Double strikes from Leonardo and Lee Dong-gook catapulted Jeonbuk Hyundai Motors to a 5-0 victory over Sven-Goran Eriksson's Shanghai SIPG as it stormed into the AFC Champions League semifinals Tuesday. The 2006 champion was held for 52 minutes in the quarterfinal second leg in Jeonju before Leonardo's well-taken goal blew the floodgates open. Shi Ke's own goal doubled Jeonbuk's lead before Leonardo scored again from the spot and veteran striker Lee came on for a sublime cameo with goals in the 84th and 88th minutes. The emphatic result makes a statement for Korean football at a time when China's mega-rich clubs are hogging the Asian limelight and attracting a steady flow of top players. FC Seoul is also well-placed against Chinese opposition as it takes a 3-1 lead into the second leg of its quarterfinal against Shandong Luneng Wednesday. For SIPG's former England manager Eriksson, it was a night to forget as Brazilian new signing Hulk failed to make headway against the efficient Jeonbuk defense. Jeonbuk laid seige to the SIPG goal in the first half without creating much in the way of clear-cut chances, for all their dominance. Tall forward Kim Shin-wook, sporting a blond mohican, had the ball in the net in the sixth minute but it was chalked off for a foul on goalkeeper Yan Junling. And the busy Yan did brilliantly to deny Kim Bo-kyung on 25 minutes when he dived low to push his rasping shot around the post. Jeonbuk's relentless pressure finally told seven minutes into the second half but it took a well-worked move to finally break SIPG's resistance. Kim cushion-volleyed a lay-off to Leonardo on the edge of the box and the Brazilian made no mistake as he arrowed his shot past goalkeeper Yan. Wu Lei then had a great chance to level matters against the run of play, and he came to rue his tame shot when Jeonbuk grabbed its second on 58 minutes. Lee Jae-sung's cut-back was inviting but it was SIPG's Shi Ke who inadvertently bundled it into his own net as he rushed back to cover. Worse was to come when Lu Wenjun was sent off for kicking Kim Hyung-il in the head as he tried to clear off his own goal line. And SIPG's evening deteriorated still further when Jeonbuk added three more goals to its tally in a dizzying final eight minutes. Leonardo scored from the spot after substitute Lee Jong-ho was fouled in the box, before Lee Dong-gook, introduced on 63 minutes, twice finished sharply to round off a miserable night for Eriksson's team. In the day's other quarterfinal, 2003 champion Al-Ain sealed its second semifinal appearance in three seasons with a 1-0 win over Lokomotiv Tashkent. After a goalless first leg, Al-Ain's Caio Lucas Fernandes scored the only goal of the match seven minutes before the break with a strike from the center of the penalty area and the club survived a second-half Lokomotiv fightback. Al-Ain will face the winner of the quarterfinal clash between Al-Nasr and El Jaish.
