Expected Goals & Probability Outlook
Every figure here comes from the same Dixon-Coles adjusted Poisson model, run on the scoring rates above.
| Market | Model probability |
|---|---|
| Bayer 04 Leverkusen win | 28.6% |
| Draw | 12.2% |
| 1. FC Union Berlin win | 59.3% |
| Both teams to score | 98.4% |
| Over 2.5 goals | 99.7% |
The likeliest exact scorelines are 4-5 at 3.3%, 4-6 at 3.2%, 3-5 at 3%. No single scoreline is ever likely in absolute terms — that is the nature of football — but the shape of the distribution is what the selections below are drawn from.
Published selections
- First Half Over 0.5 Goals: 1H Over 0.5 — 81% confidence. High goals-per-game metrics for both sides strongly support an early first-half breakthrough.
- Both Teams To Score (GG): GG (Yes) — 70% confidence. Given the 2-3 and 3-3 goals per game averages, both teams are expected to find the net.
- Over 2.5 Goals: Over 2.5 — 68% confidence. Both teams exhibit high-scoring early-season form averaging multiple goals conceded and scored per match.
- Over 2.5 Match Yellow Cards: Over 2.5 Cards — 65% confidence. Bundesliga matches featuring aggressive transition play frequently see at least three yellow cards.
- Over 8.5 Match Corners: Over 8.5 Corners — 62% confidence. Offensive playing styles from both clubs generally translate into sustained attacking pressure and corners.
- Most Scoring Half: 2nd Half — 53% confidence. Tactical adjustments and fatigue typically open up spaces in the second half for high-scoring teams.
- Match Winner: Home Win — 52% confidence. Leverkusen holds home advantage against Union Berlin, though both sides show defensive vulnerabilities early on.
- Match Outcome (W/D/L): Home Win — 52% confidence. Home-field advantage tips the scale in a match between two high-scoring, evenly matched outfits.
- Leading At Half Time: HT Home Win — 44% confidence. Leverkusen's home status gives them a slight edge to lead by halftime, though a draw is possible.
Score Prediction & Verdict
Prediction: 4-5 — an 1. FC Union Berlin win, and the likeliest scoreline within that result at 3.3%.
Confidence: Medium. The model puts an 1. FC Union Berlin win at 59.3%, with the draw at 12.2%.
The call rests on the scoring rates above holding up. It is wrong if this becomes the tight, low-event match the goals numbers argue against, and the margin here leaves less room for that than most.
