After Ange Postecoglou named no Socceroos skipper, who should take over the armband? Fox Football's Mark Bosnich gives his thoughts on the Mark Schwarzer retirement. Will Tim Cahill replace Lucas Neill as Socceroos' skipper? ANGE Postecoglou might put the team before individuals, but at some point, he will need to decide on a Socceroo to don the armband to lead the country at the World Cup. The new boss described the captaincy debate as "interesting." Lucas Neill, the country's leader since Mark Viduka left the squad after the 2006 World Cup, is no longer guaranteed his spot in the back-four in Postecoglou's clean slate, so the leadership debate has become a focal point in Socceroos discussions. The squad still has a sprinkling of the 2006 class, namely Tim Cahill and Mark Bresciano, but Postecoglou will want to select someone guaranteed to be in his first XI. Does he opt for a short term certainty, or pick someone who will be alongside him for the long-term journey? So, who will best embody what Postecoglou is all about? Here's some contenders. Who do you want to select? Vote in our poll at the bottom of the story, and have your say! Everything is up for grabs and nothing is guaranteed under Postecoglou, hence why Neill has lost the armband. The veteran faces a fight just to make the first XI, and it doesn't make a lot of sense for Postecoglou to strip him of the captaincy, only to return it later. Neill, now playing at Omiya Ardija in Japan, is fiercely determined to make it to Brazil, but as Postecoglou implements change, Neill's tenure looks like one of the casualties. Cahill arguably took the mantle from Harry Kewell as the pin-up boy for the green and gold and is an undoubted fans' favourite. He is the country's talisman, x-factor and big game player and rouses the side with his work on the field. Cahill would be a short-term fix, but as Postecoglou muses over his formation and structure, he'll first have to decide if Cahill fits into that game in, game out. The popular creative midfielder further endeared himself with his apology on Fox Sports' Shootout program after the France humiliation, and has always been highly respected. Whether Bresciano is up for the off-field, media and public responsibilities at this stage of his career is something to consider. Also, given he is in the twighlight of his career, will he feature each and every game in midfield and does he have the legs to be picked against every type and style opponent? The Socceroos have a Premier League captain in their midst, with Jedinak the fearless leader at Crystal Palace. Former Palace boss Ian Holloway made no secret of his admiration for Jedinak's work with the armband. But, Jedinak hasn't been able to cement a permanent spot in the Socceroos' line-up. The Palace man has a wonderful physical presence, defensive instinct and workrate across the field - but can Postecoglou mould him to suit the passing style we suspect he'll prefer? If he does, like he did with Leigh Broxham at Victory over the past 18 months, Jedinak has to be a huge shout for the role. Postecoglou promoted Milligan ahead of Adrian Leijer as Melbourne Victory captain this season. He rates the energetic midfielder so highly, could he do the same thing at national level? After being part of the national set-up since being the 2006 World Cup bolter, Milligan finally broke into the first XI during this qualifying campaign, ahead of fellow captaincy candidate Jedinak. Postecoglou knows what he's capable of, and Milligan's well respected passing attributes could see him become a surprise nominee for the captaincy role. Like so many of these contenders, there's no guarantees McKay will be in Postecoglou's first XI. But, he was the coach's skipper at Brisbane Roar when they won their maiden A-League Championship, and has played his best football under the new manager when deployed in central midfield. Although he's one of the lower profile members of the squad, he is well spoken and no one works harder on the field. Richard Bayliss wraps up all of Wednesday's Socceroos news, with Ange Postecoglou's Soceroos squad looking vastly different thanks to the retirement of veteran goalkeeper Mark Schwarzer.
