Full Analysis
Stadion An der Alten Försterei plays host to Union Berlin versus FSV Mainz 05 in Bundesliga, Regular Season - 1. Kick-off: Sunday 20 August 2023 at 14:30 UTC.
Form & Momentum
Union Berlin have collected 1.70 PPG across 10 Bundesliga outings this season: 5W 2D 3L. Last five: D L W L W. Offensively they are averaging 1.50 goals per game, with 1.00 conceded. 5 clean sheets from 10 games (50%) is a standout defensive return — they are keeping their net clean in more than half their matches. Union Berlin haven't played a Bundesliga game yet this season, so this record is entirely from last season.
At home at Stadion An der Alten Försterei, Union Berlin have gone 6W 4D 0L this season (10 games, 2.20 PPG). At home they are averaging 1.60 goals scored and 0.50 conceded per game. 6 clean sheets from 10 home games (60%) — they are an exceptionally hard side to score against at Stadion An der Alten Försterei. Their home PPG of 2.20 is noticeably stronger than their overall 1.70 — Union Berlin are significantly better at Stadion An der Alten Försterei than their overall form suggests.
FSV Mainz 05's overall Bundesliga record this term: 2W 4D 4L from 10 games (1.00 PPG). Last five: L L L L D. They are scoring at 1.50 per game and conceding 2.00. Conceding 2.00 per game is a high rate — their defensive vulnerabilities have been exposed regularly this season. 1 clean sheet from 10 outings suggests some defensive organisation. Both teams have scored in 70% of their games — a noteworthy BTTS rate that supports the Yes market. FSV Mainz 05 haven't played a Bundesliga game yet this season, so this record is entirely from last season.
FSV Mainz 05's form when playing away from home: 2W 4D 4L across 10 road games this term (1.00 PPG). Away from home they average 1.20 goals scored and 1.60 conceded per game. BTTS has landed in 60% of their away games — meaningful support for the Yes angle in this specific context.
The form ledger tips toward Union Berlin. A 0.70 PPG lead over FSV Mainz 05 (1.70 vs 1.00) is a consistent enough margin to carry weight. If the win odds appear compressed, Draw No Bet offers draw insurance at a lower cost than a full switch to Double Chance.
H2H History
The head-to-head record favours Union Berlin, who have won 3 of the last 4 meetings against FSV Mainz 05 — a 1D 0W return for the visitors.
The 4 previous meetings have averaged 2.5 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 4 Feb 2023, ended 2–1 with Union Berlin winning.
The historical record gives Union Berlin a meaningful edge here — 3 wins from 4 meetings is the kind of ledger that should not be discounted when the form picture is inconclusive. Even away from home, the visitors have struggled to impose themselves in this fixture.
Trading Data
Union Berlin goal-timing and half-time pattern breakdown (34 games, 17 at home): they score before half-time in 59% of fixtures in home games; when goalless at HT, a second-half goal follows 69% of the time; 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 (34 games, 17 at away): they score before half-time in 88% of fixtures 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; 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%).
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: 34 Union Berlin games / 34 FSV Mainz 05 games used (PrevSeason). Note: current-season sample is too small — prior-season data is carrying the calculation. Model confidence is reduced; treat probabilities as directional rather than precise.
Result probabilities: Union Berlin 52% | Draw 25% | FSV Mainz 05 23%. Fair-value odds: Union Berlin 1.92 | Draw 4.00 | FSV Mainz 05 4.35. 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 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 probability of 57% is moderate — 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. Current-season form corroborates the Poisson lean — partial multi-source support. 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 — Poisson-only — limited corroboration.
The Poisson model's BTTS call is Yes at 57%. Form rates are neutral: Union Berlin 40% | FSV Mainz 05 60%.
The Poisson model is drawing on PrevSeason data (34 games minimum) — early-season projections carry additional uncertainty. Weight the live form and odds signals accordingly.

📝 Match Report
How It Unfolded
Union Berlin beat FSV Mainz 05 4-1 at Stadion An der Alten Försterei, Regular Season - 1, in the Bundesliga. With the result on the board, the sections below measure it against everything the model and the numbers projected in advance.
The Model vs The Result
The Poisson model went into this projecting Union Berlin 1.78 xG and FSV Mainz 05 1.13 xG, a combined 2.90. The scoreboard read 4-1 for 5 actual goals. Union Berlin beat their projection by 2.2 — clinical relative to the chances the model priced in. Those figures were built on strength ratings of Union Berlin attack 0.95 / defence 0.84 against FSV Mainz 05 attack 1.00 / defence 0.98, drawn from 34/34 games (PrevSeason).
On the result, the model split it Union Berlin 52% | Draw 25% | FSV Mainz 05 23%, with Union Berlin to win its most likely call at 52%. That is exactly how it finished — the model's leading outcome was vindicated.
Goals & Markets
The model rated Over 2.5 goals at 56%. The game delivered 5, so it went over — a call the model got right. Over 1.5 had been 80% and landed. Over 3.5 was 33% and came in. On both teams to score, the model sat at 57% and the match saw both sides score — another call in the model's favour. Historically the two sides average 57% Over 2.5 across their same-competition games (Union Berlin 50%, FSV Mainz 05 65%), a base rate that agreed with today's over. Their combined BTTS history runs at 57%, which matched the both-scored outcome.
Trading Patterns vs Reality
Union Berlin's trading profile (34 games, 17 home) set some clear expectations: BTTS lands in 50% of their matches — today it did; they keep a clean sheet 38% of the time, and conceded here.
FSV Mainz 05's trading profile (34 games, 17 away) set some clear expectations: BTTS lands in 65% of their matches — today it did.
Form vs Result

Union Berlin (home/away splits) scored 4 against a 1.76 average — above their attacking norm. FSV Mainz 05 (home/away splits) shipped 4 against a 1.76 concession average — a leakier day than usual.
Verdict
