Pre-match analysis and preview

Verified historical context from before kickoff; preserved for comparison after the final result.

Portsmouth host Swansea City in Championship. This preview compares historical records dated before the prediction was locked with the model's pre-match probabilities. Probabilities describe estimated outcomes, not guaranteed results.

Across their last 5 recorded league matches, Portsmouth collected 10 points (3 wins, 1 draws and 1 losses). Swansea City earned 9 points from 5 matches (3 wins, 0 draws and 2 losses). These are separate recent-form samples, not a forecast of the final score.

At home, Portsmouth have 3 wins, 1 draws and 1 losses in their last 5 recorded home matches. On the road, Swansea City have 3 wins, 0 draws and 2 losses across 5 away matches.

Where full-quality xG is available, Portsmouth average 1.16 xG and 1.01 xGA over 5 recent matches; Swansea City average 1.24 xG and 1.61 xGA over 5 matches. xG coverage can be smaller than the recent-results sample.

At the prediction timestamp, the reconstructed league table places Portsmouth in position 11 and Swansea City in position 3. The table uses matches dated before the prediction timestamp; later backfills cannot be independently excluded.

The database contains 4 earlier head-to-head meetings in this competition, shown below. Historical meetings provide context, not certainty.

This analysis is based on available league records and the pre-match snapshot. Missing samples are not estimated; player availability, injuries and tactical claims are not inferred.

Post-match analysis

Final score, verified match data and the original model prediction.

Portsmouth won 3–1 against Swansea City. The following review separates the final score from the locked pre-match model forecast.

Expected goals were 1.25 for Portsmouth and 1.68 for Swansea City. Swansea City generated the higher xG total. Portsmouth scored +1.75 goals relative to xG and Swansea City scored -0.68 relative to xG. Goals minus xG is a descriptive difference, not proof of finishing skill or luck in one match.

Portsmouth registered 13 shots, with 5 on target (shot accuracy: 38.5%); Swansea City recorded 9 shots, with 3 on target (shot accuracy: 33.3%). Shot accuracy is shots on target divided by total shots, not a measure of chance quality.

The model's highest-probability 1X2 outcome was Home (41.4%); the actual outcome was Home, so the leading selection matched the result. The pre-match probabilities were not recalculated after the fixture.
