Melgar vs Alianza Atlético: match statistics

I back Melgar to win (1) because they win 63% of home matches, score on average 2.0 goals per game and have a home goal differential of +9. Alianza Atlético win only 25% of away matches, concede 1.25 goals per game on the road, have a negative away goal differential of -2 and failed to score in 25% of away fixtures. In the last 5 matches Melgar scored 8 goals and averaged 1.6 points per game, while Alianza had 4 goals and 1.0 point per game, indicating the hosts’ superiority in finishing and form. Melgar converts chances far better (14% shot conversion at home vs 7% for Alianza away), with similar average xG (Melgar xG 1.47 vs Alianza xG 1.46), and the hosts also have 50% clean sheets at home compared to 13% for the visitors.

Melgar concedes only 0.63 goals at home on average and has a 50% clean sheet rate, while Alianza Atlético scores 1.00 goal away on average and has just a 13% clean sheet rate; this is a strong signal that the home side often finishes matches with a clean sheet. Alianza has scored 4 goals in the last 5 matches (0.8 per game) and posts a 7% shot conversion, limiting their realistic chance of breaking down Melgar’s solid defense. On the other hand, Melgar generates xG 1.54 versus Alianza’s average xG conceded of 1.32, and the hosts score 1.38 goals at home on average, so Melgar has the higher likelihood to score. Despite a league BTTS rate of 55% and 63% BTTS for Alianza away, the numerical balance (0.63 conceded at home and 50% CS vs 1.00 scored away and 13% CS) shifts the probability toward a No Goal outcome. Therefore I rate BTTS - No at 62% versus Yes at 38%.

Combining offensive and defensive xG yields expected goals: Melgar 1.43 (1.54 attacking xG vs opponent defensive xG 1.32), Alianza 1.29 (1.46 attacking xG vs Melgar defensive xG 1.11), total 2.72. The goal distribution with λ=2.72 implies P(≥2) ≈75.5% (hence Over 1.5 ≈76%), P(≥3) ≈51.1% (Over 2.5 ≈51%) and P(≥4) ≈29% (Over 3.5 ≈29%). Both teams produce many shots: averages 14.13 and 13.88 with 5.38 and 5.13 on target; Melgar has higher shot conversion 10% vs 7%, increasing the probability of home goals. Historically Over 1.5 occurred for Melgar in 50% of matches and for Alianza in 75%, while Over 2.5 is only 38% for both teams, which weakens confidence in the higher line. Therefore the strongest and most stable signal from the data is Over 1.5 (side: Over, line: 1.5).

I forecast a half-time draw and a Melgar victory at full-time (HT/FT = X/1). A draw at the break appears most likely: Melgar were level at half-time in 63% of home matches, and Alianza were drawing at half-time in 50% of away games, while home sides led at the break in only 25% of matches. Melgar, however, hold the advantage over the 90 minutes: goals per match 1.38 versus 1.00 for Alianza, higher xG 1.54 vs 1.46 and lower xG against 1.11 vs 1.32, indicating better quality of chances and a more consistent defense. Additionally, Melgar won 38% of home games compared with Alianza’s 25% away win rate, and in the last five fixtures hosts registered 40% wins versus 20% for visitors; therefore the half-time draw followed by a Melgar turnaround to win is the strongest signal.
