Newly-crowned league champions Sun Hei are confident of completing a clean sweep of titles when they play familiar foes Happy Valley in the FA Cup final on Sunday. Having already won the Senior Shield and League Cup (both against Valley) and now pipping Valley to the league championship, they are in a strong position to complete a domestic quadruple. 'It will all depend on how our players have come out of this game and whether there are any new injuries,' Sun Hei coach Koo Luam Khen said. 'But we are confident of making a clean sweep.' Cameroonian striker Julius Akosah, who scored the only goal in Sun Hei's league-clinching win, believes his side are strong favourites to take out the FA Cup. 'We are very confident now. I will be ready and my team will be ready on Sunday. We can win all the trophies,' said the 23-year-old. Happy Valley have the more difficult task of lifting themselves for Sunday's final. 'We have many injuries and we need to pick ourselves up,' Happy Valley midfielder Cheung Sai-ho said. 'It's extremely hard, but somehow we have to.'
