Dejan Damjanovic was the star, scoring one and creating the other two in a scoreline that was flattering to the hosts, who only sealed the points on the stroke of full time.

Seoul took the lead on the half-hour mark as Damjanovic headed home a Hyun Young-min corner from close range.

The Montenegrin international turned provider in injury time, rolling the ball across goal for Adilson to slot home from close range and there was still time for Ha Dae-sung to round the keeper after being freed by Damjanovic.

"It was a good win for us," said Seoul's Portuguese coach Nelo Vingada.

"We worked hard and deserved the victory.

"The score was 3-0 for us but anybody who saw the game with their own eyes knows that this was a very tough game."
