Son Heung-min told South Korean soccer officials not to rush their search for a permanent coach as Jurgen Klinsmann lashed out over his sacking in February.

Tottenham star Son scored twice as South Korea booked its place in the final round of World Cup qualifying with a 7-0 thrashing away at Singapore on Thursday.

The Koreans were playing under their second interim coach since Klinsmann was fired following the team's semifinal exit at the Asian Cup earlier this year in Qatar.
