Robbo's Verdict

Strong
FSV Mainz 05 to win Strong lean Strong · Clear win odds

With a 63.4% win probability and a defensive record that concedes four per game, Mainz are the clear favourites.

Show the maths
The model assigns Mainz a 5.0 expected goals versus Gladbach's 3.0, creating a two‑goal advantage. Combined with Gladbach’s 4.0 goals‑against average and Mainz’s zero away goals‑against, the win probability rises to 63.4%. This gap translates directly into a strong confidence in a Mainz victory.
Pick 2 · Both Teams to Score
Both Teams to Score — Yes 87.6% model probability

With Borussia Mönchengladbach averaging 3.0 expected goals and FSV Mainz 05 averaging 5.0, the model gives a 87.6% chance both teams find the net, ahead of the 12.4% it gives to at least one side being kept out.

Show the maths
BTTS probability is derived from each side's expected goals (Borussia Mönchengladbach 3.0, FSV Mainz 05 5.0) run through the same Poisson goal-expectancy model used for the match result: 87.6% of simulated outcomes have both teams scoring at least once, versus 12.4% where at least one side is shut out.
Pick 3 · Total Goals
Over 2.5 Goals 91.5% model probability

Combined expected goals of 8.0 (Borussia Mönchengladbach 3.0 + FSV Mainz 05 5.0) points to an open game, with the model giving Over 2.5 Goals a 91.5% chance against 8.5% for Under.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (Borussia Mönchengladbach 3.0 + FSV Mainz 05 5.0 = 8.0 combined): 91.5% of simulated outcomes finish with 3 or more goals, versus 8.5% finishing with 2 or fewer.
