HONGKONG must be ready to repel an early onslaught from South Korea when the second phase of the Asia Group D qualifying tournament for the 1994 World Cup kicks off today at the Olympic Stadium. For the Koreans' head coach, Kim Ho, said his side would be going for a quick kill to put them in total control of the group before their matches against Lebanon, India and Bahrain. After the first phase in Beirut, Lebanon, South Korea lead with seven points from three wins and a draw. Hongkong are second on five points from two wins and a draw. The group winners join the winners of the other five groups in a final six-team Asian qualifying tournament, from which the leading two go through to the World Cup finals in the United States. And Korean coach Kim can virtually book a place alongside the other five group winners if they can overcome Hongkong for a second time after beating them 3-0 in Lebanon. ''We will be going all out to get a goal as quickly as possible and then control the match,'' said Kim. ''We made a bad start in Lebanon by drawing 0-0 with Bahrain. ''This time we are much better prepared and our play will be more refined.'' Kim delayed naming his side until today, giving more time for a couple of players to shake off minor injuries. These include striker Hwangbo Kwan, one of only four survivors from their Italia '90 World Cup squad. He is best remembered for scoring a thundering free-kick against Spain, who won 3-1. Kim added: ''Hongkong's strongest point is their speed from defence to attack and their most impressive player is the little number eight, who is very good at distributing the ball.'' The little number eight, Eastern midfielder Tam Siu-wai, and his teammates trained at the Olympic Stadium yesterday. And the giant electronic scoreboard greeted the Hongkong players by showing a scoreline of South Korea 1 Hongkong 0. The groundstaff said they were just testing the equipment, no offence meant. Korea, yet to concede a goal in the competition, will take on a Hongkong side with only one striker in Lee Kin-wo, supported by Loh Wai-chi on the right, Tam through the middle and, on the left, Au Wai-lun. Cheung Kam-wa will play in the centre of midfield. Hongkong coach Chan Hung-ping said his players had found it difficult to handle the pace and the aggression of the Koreans in their first meeting in Beirut but knew what to expect this time. ''In Hongkong you get a lot of time on the ball but the Koreans always chased back so quickly. As a result we were unable to play with any pattern and completely lost our confidence,'' said Chan. ''But if we are going to reach the next stage we have to beat them ourselves and not rely on them dropping points to the other teams. ''It is most important the we make the most of every chance we create. ''South Korea are one of the strongest countries in Asia and it will be a big honour for Hongkong if we can beat them,'' he added. Hongkong (probable): Chung Ho-yin; Chiu Chun-ming; Lo Kai-wah, Yan Lik-kin, Chan Chi-keung, Lee Wai-man; Loh Wai-chi, Cheung Kam-wa, Tam Siu-wai, Au Wai-lun; Lee Kin-wo (captain).
