Full Analysis

Stadio Diego Armando Maradona plays host to Napoli versus Bologna in Serie A, Regular Season - 4. Kick-off: Sunday 13 September 2026 at 16:00 UTC.

Form

Napoli (all games): 5W 2D 3L across 10 Serie A fixtures this term — 1.70 PPG. Last five: L W W W L. Offensively they are averaging 1.50 goals per game, with 0.80 conceded. Defensively, conceding just 0.80 per game is an exceptional defensive record — one of the tightest in the division. 6 clean sheets from 10 games (60%) is a standout defensive return — they are keeping their net clean in more than half their matches. Both teams have scored in just 30% of their matches, indicating a tendency toward clean sheets or low-scoring outcomes. Napoli have played only a handful of Serie A games so far this season, so this record also draws on matches from last season.

At home at Stadio Diego Armando Maradona, Napoli have gone 6W 1D 3L this season (10 games, 1.90 PPG). At home they are averaging 1.70 goals scored and 1.20 conceded per game. BTTS has landed in 60% of their home matches — a rate that supports the Yes angle in this fixture.

Bologna's overall Serie A record this term: 4W 2D 4L from 10 games (1.40 PPG). Last five: W W D L L. Their scoring rate of 1.10 per game is modest, conceding 1.20 — not a side to back heavily on the Over 2.5 from their form alone. 3 clean sheets from 10 outings suggests some defensive organisation. Both teams have scored in just 30% of their games, reflecting a regular tendency to keep or record clean sheets. Bologna have played only a handful of Serie A games so far this season, so this record also draws on matches from last season.

When travelling in Serie A this season, Bologna have posted 7W 0D 3L from 10 away outings — 2.10 PPG. Away from home they average 1.50 goals scored and 1.20 conceded per game. Their away PPG of 2.10 exceeds their overall 1.40 — they actually perform better on the road than their aggregate form implies.

A near-identical PPG reading — 1.70 for Napoli, 1.40 for Bologna — means the form record is uninstructive on result selection. The goals and market sections will carry greater evidential weight.

Head-to-Head

Neither side has dominated this fixture. The last 10 head-to-head meetings have produced 4 wins for Napoli, 3 for Bologna and 3 draws — an even split that leaves the H2H largely neutral as a betting input.

These two sides have produced goals at a consistent rate historically, averaging 2.8 per game across 10 meetings. That scoring profile provides genuine support for the Over 2.5 angle. The most recent clash, on 11 May 2026, ended 2–3 with Bologna winning.

With the win record balanced, the strongest H2H-derived signal is in the goals market. At 2.8 goals per game historically, Over 2.5 is the cleaner angle to extract from the head-to-head data.

Trading Data

Napoli goal-timing and half-time pattern breakdown (40 games, 20 at home): they score before half-time in 80% of fixtures in home games; when goalless at HT, a second-half goal follows 67% of the time; they lead at the break 48% of the time; BTTS occurs in 60% of their matches (home games); Over 2.5 goals lands in 65% of games (home games); they keep a clean sheet 40% of the time.

Bologna goal-timing and half-time pattern breakdown (40 games, 20 at away): they score before half-time in 60% of fixtures in away games; when goalless at HT, a second-half goal follows 90% of the time; BTTS occurs in 55% of their matches (away games); Over 2.5 goals lands in 50% of games (away games); they fail to score in 32% of games.

BTTS rates are mixed from the trading data — Napoli 48% versus Bologna 42%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Napoli 52% | Bologna 42%).

Poisson Model

The Poisson distribution model projects Napoli 1.24 xG and Bologna 1.19 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: Napoli attack 1.102 / defence 1.026 | Bologna attack 0.938 / defence 0.960. League average goals — home 1.167 / away 1.233. Data: 40 Napoli games / 40 Bologna games used (Blended). A blend of current and prior-season data is applied to stabilise estimates early in the campaign.

Result probabilities: Napoli 37% | Draw 28% | Bologna 35%. Fair-value odds: Napoli 2.70 | Draw 3.57 | Bologna 2.86. This is a low-confidence result — no outcome exceeds 45%. The draw at 28% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 44% | BTTS probability 49% | Total xG 2.42. Under 2.5 has a narrow probability edge at 56% — total xG of 2.42 is below the line but not decisively so. BTTS probability of 49% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Verdict

The Poisson model's primary lean is Napoli at 37% — marginal model lean. Draw probability of 28% warrants consideration of Double Chance or Draw No Bet on Napoli if the outright odds are short. The opposing side holds a 35% win probability per the model — this is not a banker and should be staked accordingly.

On the goals line, Poisson's 2.42 combined xG gives a 44% probability to Under 2.5 — Poisson-only — limited corroboration — though H2H averaging only 2.8 goals per meeting points in the other direction.

The Poisson model's BTTS call is No at 49%. Form rates are neutral: Napoli 60% | Bologna 50%.

The outsider holds a 35% win probability per the model — this is not a banker and should not be treated as one. Proportionate stakes are appropriate given the genuine contest the data projects. The Poisson model is drawing on Blended data (40 games minimum) — early-season projections carry additional uncertainty. Weight the live form and odds signals accordingly.
