✍️ Match Preview
Fixture Analysis
It is a Super League clash, Regular Season - 21 as FC Sion welcome FC ST. Gallen to Stade de Tourbillon. Kick-off is set for Sunday 31 January 2027 at 13:00 UTC.
Recent Form
Across all Super League games this season, FC Sion have gone 6W 1D 3L from 10 outings — a 1.90 PPG return. Last five: W W W D L. They are averaging 2.30 goals per game — a high-scoring output that makes them a genuine attacking threat in any fixture. 2 clean sheets from 10 outings provides some defensive foundation. Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets. This season is still relatively young for FC Sion, so this record blends games from this season and last.
FC Sion's form when playing at home: 5W 4D 1L across 10 games at Stade de Tourbillon this term (1.90 PPG). They are averaging 2.00 goals per home game — a prolific scoring rate in front of their own fans. Both teams have scored in 70% of their home games — an outstanding BTTS rate that is a key data point for this fixture.
Looking at all fixtures this season, FC ST. Gallen stand at 5W 1D 4L from 10 Super League matches — 1.60 PPG. Last five: W L L W W. They are scoring at 1.70 per game and conceding 1.90. 2 clean sheets from 10 outings suggests some defensive organisation. Both teams have scored in 60% of their games — a noteworthy BTTS rate that supports the Yes market. This season is still relatively young for FC ST. Gallen, so this record blends games from this season and last.
FC ST. Gallen away from home this season: 6W 2D 2L from 10 away games — 2.00 PPG on the road. They are averaging 1.90 goals per away game — strong road scoring that makes them a threat even without home support. Both teams have scored in 80% of their away matches — a high BTTS rate on the road that directly informs this fixture.
The form comparison is too close to call — 1.90 PPG (FC Sion) versus 1.60 (FC ST. Gallen). When the figures are this level, no pick can be reliably derived from recent results alone.
Both teams score in over 70% of each side's relevant games (using home/away splits). At that combined rate, BTTS Yes is as well-evidenced as it gets — the data strongly backs two-way scoring.
H2H
The rivalry is an even one: 3 wins apiece for FC Sion, 3 for FC ST. Gallen and 4 shared spoils from 10 past contests. Neither side holds a meaningful historical edge.
Goals have been a feature of this fixture. The last 10 meetings have averaged 3.0 per game — a rate that gives the Over 2.5 market a solid historical foundation. The most recent clash, on 12 Sep 2026, ended 3–0 with FC Sion winning.
With the win record balanced, the strongest H2H-derived signal is in the goals market. At 3.0 goals per game historically, Over 2.5 is the cleaner angle to extract from the head-to-head data.
In-Play Profile
FC Sion in-play tendencies (48 games, 24 at home): they score before half-time in 79% of fixtures in home games; when goalless at HT, a second-half goal follows 56% of the time; BTTS occurs in 46% of their matches (home games); Over 2.5 goals lands in 42% of games (home games); Over 3.5 in 35%.
FC ST. Gallen in-play tendencies (48 games, 24 at away): they score before half-time in 75% of fixtures in away games; when goalless at HT, a second-half goal follows 80% of the time; two or more arrive in the second half on 70% of those occasions; BTTS occurs in 83% of their matches (away games); Over 2.5 goals lands in 71% of games (away games); Over 3.5 in 40%.
From a combined perspective, both sides have high BTTS rates — FC Sion 54% and FC ST. Gallen 71% — which reinforces the BTTS Yes angle from in-play data. The over/under 2.5 picture is inconclusive from the in-play data (FC Sion 56% | FC ST. Gallen 71%).
Poisson Model
The Poisson distribution model projects FC Sion 1.81 xG and FC ST. Gallen 1.57 xG. These expected goals figures are the primary input: they feed a goal-probability matrix across all scoreline combinations to derive the result and market probabilities below. Underlying strength ratings: FC Sion attack 1.015 / defence 0.849 | FC ST. Gallen attack 1.050 / defence 0.959. League average goals — home 1.864 / away 1.764. Data: 43 FC Sion games / 43 FC ST. Gallen games used (CurrentSeason).
Result probabilities: FC Sion 44% | Draw 23% | FC ST. Gallen 34%. Fair-value odds: FC Sion 2.27 | Draw 4.35 | FC ST. Gallen 2.94. This is a low-confidence result — no outcome exceeds 45%. The draw at 23% is a primary outcome, not an afterthought.
Goals markets: Over 2.5 probability 66% | BTTS probability 66% | Total xG 3.39. Over 2.5 is the model's clear signal at 66% — a total xG of 3.39 means the expected score alone exceeds the 2.5 threshold, making the Over not just likely but structurally supported by both sides' attack/defence profiles. BTTS Yes at 66% reflects that both xG figures (1.81 / 1.57) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.
Our Verdict
Poisson rates FC Sion as the most likely outcome at 44% — marginal model lean. With a 23% draw probability, Draw No Bet on FC Sion offers a more defensible entry point than the straight win. The opposing side holds a 34% win probability per the model — this is not a banker and should be staked accordingly.
On the goals line, Poisson's 3.39 combined xG gives a 66% probability to Over 2.5 — strong, supported by form averaging 3.2 goals per game and H2H averaging 3.0 goals per meeting.
Poisson assigns a 66% probability to BTTS Yes based on the attack/defence strength model. Form rates corroborate: FC Sion 70% | FC ST. Gallen 80% BTTS from recent games.
The outsider holds a 34% win probability per the model — this is not a banker and should not be treated as one. Proportionate stakes are appropriate given the genuine contest the data projects.
