They are averaging 1.40 goals per game and conceding 1.30 — a modest attacking output that tempers optimism on the Over 2.5 market. 4 clean sheets in 10 games (40%) reflects a solid defensive base.

At home they are averaging 1.60 goals scored and 0.60 conceded per game. 6 clean sheets from 10 home games (60%) — they are an exceptionally hard side to score against at Stade Geoffroy-Guichard. At home, both teams have scored in only 20% of games — reinforcing BTTS No as the home-venue-backed angle. Their home PPG of 2.00 is noticeably stronger than their overall 1.20 — Saint Etienne are significantly better at Stade Geoffroy-Guichard than their overall form suggests.

Trading

Saint Etienne half-time and goal-timing data (34 games, 17 at home): they score before half-time in 65% of fixtures in home games; when goalless at HT, a second-half goal follows 67% of the time; BTTS occurs in 41% of their matches (home games); Over 2.5 goals lands in 65% of games (home games).

Grenoble half-time and goal-timing data (34 games, 17 at away): they score before half-time in 71% of fixtures in away games; when goalless at HT, a second-half goal follows 62% of the time; BTTS occurs in 65% of their matches (away games); Over 2.5 goals lands in 47% of games (away games); they fail to score in 32% of games.

BTTS rates are mixed from the trading data — Saint Etienne 44% versus Grenoble 56%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Saint Etienne 56% | Grenoble 38%).

Poisson Model

The Poisson distribution model projects Saint Etienne 1.64 xG and Grenoble 1.07 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: Saint Etienne attack 1.212 / defence 0.911 | Grenoble attack 0.938 / defence 0.990. League average goals — home 1.369 / away 1.258. Data: 34 Saint Etienne games / 34 Grenoble games used (PrevSeason). Note: current-season sample is too small — prior-season data is carrying the calculation. Model confidence is reduced; treat probabilities as directional rather than precise.

Result probabilities: Saint Etienne 49% | Draw 27% | Grenoble 23%. Fair-value odds: Saint Etienne 2.04 | Draw 3.70 | Grenoble 4.35. Saint Etienne hold a narrow Poisson edge at 49% — the draw (27%) is close enough to merit draw-inclusive market consideration.

Goals markets: Over 2.5 probability 51% | BTTS probability 55% | Total xG 2.72. Over/Under 2.5 is close to a coin-flip at 51%/49% — the total xG of 2.72 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 55% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Verdict

The Poisson model's primary lean is Saint Etienne at 49% — moderate model lean. Draw probability of 27% warrants consideration of Double Chance or Draw No Bet on Saint Etienne if the outright odds are short.

The Poisson model projects 2.72 xG in total — Over 2.5 at 51% — Poisson-only — limited corroboration confidence.

Poisson assigns a 55% probability to BTTS Yes based on the attack/defence strength model. This conflicts with form data: Saint Etienne 20% | Grenoble 60% from recent games — a notable divergence.

The Poisson model is drawing on PrevSeason data (34 games minimum) — early-season projections carry additional uncertainty. Weight the live form and odds signals accordingly.
