Sun Hei defender Jose Ricardo Rambo scored the solitary goal in last night's Hong Kong First Division match against Sai Kung - but it made all the difference. Needing a win to qualify for a top-four place in the championship phase, the Brazilian headed home a Leslie Santos cross in the 12th minute to set up a crucial victory at Mongkok Stadium. Sun Hei coach Cheung Chi-tak breathed a huge sigh of relief after the final whistle as his men collected three precious points to move them to third in the table. 'It was nerve-wracking to the very last minute. We were pinned back in defence after scoring that early goal. We lasted until the very end,' said Cheung. 'We needed to win tonight. Had we lost, we would have been fighting to avoid the big drop in the relegation playoffs. I'm totally relieved that we won,' he said. Sai Kung forward Leandro Simioni probably had the best chance of equalising in the 86th minute but Sun Hei goalkeeper Ho Kwok-chuen kept out the Brazilian's 30-yard effort. Cheung said: 'It was struck really well but luckily Kwok-chuen was at the right time and place. 'It looked to be heading towards the top right corner of the net but Kwok-chuen is an experienced goalkeeper and somehow he palmed it away.' Earlier, Instant-Dict beat Kitchee 2-1, but the one-time Hong Kong champions had already been condemned to another season fighting to avoid relegation. Instant-Dict moved up a place to sixth spot on 17 points. The Dickies will play in the relegation playoffs for the second successive season despite goals from Anto Grabo and Rochi Putiray. Anilton Conceicao scored the consolation goal for Kitchee, who are now second from bottom.
