San Telmo vs Ciudad de Bolívar: match statistics

The favorites are the visitors Ciudad de Bolívar based on form and defense: they have 4 wins in their last 5 matches and average 2.4 points per game in that period, are still unbeaten away this season (loss percentage 0%) and keep 86% of matches with a clean sheet with only 0.14 average goals conceded on the road. San Telmo creates more chances at home (avg 14.29 shots, 5.43 shots on target and xG 1.80 per match), yet scores only 1.14 goals per game and has netted 2 goals in the last 5 fixtures. The efficiency gap is significant: Ciudad has a conversion rate of 12% versus the hosts’ 8% and a lower share of matches without scoring (29% vs 43%), translating into 6 away goals for Ciudad in the last 5 matches compared to 2 for San Telmo. Additionally, goal difference and away form favor the visitors (away goal difference +5 for Ciudad vs -1 for San Telmo), so I expect a Ciudad de Bolívar win.

Statistical analysis points to a 'No' scenario for BTTS - season BTTS rates are 33% for San Telmo and only 14% for Ciudad de Bolívar, and in the last 5 matches both teams have BTTS at 20%. A strong argument is the very high clean sheets: San Telmo kept a clean sheet in 67% of matches, Ciudad in 86%, and the league overall records clean sheets in 79% of games, which significantly reduces the probability of both teams scoring. Season average goals conceded are 0.83 (San Telmo) and 0.14 (Ciudad), while opposing xG (xG against) are 1.56 and 1.66; although attacking xG (xG_for) are 1.27 and 0.99, actual goals are low (0.83 and 0.86), meaning chances are not converting into goals. In the last 5 matches San Telmo scored 2 and conceded 1 (avg 0.4 and 0.2), Ciudad scored 6 and conceded 4 (avg 1.2 and 0.8), and matches over 2.5 goals occurred only 17% and 0% for home and away respectively, which confirms the low scoring. Summing the specific numbers — 67% and 86% clean sheets, season BTTS 33%/14% and recent BTTS 20%/20% — I assign an 80% probability to No BTTS and 20% to BTTS (Yes).

The xG-based model yields expected goals of ≈1.47 for San Telmo (xG attack 1.27 vs xG defense of Ciudad de Bolívar 1.66) and ≈1.28 for Ciudad de Bolívar (xG attack 0.99 vs xG defense of San Telmo 1.56), totaling ≈2.75 goals. A Poisson distribution with mean 2.75 indicates probability of at least 2 goals (Over 1.5) around 76%, while Over 2.5 is ~52% and Over 3.5 ~30%. Additionally, combined shots on target 2.17 (San Telmo) + 3.29 (Ciudad) = 5.46 and 6 away goals in the last 5 matches (avg 1.2) confirm chance creation. Although seasonally San Telmo has only 17% of matches over 2.5 goals and Ciudad 0%, the strongest and most reliable signal from the available data is a play on Over 1.5 (~76%).

I predict a Half-Time/Full-Time of draw at the break and away win (X/2). The visitors led at the break in 3 matches (43%) while the hosts led at the break in 0 (0%), indicating Ciudad de Bolívar more often leads or is level at half-time. Form and match parameters favor the visitors: 80% wins in the last 5 matches for the visitors versus 20% for the hosts and an average points per game of 2.14 versus 1.5; even though the hosts’ xG is 1.27 against the visitors’ 0.99, Ciudad de Bolívar registers more shots on target (3.29 vs 2.17) and a better conversion rate (12% vs 8%). There are generally few goals before the break (average 0.17 for the hosts and 0.43 for the visitors, with matches featuring an HT goal only 33%/43%), so a draw at half-time is logical. The second half is decisive: in the last 5 matches the visitors average 1.4 goals in second halves versus 0.2 for the hosts, and the visitors’ seasonal average of goals conceded after the break is only 0.14 (86% of matches without conceding in the second half), which strongly supports a turnaround in favor of the visitors after half-time.
