Ognenovski opened the scoring on 29 minutes, bundling the ball into the net after a goal-mouth scramble, before fellow defender Cho Byung-kuk made it 2-0 seven minutes after half-time with a close-range header.

Zobahan pulled a goal back in the 67th minute through Mohammadreza Khalatbari to set up a tense finish.

But all nerves dissipated for the home side when Kim Cheol-ho squeezed home a third to make it 3-1 and all but seal Seongnam's first title since 1995.

The win also sees Seongnam qualify for FIFA's Club World Cup where they'll face some the world's best club sides.

The victory was all the more sweet given Seongnam's embarrassing loss in the final back in 2004.

The K-League club led Al Ittihad 3-1 after the first away leg in 2004 before being humbled 5-0 at home to lose out on aggregate.
