At least one Korean club will reach the semifinals as Seongnam Ilhwa and a resurgent Suwon Bluewings face off in a clash between two winners of the former Asian Club Championship.

Seongnam hosts  the first of the two legs at the Tancheon Sports Complex south of Seoul, where the two Gyeonggi giants recently drew 0-0 in the K-League. Seongnam, Korea's most successful club with seven K-League titles, are currently third in the table after two draws earlier this month.

Since taking charge last season, former club captain Shin Tae-yong has moulded an impressive side led by the attacking talents of former Colombia international Mauricio Molina and Macedonian target man Dzenan Radoncic. Both have scored eight times in this year's K-League, while Molina has also scored four times in the AFC Champions League.

Australian center-back Sasa Ognenovski captains the team from central defence, while goalkeeper Jung Song-ryong established himself as Korea Republic's number one at the FIFA World Cup.

Suwon, who won their fourth K-League title in 2008, have regained their confidence since Yoon Sung-hyo took over from Cha Bum-kun in June, when the side was rooted to the bottom of the 15-team K-League.
 

Jeonbuk Motors, the 2006 AFC Champions League winners, will hope for an inspired performance against  Shabab when the reigning K-League champions host the Saudi giants at the Jeonju World Cup Stadium.

Jeonbuk's 3-1 home loss to Gangwon on Friday marked their third defeat in five K-League matches, while last month Choi Kang-hee's men were knocked out of the FA Cup by Suwon and beaten by FC Seoul in the K-League Cup final.

The Motors remain a strong attacking force. Brazilian winger Eninho is currently the league's joint top scorer with 13 goals, while strikers Lee Dong-gook and Croatian Kruno Lovrek have both netted eight times.

Shabab have had a slow start to the 2010-11 Saudi league under new coach Jorge Fossati, picking up just four points in four games. Following two losses, Saudi Arabia striker Nasser Al-Shamrani scored twice in the 2-1 home win over Al Ittifaq before missing a penalty in a goalless draw at Nasr.

Last month the 'White Lions' lifted their first trophy under the former Uruguay boss when they won the Elite International Championship friendly tournament in Abha.
 

Zobahan host holders Pohang Steelers at the Foolad Shahr Stadium in confident mood after enjoying a strong start to the 2010-11 Iran Pro League.

The Esfahan club, league runners-up in the last two seasons, are currently two points clear at the top after beating Tractor Sazi 2-1 on Friday. Goals from right-back Mohammad Hosseini and striker Mohammad Ghazi secured their sixth win in eight games.

Iran international Mohammad Khalatbari is the Greens' leading striker, while other current internationals include Hosseini, midfielder Ghasem Hadadifar and goalkeeper Shahab Gordan.

Pohang have gone off the boil after K-League losses to Jeonbuk and FC Seoul earlier this month ended a run of five unbeaten games under former assistant coach Park Chang-hyun, who took over from Waldemar Lemos ahead of the round of 16 in May.
 

Saudi champions Al-Hilal will look to make the most of home advantage at the King Fahd International Stadium in their star-studded clash with Qatari champions Al Gharafa, who are captained by former Brazil star Juninho.

Hilal has been outstanding under Belgian legend Eric Gerets, winning the 2009-10 Saudi league and Crown Prince Cup earlier this year and kicking off this season's campaign with four straight wins.

The Riyadh club — which recently announced that Sven-Goran Eriksson would take over from Gerets after he leaves to coach Morocco —maintained their winning formula by retaining all four of their foreign stars over the summer.

Sweden winger Christian Wilhelmsson and Romania midfielder Mirel Radoi, both recently involved in Euro 2012 qualifiers, Brazil Olympic star Thiago Neves and full-back Lee Young-pyo, fresh from his third World Cup, have all played a big part in Hilal's recent success.

Saudi Arabia striker Yasser Al -Qahtani has already scored four times in the league, with Hilal edging Ittihad on goal difference after four games.

Like Hilal, Gharafa have retained their four foreign stars from the group stage. Younus Mahmood, Iraq's AFC Asian Cup-winning captain, strike partner Clemerson of Brazil and Moroccan midfielder Otman El Assas are key players, although Juninho is arguably the tournament's most high-profile player.
