half-time, they failed to win 58%; BTTS occurs in 44% of their matches (home games); Over 2.5 goals lands in 44% of games (home games); they fail to score in 33% of games.

Union St. Gilloise in-play and half-time data (last 51 games, 25 of them away): at least one goal arrives before half-time in 64% of their matches in away games; when goalless at HT, a second-half goal follows 62% of the time; of the 7 games they trailed at half-time, they recovered to draw or win 71%; BTTS occurs in 56% of their matches (away games); Over 2.5 goals lands in 44% of games (away games); they keep a clean sheet 49% of the time.

BTTS rates are mixed from the trading data — OH Leuven 49% versus Union St. Gilloise 45%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (OH Leuven 47% | Union St. Gilloise 45%). There is an in-play dynamic worth noting: OH Leuven surrender their half-time lead 58% of the time, while Union St. Gilloise have come from behind at the break to draw or win in 71% of cases — a combination that makes laying the hosts at HT a potential angle.

Poisson Model

The Poisson distribution model projects OH Leuven 1.06 xG and Union St. Gilloise 1.64 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: OH Leuven attack 0.876 / defence 0.910 | Union St. Gilloise attack 1.325 / defence 0.682. League average goals — home 1.765 / away 1.356. Union St. Gilloise bring a tight defence (rating 0.682, below 1 = concedes less than average) — this is pulling OH Leuven's projected output down. Union St. Gilloise have an above-average attack rating of 1.325, which lifts their away xG to 1.64. Data: built from OH Leuven's last 41 games and Union St. Gilloise's last 41.

Result probabilities: OH Leuven 24% | Draw 25% | Union St. Gilloise 51%. Fair-value odds: OH Leuven 4.08 | Draw 4.06 | Union St. Gilloise 1.97. Union St. Gilloise hold a narrow Poisson edge at 51% — the draw (25%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 50% | BTTS Yes probability 52% | Total xG 2.69. Over/Under 2.5 is close to a coin-flip at 50%/50% — the total xG of 2.69 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS Yes at 52% is only a slight lean — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Summary & Verdict

The Poisson model's primary lean is Union St. Gilloise at 51% — moderate model lean. Recent form and the head-to-head data both align with the Poisson read — multi-source corroboration increases confidence in this selection. With a 25% draw probability, Draw No Bet on Union St. Gilloise offers a more defensible entry point than the straight win.

On the goals line, Poisson's 2.69 combined xG gives a 50% probability to Over 2.5 — strong conviction, supported by recent form (OH Leuven's last 10 home games and Union St. Gilloise's last 10 away games) averaging 2.9 goals per game and the H2H data averaging 2.7 goals per game across 10 H2H matches.

Poisson assigns a 52% probability to BTTS Yes based on the attack/defence strength model. This conflicts with form data — both teams scored in: OH Leuven 30% (last 10 home games) | Union St. Gilloise 50% (last 10 away games), a notable divergence.
