HONG KONG ended their Olympic soccer campaign on a note as dismal as the weather when they were thrashed 4-1 in a first-half destruction by Indonesia at rain-sodden Mongkok Stadium last night. Coach Raymond Ng Wai-man was hoping the territory would give it their all in their fourth and final Group C match but was aghast to see his charges 4-0 down by the 44th minute and finishing with just nine men after midfielders Lau Tik-lun and Lee Wai-man were sent off late in the second half after picking up their second yellow cards. Striker Kurniawan Yulianto was the hero for Indonesia, scoring a brace of goals including a superb 29th minute header which gave no chance to Hong Kong goalkeeper Kevin Lok Kar-win. Indonesia, who were beaten by group winners and Atlanta qualifiers South Korea in both legs (1-0 and 2-1) easily accounted for the territory who were still recovering from their 7-0 thrashing by South Korea in Seoul earlier this month. Hong Kong finished a disappointing campaign at the bottom of the standings, conceding 17 goals with just one goal scored. Indonesia were immediately on the rampage as they peppered Hong Kong's defence with surging runs and deep penetrative passes. After a half dozen clear chances went astray, Indonesia opened the scoring in the 28th minute through midfielder Indriyanto Setyo, who scored from the six-yard box. A minute later Yulianto, who had travelled with Italian giants Sampdoria on an exchange programme, scored the first of his two goals. He then made it 3-0 in the 33rd minute, beating Lok with a low shot from the top of the penalty area. Midfielder Ismayana Arsyad rubbed salt into the territory's wound with Indonesia's fourth in the 44th minute from an acute angle before Hong Kong striker Chan Chi-hong found the net after a rare foray into the Indonesian box.
