EASTERN'S A team served notice of their determination to retain the President's Cup seven-a-side title with a ruthless 7-0 victory over Kui Tan A in their first outing at Mongkok Stadium last night. Striker Paul Nixon was the star of the show, using the extra space to display his tricks and skills and cause havoc in the Kui Tan defence. On a pitch as true as it will play all season, Nixon helped himself to a hat-trick, including two in the first six minutes, and was joined on the scoresheet by skipper Lee Kin-wo, Lee Wai-man, Tam Siu-wai and Chiu Chun-ming. After today's rest day, Eastern A meet South China A in the quarter-finals tomorrow afternoon. The Caroliners, whose B team were humbled 1-0 by Kui Tan B on Thursday evening, moved goalkeeper Allen McKnight and playmaker Chiu Chung-man into the A side, tournament rules permitting players from a beaten side to join the club's surviving team. And midfielder Chiu showed his quality in the second minute, splitting the Rangers A defence with a delightful pass with the outside of his right foot into the path of right-winger Loh Wai-chi, who finished clinically. In the second half, Anto Grabo and Chiu combined to create a second goal for Loh, who scored with a close-range header. With the game safe, South China sent on Dutch winger Niels Gerestein and he quickly teed up left-back Chan Wai-chiu to complete the 3-0 victory. Sunday's quarter-final line-up is Instant-Dict A v Sing Tao A, Eastern A v South China A, Eastern B v Voicelink B and Instant-Dict B v Happy Valley B. In other second-round action last night, Sing Tao A beat Happy Valley A 1-0 with a Tam Ah-fook header two minutes from time but Sing Tao B lost out in a penalty shootout to Voicelink B. Instant-Dict B were given the cushion of a classy early goal from striker Graham Harvey and went on to beat Rangers B 3-0. Harvey added a second and set up Ian McParland for the third. Happy Valley B needed an injury time winner from Wong Fuk-wing to knock out Kui Tan B.
