New South Korea coach Jurgen Klinsmann has promised to get Tottenham forward Son Heung-min firing and smiling again, as he noted that he felt for him at the last World Cup.

The former Tottenham forward, now coach of South Korea, said he has taken a keen interest in Son's faltering form for club and country.

The 58-year-old made this known during a press conference in Seoul, revealed that as a former Tottenham player, he watches almost all the games from Tottenham, and came to a submission that Son would be a necessary part of his plans for South Korea.

He said: "As a former Tottenham player I watch almost all the games from Tottenham and so I am a big fan of Sonny, there's no doubt.

"But I think this is a normal period that every player goes through, little ups and downs.

"I can give him encouragement and the motivation to enjoy himself and whatever role he plays on the field," Klinsmann added.

Son won last season's Premier League Golden Boot but then struggled through the Qatar World Cup with a facial fracture and has been far from his best this term at Tottenham.

Meanwhile, Klinsmann will see the 30-year-old Son when he takes charge of South Korea for the first time with a home friendly against Colombia on March 24.

South Korea reached the last 16 at the Qatar World Cup before being thrashed 4-1 by Brazil, but Son never got going at the tournament and wore a face mask to protect his eye socket.

He took charge of his native Germany in 2004 and led them to third place in the 2006 World Cup on home soil, losing to eventual winners Italy in the semi-finals.

His last coaching job was a 10-week stint in charge of Hertha Berlin in the Bundesliga more than three years ago.

Klinsmann, who signed a three-and-a-half year contract with the Korea Football Association, wants to win the Asian Cup early next year.

"We are only 10 months away from the Asian Cup in Qatar so I need to learn quickly," he said.

"He had a very difficult World Cup because he wasn't 100 percent healthy," said Klinsmann.
