H2H History

The head-to-head record in our data favours Union Berlin, who have won 3 of the 4 H2H matches we hold against FSV Mainz 05 — FSV Mainz 05 have 0 wins, with 1 draw.

The 4 H2H matches in our data averaged 2.5 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 4 Feb 2023, ended Union Berlin 2–1 FSV Mainz 05 — a Union Berlin win.

The head-to-head data gives Union Berlin an edge — 3 wins from 4 H2H matches is worth weighing, particularly if the form picture is inconclusive.

Trading Data

Union Berlin goal-timing and half-time pattern breakdown (last 34 games, 17 of them at home): at least one goal arrives before half-time in 59% of their matches in home games; when goalless at HT, a second-half goal follows 69% of the time; of the 9 games they trailed at half-time, they recovered to draw or win 33%; BTTS occurs in 53% of their matches (home games); Over 2.5 goals lands in 47% of games (home games).

FSV Mainz 05 goal-timing and half-time pattern breakdown (last 34 games, 17 of them away): at least one goal arrives before half-time in 88% of their matches in away games; when goalless at HT, a second-half goal follows 80% of the time; two or more arrive in the second half on 60% of those occasions; of the 12 games they led at half-time, they failed to win 33%; of the 12 games they trailed at half-time, they recovered to draw or win 25%; BTTS occurs in 65% of their matches (away games); Over 2.5 goals lands in 65% of games (away games); Over 3.5 in 35%.

BTTS rates are mixed from the trading data — Union Berlin 50% versus FSV Mainz 05 65%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Union Berlin 50% | FSV Mainz 05 65%). Note also that FSV Mainz 05 surrender HT leads in 33% of cases while Union Berlin recover from half-time deficits to draw or win 33% of the time — a dynamic that could influence in-play positioning.

Poisson Model

The Poisson distribution model projects Union Berlin 1.78 xG and FSV Mainz 05 1.13 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: Union Berlin attack 0.950 / defence 0.836 | FSV Mainz 05 attack 0.998 / defence 0.976. League average goals — home 1.919 / away 1.350. Data: built from Union Berlin's last 34 games and FSV Mainz 05's last 34. Some of those games are older results, so treat these probabilities as directional rather than precise.

Result probabilities: Union Berlin 52% | Draw 25% | FSV Mainz 05 23%. Fair-value odds: Union Berlin 1.93 | Draw 3.99 | FSV Mainz 05 4.32. Union Berlin hold a narrow Poisson edge at 52% — the draw (25%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 56% | BTTS Yes probability 57% | Total xG 2.90. Over 2.5 holds a meaningful probability edge at 56% — the 2.90 total xG provides moderate support, though the model is not projecting a high-scoring game. BTTS Yes at 57% is only a slight lean — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Final Verdict

Poisson rates Union Berlin as the most likely outcome at 52% — 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. Draw probability of 25% warrants consideration of Double Chance or Draw No Bet on Union Berlin if the outright odds are short.

On the goals line, Poisson's 2.90 combined xG gives a 56% probability to Over 2.5 — a Poisson-only call with no corroboration from form or H2H.

The Poisson model's BTTS call is Yes at 57%. Form rates are neutral — both teams scored in: Union Berlin 40% (last 10 home games) | FSV Mainz 05 60% (last 10 away games).

The Poisson model's sample (Union Berlin 34 games, FSV Mainz 05 34) includes some older results, so its projections carry extra uncertainty — weight recent form and the odds accordingly.
