The 26-year-old South Korea star is in great form again this season and the ex-England striker has been impressed by his attitude and versatility
Tottenham star Heung-min Son is "flying" this season and any manager in the Premier League would be happy to have him in their team, Alan Smith says.
The 26-year-old is having another productive season with Mauricio Pochettino's side, scoring eight goals and supplying five assists in 17 Premier League appearances.
The South Korea captain had an instant impact when he teamed up with the national team during the Asian Cup this month, winning the penalty that saw them open the scoring before setting up another goal in a 2-0 win over China.
