Lazio 1-1 AS Roma – Result & Analysis

Poisson model rates Lazio at 38%, yet in-form AS Roma provide a compelling counter-argument — this Lazio vs AS Roma fixture contains genuine analytical tension.

✍️ Match Preview

Full Analysis

Stadio Olimpico plays host to Lazio versus AS Roma in Serie A (matchday 32). Kick-off: Sunday 13 April 2025 at 20:45 UK time.

Form

Lazio (all games): 4W 4D 2L across their last 10 — 1.60 PPG. Last five: W D L D W. Offensively they are averaging 1.50 goals per game, with 1.40 conceded. 2 clean sheets from 10 outings (20%). Both teams have scored in 70% of their games — a high BTTS rate that carries real weight in the goals markets.

Lazio's form when playing at home: 3W 5D 2L across their last 10 home games (1.40 PPG). At home they are averaging 1.70 goals scored and 1.60 conceded per game. Both teams have scored in 80% of their home games — an outstanding BTTS rate that is a key data point for this fixture.

AS Roma's record over their last 10 games: 8W 2D 0L (2.60 PPG). Last five: W W W W D. They are scoring at 1.50 per game and conceding 0.40. Defensively, 0.40 goals conceded per game is elite-level — a side this difficult to score against is a real threat to Over 2.5 and BTTS Yes. 6 clean sheets from 10 games (60%) is an exceptional defensive record — they are keeping clean sheets more often than not.

AS Roma away from home: 5W 2D 3L from their last 10 away games — 1.70 PPG on the road. Away from home they average 1.10 goals scored and 1.00 conceded per game. 4 clean sheets from their last 10 away games (40%) shows they are capable of shutting up shop on the road. Their away PPG of 1.70 is notably below their overall 2.60 — form away from home has been a clear weakness recently.

The travelling side arrive in better shape. AS Roma are 1.00 PPG clear of Lazio over their recent games (2.60 vs 1.60). Backing the visitors outright or on Draw No Bet are both valid approaches where the price allows.

H2H History

Neither side has dominated the 7 H2H matches in our data: 3 wins for Lazio, 3 for AS Roma and 1 draw — leaving the H2H largely neutral.

The 7 H2H matches in our data averaged 1.9 goals per game — a neutral rate that gives no strong lean on the goals market from the H2H alone. The most recent of those, on 5 Jan 2025, ended Lazio 0–2 AS Roma — a AS Roma win.

The head-to-head data offers no strong steer in either the result or goals markets. Form, the model and current market pricing should carry more weight for this fixture.

Trading Data

Lazio goal-timing and half-time pattern breakdown (last 69 games, 34 of them at home): at least one goal arrives before half-time in 62% of their matches in home games; when goalless at HT, a second-half goal follows 86% of the time; of the 28 games they led at half-time, they failed to win 32%; BTTS occurs in 56% of their matches (home games); Over 2.5 goals lands in 47% of games (home games).

AS Roma goal-timing and half-time pattern breakdown (last 69 games, 34 of them away): at least one goal arrives before half-time in 56% of their matches in away games; when goalless at HT, a second-half goal follows 83% of the time; of the 19 games they trailed at half-time, they recovered to draw or win 42%; BTTS occurs in 59% of their matches (away games); Over 2.5 goals lands in 50% of games (away games).

BTTS rates are mixed from the trading data — Lazio 56% versus AS Roma 56%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Lazio 52% | AS Roma 52%). There is an in-play dynamic worth noting: Lazio surrender their half-time lead 32% of the time, while AS Roma have come from behind at the break to draw or win in 42% of cases — a combination that makes laying the hosts at HT a potential angle.

Poisson Model

The Poisson distribution model projects Lazio 1.30 xG and AS Roma 1.18 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: Lazio attack 1.209 / defence 1.116 | AS Roma attack 0.920 / defence 0.861. League average goals — home 1.252 / away 1.146. Data: built from Lazio's last 69 games and AS Roma's last 69.

Result probabilities: Lazio 38% | Draw 30% | AS Roma 32%. Fair-value odds: Lazio 2.64 | Draw 3.30 | AS Roma 3.14. This is a low-confidence result — no outcome reaches 45%. The draw at 30% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 45% | BTTS Yes probability 52% | Total xG 2.48. Under 2.5 has a narrow probability edge at 55% — total xG of 2.48 is below the line but not decisively so. BTTS Yes at 52% is only a slight lean — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Final Verdict

Poisson rates Lazio as the most likely outcome at 38% — marginal model lean. Note a divergence: in-form AS Roma (2.60 PPG) cuts against the Poisson lean — the model adjusts for opposition strength, which raw form results do not. Draw probability of 30% warrants consideration of Double Chance or Draw No Bet on Lazio if the outright odds are short. The opposing side holds a 32% win probability per the model — this is not a banker and should be staked accordingly.

The Poisson model projects 2.48 xG in total — Under 2.5 at 55% — reasonable conviction, supported by the H2H data averaging 1.9 goals per game across 7 H2H matches.

Poisson assigns a 52% probability to BTTS Yes based on the attack/defence strength model. Form rates corroborate — both teams scored in: Lazio 80% (last 10 home games) | AS Roma 40% (last 10 away games).
