IPOH  - Olympic hockey contenders are struggling to find that elusive winning formula at the Sultan Azlan Shah Cup, their last chance to tune up ahead of the London Games. Other than unbeaten New Zealand, the six London-bound sides in the annual Malaysian tournament have been inconsistent at best, but coaches expressed confidence that they can work out the kinks and find their best line-ups.Britain, India, Pakistan, South Korea, New Zealand and Argentina have all qualified for the Olympic hockey competition, which begins in July, while hosts Malaysia have not. But the play of the Olympic hopefuls has been a litany of missed chances, botched penalty corners and failure to execute game plans as they have sought to accustom themselves to the blue surface that will be also be used in London.“It is about learning to win matches and playing what you have been taught,” said India’s Australian coach Michael Nobbs. Nobbs had ripped into his team last week after they were crushed by 5-1 by the Kiwis on opening day last week, calling his defence “awful”.  The Indians are now joint second in the standings here along with Argentina, both having earned six points in four matches.“It is important that we put in practice what we have learned in training. Otherwise we face an uphill task against the bigger teams. In the Olympics you do not have the luxury of experimenting,” he said. India are making a return to the Olympics after missing the Beijing Games in 2008, and Nobbs is targeting a top-six showing.“We have not been playing to our ability in the four matches thus far and our form has been patchy to say the least,” he said. Asian champions Pakistan also have been unpredictable in their matches, which included a 4-0 defeat at the hands of South Korea on Monday that triggered calls for the return of players such as Shakeel Abbasi and Rehan Butt.The pair were not selected for London as they are currently the subject of a disciplinary inquiry by the Pakistan Hockey Federation after playing in the World Series in India earlier this year. Pakistan coach Khawaja Muhammad Junaid said the results in the Malaysian city of Ipoh should not be used to predict Olympic chances, adding there was time to iron out the team’s problems.“We are experimenting, and when this happens at times the results become the topic of debate. Let us not look too much into the results but rather the performances of the players here,” he said. “Why go back in time when we need to look forward. I believe that we are heading in the right direction.” Jason Lee, the coach of Britain, the highest-ranked team in the field in Malaysia at world number four, also said teams should not be judged too harshly. “We are also using (Malaysia) to select our bat players and test our combinations. Thus the form will be affected depending on whom we play. I believe that this is a good testing ground for all six teams,” he said.Britain is now joint third in the tournament with four points from three matches. No games were scheduled on Tuesday. Three more days of preliminary-round play remain before the finals on Sunday.
