Our prediction before kickoff

We had Brentford 43% to win, 25% for a draw, Chelsea 32%. Brentford won: the pick was right. The final margin was 2.8 goals from ours; 9% of matches like this end further from the forecast than that.

Most of the distance between a forecast and a final score is luck: even with both clubs’ strength known exactly, a few shots decide a soccer match. This match was played before our forecasts went live, so this one was made afterwards, the same way, from only what was known before kickoff. How our predictions have done

The goals

Our source lists this match’s score but not who scored or when, so there is no timeline of it. The replay above needs only the score.

About these numbers

Scores and goals from openfootball (public domain). It has no shots, so there is no expected goals for this match and no finishing luck: the replay, the in-game win probability and the luck index are our own models, built from the season’s goals alone (methodology and validation). The luck index is how far the result was from what the goals say. Brentford win 67% of replays (a draw counted as half).
