The Day-1 nightcap offers a clean captaincy duel — South Korea's all-action Son Heung-min against Czechia's penalty-box finisher Patrik Schick. In Fantakick's scoring the 1.5x armband rewards involvement, not just goals, which tilts a close call. The case for each, with the maths.
A Fantakick captain returns 1.5x on one player in one match, so the question is pure: who does the most in this game? Son Heung-min is the high-involvement pick. Even a quiet night gives you the appearance, dribble and key-pass points; a good one — say a goal, an assist, two dribbles and the full 90 — is 15 + 7.5 + 3 + 1.5 = 27, and 40.5 with the armband.
Patrik Schick is the purer number nine: fewer touches, but a higher share of them end in the net, and he is Czechia's penalty taker (a converted penalty is 12 in Fantakick, a missed one −9). If you think this is a tight, low-event game decided by a single moment, Schick is the efficient bet; if you think it opens up, Son's all-round game compounds faster.
Fantakick pays for involvement, not just finishing. That's the thumb on the scale toward Son.
