Arsenal striker Park Chu-young scored the opener as South Korea defeated Switzerland 2-1 in the Olympic football tournament Sunday.
The 27-year-old put his side in front with a diving header in the 57th minute. Innocent Emeghara pulled one back for the Swiss in the 60th but Kim Bok-yung got the decisive goal for South Korea three minutes later.
The result left the South Koreans in second place in the group, behind leaders Mexico on goal difference.
Switzerland is in third position with one point, ahead of fourth-place Gabon on goal difference.
In Sunday’s earlier Group B game Mexico beat Gabon 2-0.
The final group games will be played Tuesday when Switzerland faces Mexico and South Korea plays Gabon.
