Edin Visca scored a hat-trick as Bosnia and Herzegovina condemned South Korea to a 3-1 friendly defeat in a major setback to their World Cup preparations on Friday.

Tottenham Hotspur forward Son Heung-min was unable to make an impact as Visca scored in the 28th minute, just before half-time and then in the 79th to steal the show in Jeonju.

It made for a low-key send-off for Shin Tae-yong's South Korea, who were playing their final home warm-up and will face holders Germany, Mexico and Sweden in a tough Group F in Russia.

After Visca opened the scoring, midfielder Lee Jae-Sung levelled for the hosts two minutes later, only for the Bosnian midfielder to grab his second just moments before half-time.

And Visca, who plays for Istanbul Basaksehir in Turkey, dashed any hopes of a late South Korean comeback when he completed his treble in the 79th minute.

The teams traded chances early on. Roma striker Edin Dzeko fired just over the bar in the 12th minute, and fluffed a one-on-one opportunity nine minutes later.

Son went close for South Korea in the 27th minute, when he danced past two defenders but was denied by goalkeeper Ibrahim Sehic at point-blank range.

One minute later, Eldar Civic's cross failed to find Dzeko, but it deflected off defender Kim Min-woo and found Visca's foot to make it 1-0 to Bosnia.

The home team bounced back near the half-hour mark as Lee, fed by Hwang Hee-chan, flicked over Sehic.

But in first-half injury time, Haris Duljevic caught the South Korean defence napping with a long cross for Visca, who easily beat goalkeeper Kim Seung-Gyu for a 2-1 lead.

South Korea exerted pressure in the second half but were wasteful in attack -- and they were made to pay when Visca struck 11 minutes from time.
