Isidro Metapán vs Alianza: match statistics

Alianza appears to be the favorite based on season-long data: 24 wins and 73 goals scored versus Isidro Metapán’s 15 wins and 50 goals. Away, Alianza wins 59% of matches and averages 1.77 goals, while Isidro at home has a 47% win rate and scores 1.26 goals on average. Isidro at home generates slightly higher xG (1.43 vs 1.33) and more shots (10.16) and shots on target (5.05) per match compared to Alianza’s 9.36 and 4.05, but the visitors are significantly more efficient in chance conversion (19% conversion vs 12%) and have a lower share of goalless matches (18% vs 32%). Defensively, over the season Alianza concedes 0.86 goals on the road versus 1.21 conceded by Isidro at home, although in the last 5 matches Alianza has conceded 10 goals while scoring 9, indicating some instability. Considering the advantage in shot efficiency, win balance and goal difference (+20 away for Alianza vs +1 for the hosts), I forecast an away win: 50% probability, draw 25%, home 25%.

Both teams have seasonal BTTS rates of 55% (Isidro Metapán) and 50% (Alianza), with the last 5 matches showing 60% for the home side (3/5) and 80% for the away side (4/5), strongly favoring a 'both teams to score' scenario. xG analysis yields expected values of ~1.32 for Isidro (xG for 1.38 vs xG conceded 1.26) and 1.26 for Alianza (xG for 1.33 vs xG conceded 1.19); both above 1.2, so both sides have a realistic chance to score. In the last 5 matches Alianza scored 9 and conceded 10, while Isidro scored 5 and conceded 7; additionally the league average is 2.74 goals per match and seasonal goal totals are 50 for Isidro and 73 for Alianza, which supports a goal-rich scenario from both teams. For these reasons I tip BTTS - Yes with a probability of 70% vs 30% for No.

Expected goals are 1.32 for Isidro Metapán and 1.26 for Alianza (total 2.58), calculated as home xG 1.38 + away defense 1.26, and away xG 1.33 + home defense 1.19. In a Poisson model with λ=2.58 the probability of 2+ goals (Over 1.5) is about 73%, and 3+ goals (Over 2.5) about 48%. Seasonal stats confirm a scoring tendency: Isidro records Over 1.5 in 75% of matches, Alianza in 73%, while Over 2.5 occurs for hosts in 60% and for away sides in 50% of matches (league average 53% Over 2.5). In the last 5 matches Alianza scored 9 goals (1.8 avg) and has 80% of games Over 2.5, whereas Isidro scored 5 goals (1.0 avg) in their last 5 with 40% Over 2.5, suggesting the visitors are driving the higher total. Therefore the strongest and most reliable signal is Over 1.5 (Over) — high 73% probability and consistent seasonal rates of 75% and 73% for both teams give this line the greatest edge.

Alianza has a stronger profile at Half-Time and across the season: the visitors led at the break in 45% of their matches versus 35% for Isidro, they score on average 0.95 goals by Half-Time compared to 0.7 for the hosts, and average Half-Time points are 1.82 for Alianza versus 1.50 for Isidro. Over the full season Alianza averages 1.77 goals per match and concedes 0.86, while Isidro has 1.70 scored and 1.20 conceded; additionally the visitors have a higher average points per game (2.0 vs 1.85) and a higher win rate (59% vs 55%), which favors them to win after 90 minutes. A draw at Half-Time occurs frequently (around 45% of cases for both teams), and in the last five matches Alianza led at the break in 40% of games versus 0% for Isidro, which increases the likelihood of a scenario where the Half-Time score is a draw and the visitors complete a turnaround to win. Therefore I assign the highest probability to the X/2 variant (26%), the second most likely is 2/2 (23%), while 1/1 and 1/2 are less likely (1/1 — 11%, 1/2 — 4%), reflecting the hosts’ weaker starts and Alianza’s advantage in the closing stages of matches.
