Indispensable Son inspires Spurs

LONDON - Son Heung-min has every reason to be constantly smiling, and Tottenham Hotspur has many reasons to be thankful.

For a player so understated, so seemingly undemanding, the 26-year-old forward from Chuncheon, South Korea, has become indispensable for Spurs.

Borussia Dortmund was reminded of that in the Champions League on Wednesday night, when Son scored the opener to spark a 3-0 victory in the last-16 first leg.
