The attacker needed just a couple of minutes to hit the back of net.
Son Heung Min celebrates scoring the first goal for Tottenham Hotspur
It may have passed many by but the Olympics in Brazil has in fact already got underway.
The football tournament is already in full swing with eight group matches already completed.

The most eye-catching result of the day certainly belonged to South Korea. They thrashed Fiji 8-0 in Bahia.
A hat-trick for Bayer Leverkusen forward Seung-Woo Ryu and a brace apiece from Suwon Bluewings winger Chang-Hoon Kwon and Porto striker Hyun-Jun Suk tallied to seven. But Tottenham Hotspur’s very own Heung-min Son also got in on the act.
The attacker came on in the 70th minute against Fiji with the scoreline 4-0. Two minutes later he stroked home a penalty to make it five and open his account for the Olympics.
Many a South Korea and Tottenham fan was probably wondering why he did not start the fixture, but with Fiji the whipping boys of their respective group on is likely being rested.

It was a tough first season for Son at Tottenham Hotspur and this summer he has been linked with a move away from White Hart Lane.
Hopefully he can find some more goals in Brazil and come back to Spurs high on confidence ahead of a busy 2016-17 campaign…

I think Son was being eased into the tournament since Fiji is the easy opponent of the 3. Korea looked really good. Worked that goal diff— Matt (@OsideHotspur) August 5, 2016
