South China stormed into the quarter-finals of the AFC Cup after scoring a convincing 4-0 win over Home United of Singapore at Hong Kong Stadium last night. A two-goal blast by Kwok Kin-pong and Li Haiqiang within two minutes in the first half gave the home side a comfortable lead, while Brazilian striker Caca and Li wrapped the match up with two more goals in the second period. 'We should have won by a bigger margin but we missed quite a number of chances in the second half. The result was still very encouraging,' said South China convener Steven Lo Kit-sing. 'The AFC Cup is our biggest target as I started preparing it after we lost in the group stage last season. 'Now I have to prepare the knock-out stage.' Lo said they would secure three new top quality overseas players in order to strengthen their hopes in the next stage, with some of the existing expatriates to be released. One of the foreign players who will not come back next season is forward Caca. The Brazilian, who joined South China in January and was believed to be the highest paid player in Hong Kong, said he had played his last match with South China. 'I will go back to Brazil as my wife is set to deliver my new baby next week, and I won't come back to Hong Kong,' said Caca, who has scored seven goals for South China in the AFC Cup. While Caca's departure is certain, South China have approached Hong Kong international Ng Wai-chiu, currently the only Hong Kong player starring in the China Super League with Zhejiang Lucheng. South China coach Kim Pan-gon said it was the best performance he has witnessed since he joined the Caroliners. 'We did not play for three weeks but the boys overcame the situation. It was a great night,' said the coach. 'Our target now is to reach the final of the cup. 'We will now do our best to challenge for the trophy and win it for Hong Kong.' The quarter-final draw will be conducted by the Asian Football Confederation on June 29.
