Heung-Min Son has revealed that heartache at the Olympic Games has triggered his recent form.

The Tottenham attacker has made a great start to the new season, scoring five goals in as many appearances.

Son, 24, crashed out of the quarter-finals with South Korea against Honduras at the Olympics.

The winger has revealed that he has been driven to succeed following the failure in the summer with his national team.

“It was true after the (Olympic) Games I was very upset. I was really down because I play for my country and want to get some medals for my country,” he told The Sun. “My heart was already in it for six months beforehand, I was there, but after Olympics I thought now I have to focus on the season.

“It was not easy but everyone, my family, my teammates, help me a lot and made me stronger than before. It is true I am in great form and have made a great start but I have to keep working hard so I can keep finishing like this.”

Son scored the winning goal on Tuesday night against CSKA Moscow in the Champions League.

He also grabbed the decisive goals in a 2-1 win against Middlesbreough on Saturday and has become a crucial player for Mauricio Pochettino in recent weeks.

Son struggled in his first season with the club last year and made 40 appearances for Spurs, with 18 of them coming as a substitute.

The former Bayer Leverkusen ace impressed during his time in Germany and netted 29 goals in just 87 appearances.
