South Korea's Son opts for substance over style

SEOUL - Son Heung-min sported a shock of dyed yellow hair at the last World Cup in Brazil to stand out from the crowd.

Four years later in Russia, the South Korean forward is opting for substance over style as he bids to live up to lofty expectations.

Son, then with German club Bayer Leverkusen, was one of the few players who left the 2014 tournament in Brazil with any credibility after South Korea's train wreck of a campaign ended in the group stage.
