Under the hood

How the model sees this match — the drivers and, after full-time, how the prediction scored.

Why this prediction

ExplanationAI · grounded

The model leans toward a Sparta Rotterdam result here, shaped mainly by Attacking xG form (home) and Defensive xG form (home). The probabilities come from the model — the prose only narrates them.

The AI writes the prose. It never produces or adjusts a probability — those come only from the model.
