Both Teams to Score

BTTS — Yes Lost

77.7% model probability

Total Goals

Over 2.5 Goals Won

80.2% model probability

St. Gallen have been inconsistent at home, conceding as many as they score, while Sion have been prolific on the road, scoring twice per game on average. The fixture pits a side that can produce goals against a visitor that rarely keeps clean sheets.

Lars's Verdict

Strong

Both teams to score - Yes Lost Strong lean Strong · High BTTS probability

The model gives a 77.7% probability that both sides will hit the net, driven by their combined 4.3 expected goals and recent scoring patterns.

Show the maths

St. Gallen’s expected goals of 2.3 and Sion’s 2.0 combine to a total of 4.3, well above the 2.5 threshold that typically yields a BTTS outcome. The model’s BTTS probability of 77.7% reflects this gap. Moreover, each team’s recent matches show multiple goals scored—St. Gallen’s 3‑2 win and 2‑2 draw, Sion’s 3‑0 and 3‑2 wins—reinforcing the likelihood that both will score again. Hence the model’s high confidence in BTTS.

Pick 2 · Both Teams to Score

Both Teams to Score — Yes Lost 77.7% model probability

With FC ST. Gallen averaging 2.3 expected goals and FC Sion averaging 2.0, the model gives a 77.7% chance both teams find the net, ahead of the 22.3% it gives to at least one side being kept out.

Show the maths

BTTS probability is derived from each side's expected goals (FC ST. Gallen 2.3, FC Sion 2.0) run through the same Poisson goal-expectancy model used for the match result: 77.7% of simulated outcomes have both teams scoring at least once, versus 22.3% where at least one side is shut out.

Pick 3 · Total Goals

Over 2.5 Goals Won 80.2% model probability

Combined expected goals of 4.3 (FC ST. Gallen 2.3 + FC Sion 2.0) points to an open game, with the model giving Over 2.5 Goals a 80.2% chance against 19.8% for Under.

Show the maths

Total goals probability comes from the same Poisson model summing both teams' expected goals (FC ST. Gallen 2.3 + FC Sion 2.0 = 4.3 combined): 80.2% of simulated outcomes finish with 3 or more goals, versus 19.8% finishing with 2 or fewer.

Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has FC ST. Gallen at 45.7%, the draw at 19.7%, and FC Sion at 34.5% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 2-1 at 7.2% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.

Form Guide — Last 5

FC ST. Gallen

WDLL

St. Gallen’s last five league results are W‑D‑L‑L, highlighted by a 3‑2 away win over Vaduz and a 2‑2 home draw with Luzern. The win and draw demonstrate they can score multiple goals, while the two losses show defensive frailties, supporting a BTTS outcome.

FC Sion

WWLW

Sion’s recent run of W‑W‑L‑W shows three wins in four games, including a 3‑0 home thrashing of Luzern and a 2‑1 away win at Basel 1893. Their ability to find the net even when away, combined with conceding in the 1‑2 loss to Lugano, underlines a strong chance of both sides scoring.

Head-to-Head

In the five most recent meetings, Sion have won twice (0‑3 and 3‑2) and drawn twice (both 1‑1), with St. Gallen securing a 3‑1 win. The mixed results, especially the high‑scoring encounters, support the BTTS pick.
