Slots in the AFC Champions League semi-finals will be decided on Wednesday with Japan's Urawa Reds and Korea's Seongnam Ilhwa Chunma well placed to make the last four.

Japanese champions Urawa and Korean titleists Seongnam hold 2-1 advantages from their quarter-final first legs as they visit Korea's Jeonbuk Motors and Syria's Al Karama respectively.

The matches between Japan's Kawasaki Frontale and Iran's Sepahan, and Al Hilal of Saudi Arabia and Al Wahda of the United Arab Emirates, are deadlocked after goalless stalemates last week.

Urawa are still kicking themselves after allowing defending champions Jeonbuk to scramble a crucial 90th minute away goal in the first leg, making their task that much harder on Wednesday.

It means Choi Kang-hee's Korean side need only a 1-0 win at Jeonju World Cup Stadium, a venue where they won five of six matches on their surprise run to the title last year.

If Jeonbuk win, they would play either K-League rivals Seongnam or Syrian champions Al Karama, the team they defeated in last year's final, in the last four.

Seongnam, the losing 2004 finalists, came from behind with second-half goals from Kim Min-ho and Choi Byung-kuk to win their first leg encounter.

It crucially gives them something to defend in Syria where Al Karama have won seven of nine AFC Champions League matches over the past two years.

Kawasaki Frontale have struggled of late and need to regroup after a shock 4-0 hammering by Kashiwa Reysol in the J-League on Sunday evening.

Frontale manager Takashi Sekizuka made a number of changes with Wednesday's Sepahan clash in mind, but it was a setback to their preparations.

In contrast, Sepahan are in form, with four wins and a draw in their opening five games in the Iranian league.

The winners of that match will face either Al Hilal or Al Wahda for a place in November's two-leg final.

The two Arab giants ground out a goalless draw in the first leg with Al Hilal taking home advantage into the do-or-die showdown on Wednesday.
