Paraguayan super fan Larissa Riquelme may have been absent, but the country's on-field poster boy Roque Santa Cruz more than made up for the model's decision to stay at home by inspiring his national team to a comprehensive 7-0 hammering of Hong Kong last night. The Manchester City striker has been having troubles of his own this season at Eastlands, where he has barely featured for Roberto Mancini's team, but the 29-year-old showed he lacks little when it comes to having an eye for goal. Santa Cruz scored twice and set up two more for second-half substitute Jose Ortigoza as Gerardo Martino's side handed Hong Kong a football lesson just days after the territory's run to the second round at the Asian Games in Guangzhou. Four of the players who represented Hong Kong at the Asiad were included in Tsang Wai-chung's squad for the game at Hong Kong Stadium against the World Cup quarter-finalists, yet only Lee Chi-ho and Lo Kwan-yee made it into the starting line-up. Despite the defeat Tsang was trying to take the positives from a performance in front of a paltry crowd of 6,250 who witnessed the sheer gulf in class between Hong Kong and one of South America's leading nations. 'The score is not so good and we're disappointed about the result,' said the Hong Kong coach. 'But from a technical point of view we will have learned from this game. 'They are a different class of opponent, they are so professional. They came a long way to play here and they showed how good they are. 'They are preparing for the Copa America and called up most of their players who play overseas because they were taking this game seriously. They tried their best and they showed how good they are in attack and defence. 'They scored seven goals but they were also very good in defence and it is this defending ability that we want to look at and learn from because if you never play against this kind of opposition you will never learn.' Hong Kong had the worst possible start when, with less than five minutes on the clock, Santa Cruz opened the scoring with an unopposed header past Zhang Chunfui following a pinpoint cross from Nestor Camacho. Camacho did more damage 26 minutes later when his run and cross down the left evaded Santa Cruz, only for Zhang to parry the ball into the path of Edgar Barreto, who hit the back of the net with aplomb. An appalling mistake by Zhang - the goalkeeper mis-kicked the ball directly at Santa Cruz - allowed Paraguay to add a third in the 33rd minute as the City forward made sure from close range. The half-time introduction of Ortigoza ignited the Paraguayan attack further and within 10 minutes of the restart Santa Cruz had set up two goals for the 23-year-old. The first saw Santa Cruz slide a perfectly weighted ball into Ortigoza's path before he tucked the ball beyond the reach of replacement goalkeeper Tse Tak-him in the 47th minute while eight minutes later Hernan Perez's run and pass found Santa Cruz, who in turn set up Ortigoza with an easy finish into an unguarded net. Paraguay never eased off the gas despite the difference between the sides and two more goals came in the final 16 minutes with Marcos Riveros netting with a half-volley before Cristian Riveros headed home Aureliano Torres' injury-time free kick. 'We think we did a good job and we were able to score quickly and we were able to play without stress,' said Martino. 'We did what we needed to do according to our opponent's level so I'm happy with the result. 'We already knew the difference between both teams but in football you have to show those differences on the field, even if you are good you have to do it on the field. 'It's not easy to score seven goals so the result has the meaning that it has.'
