Both Teams to Score

BTTS — Yes Lost

54.9% model probability

Total Goals

Over 2.5 Goals Won

50.6% model probability

Both clubs come into the game after a single recent league result – Leverkusen fell 2‑3 at SV Elversberg, while Union were held to a 3‑3 draw by Eintracht Frankfurt. The stark contrast to their season‑long goal expectations heightens the intrigue.

Robbo's Verdict

Lean

Both teams to score - Yes Lost Solid lean Lean · Slight edge

The model assigns a 54.9 % probability to both sides scoring, the highest confidence among the available markets.

Show the maths

Leverkusen’s xG of 1.35 matches Union’s 1.35, meaning the model expects each side to create roughly one clear chance. Converting those chances into scoring probabilities yields a BTTS chance of 54.9 %. The over/under line is split 50.6 % to 49.4 %, confirming that goal‑rich play is more likely than a low‑scoring affair. Because the BTTS probability is the strongest single figure, the model flags both teams to score as the headline pick.

Pick 2 · Both Teams to Score

Both Teams to Score — Yes Lost 54.9% model probability

With Bayer Leverkusen averaging 1.35 expected goals and Union Berlin averaging 1.35, the model gives a 54.9% chance both teams find the net, ahead of the 45.1% it gives to at least one side being kept out.

Show the maths

BTTS probability is derived from each side's expected goals (Bayer Leverkusen 1.35, Union Berlin 1.35) run through the same Poisson goal-expectancy model used for the match result: 54.9% of simulated outcomes have both teams scoring at least once, versus 45.1% where at least one side is shut out.

Pick 3 · Total Goals

Over 2.5 Goals Won 50.6% model probability

Combined expected goals of 2.7 (Bayer Leverkusen 1.35 + Union Berlin 1.35) points to an open game, with the model giving Over 2.5 Goals a 50.6% chance against 49.4% for Under.

Show the maths

Total goals probability comes from the same Poisson model summing both teams' expected goals (Bayer Leverkusen 1.35 + Union Berlin 1.35 = 2.7 combined): 50.6% of simulated outcomes finish with 3 or more goals, versus 49.4% finishing with 2 or fewer.

Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has Bayer Leverkusen at 37.1%, the draw at 25.8%, and Union Berlin at 37.1% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 1-1 at 12.2% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.

Form Guide — Last 5

Bayer Leverkusen

Leverkusen’s last league outing was a 2‑3 loss away to SV Elversberg (A), a match where they conceded three goals. That defeat, combined with the single‑game form label ‘L’, underlines a defensive frailty that makes a clean sheet unlikely, supporting the BTTS pick.

Union Berlin

Union Berlin’s most recent league result was a 3‑3 draw at home against Eintracht Frankfurt (H), showing they can both score and concede. The ‘D’ label reflects a balanced performance, reinforcing the view that Berlin will also get on the scoresheet.

Head-to-Head

In the five most recent meetings, Leverkusen have won three times (2‑0 on 2025‑10‑04, 2‑1 on 2024‑11‑30, 1‑0 on 2024‑04‑06), Union Berlin have won once (1‑0 on 2026‑02‑21) and there is one draw (0‑0 on 2025‑04‑12), a record that still favors both sides scoring.
