HONG Kong soccer minnows Kui Tan capitalised on their superior fitness to sink highly fancied Instant-Dict 2-0 in a First Division clash at Mongkok Stadium yesterday. Kui Tan, who finished second from the bottom last season, but were reinstated when Michelotti folded after running into financial difficulties, put up a spirited performance to earned the admiration and applause of the 1,511 crowd. ''It was a good start for us and this win should boost our morale. We'll be giving the team a $30,000 bonus and hope they can keep it up,'' said Kui Tan manager Raymond Ng Wai-man. Instant-Dict, with a budget of $6 million - exactly double that of Kui Tan - were strongly fancied to start their season with a victory, but they rarely came even close to scoring. Despite the disappointing performance, club president Thomas Tam Wai-chuen said: ''This was our first match of the season and the players looked in need of a bit of time to build their teamwork. But I think we should be okay once we've settled down.'' Kui Tan, who were on the defensive virtually throughout the opening period, shocked their rivals one minute into the second half when they took advantage of a blunder by Instant-Dict goalkeeper Chan Sau-yin to take the lead. Chan fumbled when trying to catch the ball from Billy Bone's corner-kick. John Bottomley was on hand to crash home the loose ball from close range. Instant-Dict pushed flat out for the equaliser and had their chances, but Kui Tan's Yam Wai-hung, was in immaculate form, twice denying Harvey with remarkable saves. Kui Tan sealed the game in the 78th minute, after Bone floated a long free-kick into the Instant-Dict area. Goalkeeper Chan and the incoming Derek Hunter collided and the ball bounced loose to Richard Crossley, who tapped home to make it 2-0. Chan had to be taken off on a stretcher, with a nasty cut on his face.
