Form Guide
Cobresal — All Games: 4W 2D 4L from 10 Primera División outings this season, averaging 1.40 points per game. Last five: D W W L L. They are averaging 1.00 goals per game and conceding 1.20 — a modest attacking output that tempers optimism on the Over 2.5 market. 3 clean sheets from 10 outings provides some defensive foundation. This season is still relatively young for Cobresal, so this record blends games from this season and last.
Cobresal's form when playing at home: 5W 3D 2L across 10 games at Estadio El Cobre de El Salvador this term (1.80 PPG). At home they are averaging 1.60 goals scored and 1.00 conceded per game. Both teams have scored in 80% of their home games — an outstanding BTTS rate that is a key data point for this fixture.
Looking at all fixtures this season, Union La Calera stand at 2W 2D 6L from 10 Primera División matches — 0.80 PPG. Last five: L L L L D. Their scoring rate of 0.50 per game is modest, conceding 1.30 — not a side to back heavily on the Over 2.5 from their form alone. 2 clean sheets from 10 outings suggests some defensive organisation. Both teams have scored in just 30% of their games, reflecting a regular tendency to keep or record clean sheets. This season is still relatively young for Union La Calera, so this record blends games from this season and last.
Union La Calera away from home this season: 2W 2D 6L from 10 away games — 0.80 PPG on the road. Away from home they average 0.50 goals scored and 1.00 conceded per game. Away from home, both teams have scored in only 30% of games — a low rate that backs BTTS No when they travel.
Cobresal are in the better shape of the two on current Primera División data — 0.60 PPG ahead (1.40 vs 0.80). That form margin is the baseline of a sensible selection even before other signals are layered in.

Poisson Model
The Poisson distribution model projects Cobresal 1.21 xG and Union La Calera 0.81 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: Cobresal attack 0.952 / defence 1.007 | Union La Calera attack 0.727 / defence 0.853. League average goals — home 1.494 / away 1.105. Data: 49 Cobresal games / 50 Union La Calera games used (CurrentSeason).
Result probabilities: Cobresal 46% | Draw 30% | Union La Calera 25%. Fair-value odds: Cobresal 2.17 | Draw 3.33 | Union La Calera 4.00. Cobresal hold a narrow Poisson edge at 46% — the draw (30%) is close enough to merit draw-inclusive market consideration.
Goals markets: Over 2.5 probability 33% | BTTS probability 39% | Total xG 2.02. Under 2.5 is the strongly backed market at 67% probability — total xG of 2.02 sits well below the 2.5 threshold. The model is projecting a tight, low-scoring match based on both sides' defensive quality. BTTS probability of 39% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.
Summary & Verdict
The Poisson model's primary lean is Cobresal at 46% — moderate model lean. Current-season form corroborates the Poisson lean — partial multi-source support. With a 30% draw probability, Draw No Bet on Cobresal offers a more defensible entry point than the straight win.
Poisson projects 2.02 total expected goals, pointing to Under 2.5 at 33% probability — marginal — conflicting signals conviction, supported by form averaging 2.0 goals per game — though H2H averaging only 3.0 goals per meeting points in the other direction.
The Poisson model's BTTS call is No at 39%. Form rates are neutral: Cobresal 80% | Union La Calera 30%.
