✍️ Match Preview

Full Analysis

Stockhorn Arena plays host to FC Thun versus FC Sion in Super League, Regular Season - 18. Kick-off: Saturday 19 December 2026 at 16:00 UTC.

Form & Momentum

FC Thun have collected 0.80 PPG across 10 Super League outings this season: 2W 2D 6L. Last five: W L L W D. They are averaging 1.40 goals per game and conceding 2.90 — a modest attacking output that tempers optimism on the Over 2.5 market. However, 2.90 goals conceded per game is a concern — opposing attacks have exploited them regularly. 1 clean sheet from 10 outings provides some defensive foundation. Both teams have scored in 60% of their games — a high BTTS rate that carries real weight in the goals markets. FC Thun have played only a handful of Super League games so far this season, so this record also draws on matches from last season.

At home at Stockhorn Arena, FC Thun have gone 5W 2D 3L this season (10 games, 1.70 PPG). They are averaging 2.10 goals per home game — a prolific scoring rate in front of their own fans. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture. Their home PPG of 1.70 is noticeably stronger than their overall 0.80 — FC Thun are significantly better at Stockhorn Arena than their overall form suggests.

FC Sion's overall Super League record this term: 6W 2D 2L from 10 games (2.00 PPG). Last five: L W W L W. Their attacking form is sharp — 2.30 goals per game is a high-output rate that commands respect in the goals markets. 4 clean sheets in 10 outings (40%) underlines their defensive solidity. Both teams have scored in 60% of their games — a noteworthy BTTS rate that supports the Yes market. FC Sion have played only a handful of Super League games so far this season, so this record also draws on matches from last season.

On the road, FC Sion have gone 5W 2D 3L from 10 away fixtures this term (1.70 PPG). They are averaging 1.90 goals per away game — strong road scoring that makes them a threat even without home support. 4 clean sheets from 10 away games (40%) shows they are capable of shutting up shop on the road.

On a straight form reading, FC Sion are the stronger side — 1.20 PPG clear of the hosts (2.00 vs 0.80). Backing them with draw insurance is the conservative play if the outright away price appears short.

H2H Analysis

The head-to-head record is closely matched — FC Thun lead 3W to 1W over the last 4 encounters, with 0 draws, though neither side has established a commanding advantage.

Scoring has been limited when these teams have met. The 4 previous contests averaged 1.8 goals, making the Under 2.5 the historically backed angle in the goals market. The most recent clash, on 10 May 2026, ended 0–2 with FC Sion winning.

With a balanced win record and just 1.8 goals per game historically, the H2H points toward a tight, low-scoring contest. Under 2.5 goals has the strongest statistical grounding from the fixture history regardless of which side wins.

Trading Data

FC Thun goal-timing and half-time pattern breakdown (43 games, 21 at home): they score before half-time in 76% of fixtures in home games; when goalless at HT, a second-half goal follows 90% of the time; two or more arrive in the second half on 50% of those occasions; BTTS occurs in 67% of their matches (home games); Over 2.5 goals lands in 71% of games (home games); Over 3.5 in 46%.

FC Sion goal-timing and half-time pattern breakdown (43 games, 21 at away): they score before half-time in 81% of fixtures in away games; when goalless at HT, a second-half goal follows 56% of the time; BTTS occurs in 67% of their matches (away games); Over 2.5 goals lands in 67% of games (away games).

From a combined perspective, both sides have high BTTS rates — FC Thun 70% and FC Sion 54% — which reinforces the BTTS Yes angle from in-play data. The over/under 2.5 picture is inconclusive from the in-play data (FC Thun 74% | FC Sion 54%).

Poisson Model

The Poisson distribution model projects FC Thun 1.48 xG and FC Sion 1.99 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 Thun attack 0.816 / defence 1.110 | FC Sion attack 1.053 / defence 0.976. League average goals — home 1.859 / away 1.699. Data: 38 FC Thun games / 38 FC Sion games used (CurrentSeason).

Result probabilities: FC Thun 29% | Draw 22% | FC Sion 49%. Fair-value odds: FC Thun 3.45 | Draw 4.55 | FC Sion 2.04. FC Sion hold a narrow Poisson edge at 49% — the draw (22%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 67% | BTTS probability 67% | Total xG 3.47. Over 2.5 is the model's clear signal at 67% — a total xG of 3.47 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 67% reflects that both xG figures (1.48 / 1.99) are above the threshold where scoring blanks become the primary outcome — both sides are projected to find the net.

Final Verdict

FC Thun dominate the H2H record, yet FC Sion are the in-form side right now — historical edge versus current momentum creates a genuine dilemma.

Poisson rates FC Sion as the most likely outcome at 49% — moderate model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw probability of 22% warrants consideration of Double Chance or Draw No Bet on FC Sion if the outright odds are short. The opposing side holds a 29% win probability per the model — this is not a banker and should be staked accordingly.

The Poisson model projects 3.47 xG in total — Over 2.5 at 67% — marginal — conflicting signals confidence, supported by form averaging 3.7 goals per game — though H2H averaging only 1.8 goals per meeting points in the other direction.

Poisson assigns a 67% probability to BTTS Yes based on the attack/defence strength model. Form rates corroborate: FC Thun 60% | FC Sion 50% BTTS from recent games.
