South Korea captain Son Heung-min will need time to re-adapt following his return from surgery to stabilise a fracture around his left eye, head coach Paulo Bento said after they held Uruguay to a 0-0 draw in their World Cup opener on November 24.
Son, playing in a black protective mask, spearheaded the South Korean attack but did not have much impact as they had six attempts at goal but none on target.
Bento said the 30-year-old, who was injured midway through Tottenham Hotspur's Champions League match at Olympique de Marseille this month, joined the squad only in recent days.
"Son is a player who, up until his, injury, had continuous rhythm and good performance," Bento said of Son, who had five goals and two assists for Spurs this season before the World Cup.
"He had a serious injury, he was inactive for a considerable time. He joined the team only in the last few days.
"After an injury and being exposed to more aggressive games, it is natural it will take him some step to re-adapt."
