SEOUL (Reuters) - South Korea were left with plenty to ponder ahead of this month's World Cup finals after Edin Visca scored a hat-trick to give Bosnia and Herzegovina a 3-1 victory in a friendly in Jeonju on Friday.

The Koreans had been hoping for a win in their final match on home soil before heading to Europe but lacked accuracy in attack and looked fragile with a three-man defence at the back.
