Brazilian striker Detinho celebrated his 37th birthday in style last night by scoring once and setting up another goal during Citizen's 3-1 victory over Tai Chung at Siu Sai Wan Sports Ground. Detinho had a hand in teammate Helio Goncalves' opening goal in the 11th minute before scoring a minute later. Sham Kwok-keung added the third in the 56th minute. Tai Chung's Muenyi Lukalu Muana scored his team's consolation. Citizen moved to fifth spot. TSW Pegasus, who thrashed HKFC 5-1 on Friday, are top. The day's other match between Tuen Mun and Kitchee was postponed due to a waterlogged pitch at Tuen Mun Sports Ground.
