Embarrassed South China officials were left scratching their heads wondering where it all went wrong after the Caroliners were dumped out of the Asian Cup-Winners' Cup in Shizuoka, Japan, last night following the club's worst drubbing in years. Needing only a draw to go through to the quarter-finals of the tournament, Hong Kong's best supported club were thrashed 6-0 by J-League side Shimizu S-Pulse. The match was in complete contrast to the first-leg, second-round encounter played almost three weeks ago when South China won 3-2 at the Hong Kong Stadium in a performance which earned them plaudits as Team of the Month in November by the Asian Football Confederation. The former Hong Kong league champions were a shadow of themselves as they suffered their first defeat of the season against a Japanese onslaught which fully capitalised on South China's Brazilian central defender Cristiano Cordeiro's sending-off in the 18th minute for an overly physical challenge. 'We played badly and after Cordeiro was sent off, they killed us. We weren't allowed to come back into the game. They didn't give us a chance. We were lost after Cordeiro was sent off,' said a bitterly disappointed South China coach Casemiro Mior. 'We will now move on and try to put this behind us. We will concentrate on the domestic campaign. We also have the Guangdong-Hong Kong Cup early next month so we have lots of others matches to look forward to.' South China have followed the same path as arch-rivals Happy Valley, who were knocked out at the same stage of the Asian Club Championship last month. Valley were thrashed 8-1 by Dalian Shide, who completed a 10-1 rout on aggregate having won the first-leg, second-round tie 2-0 at Mongkok Stadium. S-Pulse, who are coached by Yugoslav Babic Branko, were in red-hot form going into the match at the Nihondaira Stadium. Last Sunday, they thrashed fellow J-League side Sanfreece Hiroshima 4-0 to reach the quarter-finals of the domestic Emperor's Cup. Brazil-born Alessandro Santos, who used to play under the name Alex before getting Japanese citizenship last month, opened the scoring even before Cordeiro was sent off. Brazilian Baron was brought down in the area in the 16th minute and Santos duly converted the free-kick. Cordeiro's sending-off only made matters worse for South China as Kohei Hiramatsu hammered home the Japanese side's second goal in the 36th minute before Jumpei Takaki added a third two minutes later. And for good measure Baron headed home a Yoshikiyo Kuboyama cross in the 43rd minute for a 4-0 lead at the break. The thrashing didn't stop there and the hosts completed a miserable evening for South China by scoring twice again in the 55th and 61st minutes through Kuboyama and Takaki to complete an 8-3 aggregate win.
