Robbo's Take

Headline Pick

Bayern Munich to win

Strong · clear superiority

Both Teams to Score

BTTS — Yes

68.5% model probability

Total Goals

Over 2.5 Goals

88.4% model probability

Both sides come in with contrasting recent runs – Bayern have a win and a draw in their last two league outings, while Union have managed a draw followed by two defeats.

Robbo's Verdict

Strong

Bayern Munich to win Strong · clear superiority

The model rates Bayern’s win probability at 83.5%, reflecting their superior expected goals and historical dominance over Union.

Show the maths

Bayern’s expected goals of 5.0 versus Union’s 1.35 creates a xG differential of 3.65, which the model translates into an 83.5% win probability for Bayern. The over‑2.5 goal probability of 88.4% further confirms a high‑scoring match, and the historic 4‑0 win adds weight to Bayern’s dominance. Together these figures drive the model’s strong confidence in a Bayern win.

Pick 2 · Both Teams to Score

Both Teams to Score — Yes 68.5% model probability

With Bayern München averaging 5.0 expected goals and Union Berlin averaging 1.35, the model gives a 68.5% chance both teams find the net, ahead of the 31.5% it gives to at least one side being kept out.

Show the maths

BTTS probability is derived from each side's expected goals (Bayern München 5.0, Union Berlin 1.35) run through the same Poisson goal-expectancy model used for the match result: 68.5% of simulated outcomes have both teams scoring at least once, versus 31.5% where at least one side is shut out.

Pick 3 · Total Goals

Over 2.5 Goals 88.4% model probability

Combined expected goals of 6.3 (Bayern München 5.0 + Union Berlin 1.35) points to an open game, with the model giving Over 2.5 Goals a 88.4% chance against 11.6% for Under.

Show the maths

Total goals probability comes from the same Poisson model summing both teams' expected goals (Bayern München 5.0 + Union Berlin 1.35 = 6.3 combined): 88.4% of simulated outcomes finish with 3 or more goals, versus 11.6% finishing with 2 or fewer.

Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has Bayern München at 83.5%, the draw at 5.7%, and Union Berlin at 4.1% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 4-1 at 6.1% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.

Form Guide — Last 5

Bayern München

Bayern’s last two league results are a 5‑1 home win over VfB Stuttgart and a 0‑0 draw away at FC Schalke 04. The win against Stuttgart showcases their attacking firepower, while the clean sheet against Schalke underlines defensive solidity, both supporting a Bayern victory.

Union Berlin

DLL

Union’s recent league form includes a 3‑3 home draw with Eintracht Frankfurt and a 0‑4 away loss to Bayer Leverkusen. Conceding four away goals highlights defensive frailties, and the high‑scoring draw shows limited offensive threat, reinforcing the expectation of a Bayern win.

Head-to-Head

In the most recent head‑to‑head, Bayern beat Union 4‑0 on 21 March 2026, a result that aligns with the model’s win prediction.
