With two new Brazilian signings and six weeks of pre-season training already under their belts, Happy Valley are aiming to cause an upset in the first game of the season by beating champions Xiangxue Sun Hei tomorrow. The defending champions and last season's runners-up will face off in the opening match of the 2005/2006 season at Hong Kong Stadium. Sun Hei were dominant last season, sweeping all four domestic competitions. But Happy Valley team manager Michael Shek doesn't expect them to have it so easy this time. 'When you reach the top, it is very hard to stay there,' said Shek at a season-launch event on Wednesday. 'They were at their best for six solid months last season. It will be tough for them to maintain that kind of form. Last season was Sun Hei's best-ever season.' Valley have looked good during pre-season training, losing just one out of their eight warm-up matches. The team also spent several weeks at a training camp in Guangdong. 'We are well prepared - better than ever before. We've signed two quality players. I think we will do better this season,' Shek said. The new Brazilians, Evan Or, a midfielder, and Marcel, a centre-forward, will join their countryman, Jose Ricardo Rambo, at Valley. Sun Hei, with a new sponsor this season - Xiangxue - are aiming for a repeat sweep. 'Our target is to win all four titles again,' said their manager, Chung Chi-kwong. 'No one thought it was possible last season but we did it. It could be tougher this season. Opponents will change their tactics and raise their game because we are champions.' The champions signed young midfielder Chan Yu-lun from Kitchee during the summer, and expect to have a Brazilian striker on their books soon. 'Chan is a very good shooter, skilful, and good with free kicks and corners. He will be a valuable addition. We will announce the other signing next week,' Chung said. He expects a big turnout. 'We hope 3,000 will come. It's the first game, and the best teams are playing,' Chung added. Each spectator will receive a programme souvenir, while all the tickets will be entered for a lucky draw offering 500 gifts. The proceeds from this match will go to the Yan Chai Hospital charity. Kick-off is at 3pm. Tickets cost $20 and $60.
