I assume you mean in a final. In earlier rounds your only predicting final score, or final score + half-time score. Loads have people have got full marks for that at various times.
No-one's got it in the final though. In fact, Badger wasn't as close as I thought, because there's a bonus 2 points if your scorer is the first to score. Therefore the maximum points available on yesterday's game was 12 (not 10): 3 for half-time score, 3 for full-time score, 3 for exact time of first goal, 1 point for picking any of the scorers (as no-one scored more than once - it's 1 point per goal in this round) and 2 bonus points if your scorer scored the first goal (i.e. Van Bronckhorst).
The perfect Kibble will vary, depending on whether someone scores more than one goal, and if so whether one of their goals was the first.
The closest anyone has come is Sowton in 2002, who got 9 points off the Germany/S. Korea semi-final:
