Al Hilal lifted the AFC Champions League trophy for a record fourth time as Nasser Al-Dawsari's memorable first-minute strike set them on the way to a 2-0 win over Pohang Steelers.

At the King Fahd Stadium in Riyadh, Saudi Arabia, left-back Al-Dawsari produced a spectacular opener, and a clinical finish after the break from Moussa Marega tied up the triumph.

The breakthrough came inside 17 seconds with a remarkable long-range strike from Al-Dawsari, who snatched the ball in midfield and drove forward before lashing into the top-left corner from 28 yards with his left boot.

There was almost an equally dazzling reply from Sin Jin-ho in the 12th minute when he rattled the bar from the edge of the penalty area, the fingertips of goalkeeper Abdullah Al-Mayoof preventing the ball dipping in.

The ball fell to Lim Sang-hyub, but again Al-Mayoof made the save, scrambling to block the close-range shot.

Matheus Pereira thrashed a free-kick over the bar as Al Hilal looked for a second goal, while Pohang's Go Young-joon sent a shot skidding wide at the other end.

It was Marega who made sure in the 63rd minute, taking a throughball from Bafetimbi Gomis in his stride and firing low across goal into the left corner.

Victory means Al Hilal are now the outright most successful team in competition history, edging ahead of Tuesday's opponents who came into the game also with three previous titles.

Pohang Steelers came from behind to book their AFC Champions League final spot with a 5-4 penalty shootout victory over 10-man Ulsan Hyundai after a 1-1 draw.

Alex Grant nodded in a late equaliser before Pohang scored each of their five penalties, with Davy Bulthuis missing for Ulsan.

A cagey first half saw just two clear-cut chances, with Lee Seung-mo heading against the left post in the sixth minute for Pohang before Ulsan should have gone ahead on the stroke of half-time as Yun Il-lok headed a free-kick wastefully wide after being found unmarked at the back post.

The deadlock was broken seven minutes after the restart when Yoon Bit-garam's low ball across the face of goal was spilled by Jun Lee, allowing Yun to pounce on the loose ball and fire in from close range.

Pohang threw men forward in search of an equaliser but were nearly caught out as Yoon struck the right post from Lee Dong-gyeong's cutback, with Lee Jun rooted to the spot.

Ulsan were reduced to 10 men as captain Won Du-jae slid in on Lim Sang-hyub with his studs showing, earning himself a straight red card with over 20 minutes of normal time still to play.

The Ulsan midfielder's error of judgement proved costly as Pohang's man advantage paid dividends, with defender Grant heading in off the post in the top-right corner to level the scores with one minute of normal time remaining, forcing extra-time and then spot-kicks.

Ulsan centre-back Bulhuis was the only player to miss from the spot, blazing over the bar, although Lee Chung-Yong saw a tame stutter-stop effort easily saved, but was allowed to re-take it as Jun Lee was off his line.

Pohang scored all five spot-kicks, with captain Kang Sang-woo rifling the final penalty inside the left-hand post to spark wild celebrations.

The K League 1 side will face Saudi Arabian outfit Al Hilal in the final on November 23.
