Match Analysis
Union La Calera host Colo Colo at Estadio Municipal Nicolás Chahuán Nazar in Primera División, Regular Season - 18. Kick-off is scheduled for Wednesday 25 August 2021 at 21:30 UTC.
Recent Form
Across all Primera División games this season, Union La Calera have gone 6W 2D 2L from 10 outings — a 2.00 PPG return. Last five: W D W W L. They are averaging 1.20 goals per game and conceding 1.20 — a modest attacking output that tempers optimism on the Over 2.5 market. 5 clean sheets from 10 games (50%) is a standout defensive return — they are keeping their net clean in more than half their matches. This season is still relatively young for Union La Calera, so this record blends games from this season and last.
Union La Calera at Estadio Municipal Nicolás Chahuán Nazar this season: 6W 1D 1L from 8 home games — 2.38 PPG on home soil. At home they are averaging 1.25 goals scored and 0.88 conceded per game. 4 clean sheets from 8 home games (50%) — they are an exceptionally hard side to score against at Estadio Municipal Nicolás Chahuán Nazar.
Looking at all fixtures this season, Colo Colo stand at 7W 2D 1L from 10 Primera División matches — 2.30 PPG. Last five: W W W W W. They are scoring at 1.90 per game and conceding 0.50. Defensively, 0.50 goals conceded per game is elite-level — a side this difficult to score against is a real threat to Over 2.5 and BTTS Yes. 7 clean sheets from 10 games (70%) is an exceptional defensive record — they are keeping clean sheets more often than not. 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 Colo Colo, so this record blends games from this season and last.
Colo Colo's away record: 6W 1D 1L from 8 road trips in Primera División this season (2.38 PPG). They are averaging 2.00 goals per away game — strong road scoring that makes them a threat even without home support. 5 away clean sheets from 8 games (62%) — they are as difficult to score against on the road as they are at home.
There is minimal separation in the form figures — Union La Calera at 2.00 PPG versus Colo Colo's 2.30. The form guide is not providing a strong directional steer; the model and market data will carry more weight in the final assessment.
In-Play Data
Union La Calera trading profile (16 games, 8 at home): they score before half-time in 75% of fixtures in home games; when goalless at HT, a second-half goal follows 60% of the time; BTTS occurs in 50% of their matches (home games); Over 2.5 goals lands in 38% of games (home games); they keep a clean sheet 44% of the time.
Colo Colo trading profile (16 games, 8 at away): they score before half-time in 62% of fixtures in away games; when goalless at HT, a second-half goal follows 75% of the time; two or more arrive in the second half on 50% of those occasions; BTTS occurs in 38% of their matches (away games); Over 2.5 goals lands in 50% of games (away games); they keep a clean sheet 62% of the time.
BTTS rates are mixed from the trading data — Union La Calera 44% versus Colo Colo 38%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Union La Calera 44% | Colo Colo 38%).
Poisson Model
The Poisson distribution model projects Union La Calera 0.94 xG and Colo Colo 1.59 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: Union La Calera attack 0.949 / defence 1.131 | Colo Colo attack 1.190 / defence 0.931. League average goals — home 1.069 / away 1.182. Data: 16 Union La Calera games / 16 Colo Colo games used (CurrentSeason).
Result probabilities: Union La Calera 20% | Draw 29% | Colo Colo 51%. Fair-value odds: Union La Calera 5.00 | Draw 3.45 | Colo Colo 1.96. Colo Colo hold a narrow Poisson edge at 51% — the draw (29%) is close enough to merit draw-inclusive market consideration.
Goals markets: Over 2.5 probability 47% | BTTS probability 51% | Total xG 2.54. Over/Under 2.5 is close to a coin-flip at 47%/53% — the total xG of 2.54 sits near the 2.5 margin; this is a low-edge market from a Poisson standpoint. BTTS probability of 51% 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 Colo Colo at 51% — moderate model lean. With a 29% draw probability, Draw No Bet on Colo Colo offers a more defensible entry point than the straight win.
Poisson projects 2.54 total expected goals, pointing to Under 2.5 at 47% probability — Poisson-only — limited corroboration conviction.
The Poisson model's BTTS call is Yes at 51%. Form rates are neutral: Union La Calera 50% | Colo Colo 38%.

📝 Match Report
How It Unfolded
Union La Calera and Colo Colo finished level at 1-1 at Estadio Municipal Nicolás Chahuán Nazar, Regular Season - 18, in the Primera División. That is the final score; the rest of this report grades it against what the data forecast beforehand.
The Model vs The Result
The Poisson model went into this projecting Union La Calera 0.94 xG and Colo Colo 1.59 xG, a combined 2.54. The scoreboard read 1-1 for 2 actual goals. Both sides finished within a goal of their individual projections, so the scoreline sat close to the model's expected shape. Those figures were built on strength ratings of Union La Calera attack 0.95 / defence 1.13 against Colo Colo attack 1.19 / defence 0.93, drawn from 16/16 games (CurrentSeason).
On the result, the model split it Union La Calera 20% | Draw 29% | Colo Colo 51%, with Colo Colo to win its most likely call at 51%. The actual draw had been the model's second-ranked read at 29%, so the result diverged from the top call without being a shock.
Goals & Markets
The model rated Over 2.5 goals at 47%. The game delivered 2, so it stayed under — the model's lean was correct. Over 1.5 had been 74% and landed. On both teams to score, the model sat at 51% and the match saw both sides score — another call in the model's favour. Historically the two sides average 41% Over 2.5 across their same-competition games (Union La Calera 44%, Colo Colo 38%), a base rate that agreed with today's under. Their combined BTTS history runs at 41%, which did not match the both-scored outcome.
Trading Patterns vs Reality
Union La Calera's trading profile (16 games, 8 home) set some clear expectations: BTTS lands in 44% of their matches — today it did; they keep a clean sheet 44% of the time, and conceded here.
Colo Colo's trading profile (16 games, 8 away) set some clear expectations: BTTS lands in 38% of their matches — today it did; they keep a clean sheet 62% of the time, and conceded here.
Form vs Result
The form lines were close — Union La Calera 1.94 PPG, Colo Colo 2.06 PPG — offering no strong steer, and the draw fit that even billing. Colo Colo (home/away splits) managed 1 against a 2.00 scoring average — below par going forward.
Verdict
Grading the result against the stored data, 2 of 3 pre-match signals came in: result (miss), Over 2.5 (hit), BTTS (hit). A mixed scorecard — the data caught the broad shape of the game but not every market.
