Prediction conclusion

The model's leading selection is Draw/Away, at 66.1%. Its single most likely scoreline is 1–1.

It puts both teams scoring at 50% and over 2.5 goals at 44%.

A 66% selection is expected to miss in the remaining share of matches, and football regularly produces red cards, injuries and tactical changes the data cannot see. Treat this as a probability, not a forecast of the result.
