Both clubs enter this Swiss Super League clash with contrasting recent form – Sion have been scoring freely, while Vaduz have struggled to find the net on the road. The fixture pits Sion's high‑scoring home record against Vaduz's leaky defense, setting the stage for a goal‑rich encounter.

Lars's Verdict

Strong
Over 2.5 goals Won Strong lean Strong · high xG

Back the over as the model assigns a 75.8% probability of more than 2.5 goals, far higher than a typical market pricing for this fixture.

Show the maths
The model gives FC Sion an expected 3.0 goals at home and FC Vaduz 1.0 away, summing to an average of four goals per game. Converting that combined xG to a probability yields a 75.8% chance of the total exceeding 2.5 goals. The market typically prices the over around 55‑60% for similar matchups, leaving a sizeable gap that the model exploits.
Pick 2 · Both Teams to Score
Both Teams to Score — Yes Won 59.8% model probability

With FC Sion averaging 3.0 expected goals and FC Vaduz averaging 1.0, the model gives a 59.8% chance both teams find the net, ahead of the 40.2% it gives to at least one side being kept out.

Show the maths
BTTS probability is derived from each side's expected goals (FC Sion 3.0, FC Vaduz 1.0) run through the same Poisson goal-expectancy model used for the match result: 59.8% of simulated outcomes have both teams scoring at least once, versus 40.2% where at least one side is shut out.
Pick 3 · Total Goals
Over 2.5 Goals Won 75.8% model probability

Combined expected goals of 4.0 (FC Sion 3.0 + FC Vaduz 1.0) points to an open game, with the model giving Over 2.5 Goals a 75.8% chance against 24.2% for Under.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (FC Sion 3.0 + FC Vaduz 1.0 = 4.0 combined): 75.8% of simulated outcomes finish with 3 or more goals, versus 24.2% finishing with 2 or fewer.
Match Result Model
