Bastia vs Saint-Étienne: match statistics

I predict an away win (pick '2'): Saint-Étienne sit 2nd in the table while Bastia are 18th, clearly reflecting a class gap. The visitors have scored 53 goals this season versus the hosts' 19; in the last 5 matches Saint-Étienne have 9 goals scored and 2 conceded, Bastia 7 scored and 9 conceded; average points per game over the last 5 is 2.2 for the visitors vs 0.6 for the hosts. Bastia’s home scoring efficiency is poor — only 0.57 goals per game on average with xG 1.46 and a 4% conversion rate, and in 50% of home matches the hosts failed to score; Saint-Étienne away average is 1.27 goals with xG 1.42, 10% conversion and in 33% of away matches they failed to score. Defensively the visitors also fare better: Bastia concede 1.29 goals at home versus 1.07 conceded by Saint-Étienne away, and Bastia’s home goal difference is -10 compared to the visitors’ +3 on the road. Summing these indicators — goals (53 vs 19), conversion (10% vs 4%), form points (2.2 vs 0.6) and goal difference (+3 vs -10) — I assess the visitors’ chances as significantly higher.

Bastia scores on average 2.27 goals per match this season and has BTTS at 53%, while in the last 5 matches BTTS occurred in 80% (7 goals scored and 9 conceded in those 5), which is a strong signal in favor of both teams scoring. Saint-Étienne has a seasonal BTTS of 40% and also 40% in the last 5 matches, but in those 5 fixtures they scored 9 goals (1.8 avg) and conceded only 2 goals (0.4 avg), which indicates very good recent defense and reduces the likelihood that they will concede. Bastia generates xG 1.60 per match, averages 14.53 shots with 5.13 on target and has a conversion rate of 16%, while Saint-Étienne has xG 1.42, 12.07 shots with 4.6 on target and a conversion rate of 10%, so the hosts have an advantage in creating and finishing chances. Seasonally both teams concede similarly (Bastia 1.00 vs Saint-Étienne 1.07 avg), but the form distribution over the last 5 (Bastia concedes 1.8 vs Saint-Étienne 0.4) means a higher risk of conceding applies to Bastia, which supports the BTTS scenario. The balance of signals (Bastia 80% BTTS vs Saint-Étienne 40%, plus the hosts' offensive advantage) gives me an edge for "yes", therefore I rate BTTS at 60% vs 40% and pick the "yes" tip.

Based on xG I calculate expected goals: Bastia 1.45 = (1.60 + 1.29)/2, Saint-Étienne 1.25 = (1.42 + 1.07)/2, total 2.70 expected goals. A Poisson model with λ=2.70 yields roughly a 75% chance of Over 1.5 (P(0–1) ≈24.8%), about 51% for Over 2.5 and about 29% for Over 3.5. Seasonal stats support this: Bastia at home has Over1.5 in 80% of matches and Over2.5 in 67%, Saint-Étienne away has Over1.5 in 60% and Over2.5 in 47%, which further increases the probability of more than 1.5 goals. Bastia averages 2.27 goals at home and has a conversion rate of 16% versus 10% for opponents and 5.13 shots on target vs 4.6 for Saint-Étienne, boosting scoring potential; on the other hand Saint-Étienne in the last 5 matches averages 1.8 goals scored and concedes 0.4, which limits the chance of a very high-scoring game. As a result, the strongest and safest signal from the data is Over 1.5 (recommendation: Over, line 1.5) with an estimated probability of 75%.

Bastia has been the favorite from the outset: they led at the break in 7 matches (47%) and average 1.2 goals by half-time versus 0.67 for Saint-Étienne, with 26 half-time goals for the hosts compared to 17 for the visitors. Seasonal indicators support this picture — Bastia scores on average 2.27 goals per match with xG 1.60 and a shot conversion rate of 16%, while Saint-Étienne has 1.27 goals, xG 1.42 and a 10% conversion; the hosts also collect 27 points at the break vs 19 for their opponents (an average of 1.8 points per match at half-time vs 1.27). In the second half Bastia remain offensively active: second-half goals for the hosts average 1.07 versus 0.6 for Saint-Étienne and points earned after the break are 1.87 vs 1.47, which increases the chance of maintaining or extending a lead. Nevertheless, the risk of a turnaround by the visitors must be considered — Saint-Étienne are in better form over the last 5 matches (60% wins vs 0% for Bastia) and concede only 0.4 goals on average in their last 5 games compared to 1.8 for Bastia, so scenarios with a draw at half-time or an equalizer in the second half are not unlikely. Therefore my most confident pick is 1/1 (Bastia leading at the break and winning), but I retain significant probability on X/1 and 1/X given the visitors' form.
