Central Coast Mariners coach Graham Arnold puts hand up for vacant Socceroos post A full wrap of Socceroos coach Holger Osieck's sacking, effective immediately. SOCCEROOS coaching candidate Graham Arnold says he'd love to oversee a dramatic culture change to fix Australia's wobbling World Cup campaign. Arnold and Ange Postecoglou are leading local candidates to coach Australia after Holger Osieck's sacking in the wake of a 6-0 loss to France in Paris on Saturday (AEDT). Foreigners Marcelo Bielsa, Gerard Houllier, Guus Hiddink and Frank Rijkaard are also potential replacements. Football Federation Australia (FFA) chairman Frank Lowy has hinted Australia needs a long-term outlook in its hunt for the next coach. Graham Arnold patrols the sideline as coach of the Mariners. Lowy said Osieck's sacking was based on "longer term issues of the rejuvenation of the Socceroos team," which has qualified for next year's World Cup in Brazil. Arnold, who has been an assistant under three Socceroos coaches - Frank Farina, Hiddink and Pim Verbeek - said he would love to coach Australia. "I'm a proud Australian and, if I was offered the job, of course I'd love to coach the Socceroos," he told Fairfax Media on Saturday. So if they want to come to me with an offer, yes, I'd have to consider it. Arnold maintained there was time for Australia to fix its World Cup preparations, which also included a 6-0 drubbing by Brazil before the heavy France loss. But we have to fix the culture. The culture is the first thing that needs fixing," he said. The players are better than what they are showing at this moment. Arnold, 50, said he would have to step down from A-League outfit Central Coast Mariners to coach the national team. Melbourne Victory mentor Postecoglou would also likely relinquish his A-League duties if given the Australian job. Matt Russell looks at the fallout from another 6-0 thrashing for the Socceroos and the subsequent sacking of coach Holger Osieck. Postecoglou will indicate his stance after Victory host Melbourne Heart on Saturday night. Arnold was emphatic that the national job was too big to combine with an A-League campaign. "I have had the experience of being there at two World Cups and I don't think people realise how massive the preparation for that really is," he said. You can't have someone doing two jobs. Nowhere else in the world does any nation ... have someone doing both a club and national team job. Ex-Argentina and Chile coach Bielsa lost his job as coach of Spanish club Athletic Bilbao in June and has stated he's open for offers. Frenchman Houllier watched the Socceroos get thumped in Paris and the former Liverpool boss was the subject of Australian approaches in 2006, when Guus Hiddink's tenure ended. Hiddink, who took the Socceroos to the World Cup round of 16 in 2006, is understood to still have strong support within the FFA, while Dutchman Rijkaard is also a potential candidate.
