Moon gave the visitors the ideal start, finishing off a move that saw Anderson picked out on the left edge of the penalty area and the Brazilian steered the ball into the centre for the winger to score.

Twelve minutes later Anderson added the second, showing his individual qualities when he controlled Hrvoje Babec’s sweeping pass from the right on his chest before lashing a rising shot beyond Nguyen Van Viet and into the top corner.

Moon was the architect of FC Seoul’s third in the 29th minute, crossing from the right to Leonardo Ruiz at the far post and his header back across the face of goal was directed home as Hwang Do-yun scored with a diving header.

The onslaught continued in the 34th minute with Cho converting from another Moon centre, the ball finding the striker close to the penalty spot and he swept his first time shot into the corner. Cho almost hit a fifth for FC Seoul, thumping the woodwork in the 36th minute.

Anderson was involved again, feeding Babec as he burst into the area and the Croatian midfielder delivered for Leonardo to score on the turn from the edge of the six-yard box.

Al Arab was dismissed when he needlessly upended Van Khang on the edge of the FC Seoul penalty area to earn his second booking of the match but it mattered little as the visitors cruised to victory.
