Kosmina: Ange Postecoglou era starts with a bang but there's still plenty of work to do for Socceroos Coach Ange Postecoglou applauds his Socceroos in the match against Costa Rica. Picture: Greg Wood. THE Socceroos' performance against Costa Rica last Tuesday was unsurprisingly but very typically Ange Postecoglou-esque ... good, consistent tempo, look to play at all times and move the ball quickly. There was lots of first time passes, helped on or bounced around the opposition into spaces searching for combinations with teammates moving quickly between direct opponents. And they played much higher up the pitch than they have recently, compressing space and making it easier to press the opposition. It generally worked well and put the Costa Ricans on the back foot. Not that they really looked like they came here to win. With all due respect they have qualified for Brazil and had nothing to play for ... and that's just how they played ... without a lot of purpose which probably helped the Socceroos. This was a game for both coaches to have a look at players. For Postecoglou in particular he wanted to look at attitudes and capabilities, physically, psychologically and tactically. To this end the game served it's purpose but Postecoglou's work has only just begun. With five months until preparations begin in earnest he has got to spend a lot of time travelling, watching games and researching players. And he has got some hard decisions to make. I said last week that there could be a fair sprinkling of locals in the final 23 plus spares that go to Brazil, players who weren't in camp last week but need to be considered. Of those that were there three who never saw game time - Olly Bozanic, Alex Wilkinson and Michael Zullo. The latter at least has the benefit of having spent time under Ange at the Roar and I do believe he's a good option at left back given the way Postecoglou likes to attack with fullbacks. There is a plethora of central defenders that could do a job, aside from Lucas Neill who, after much conjecture, retained the captaincy-for this game The coach, however, has given no one any guarantees. He has stated publicly he wants to restore some pride in the shirt and make it a privilege once again to wear it ... rather than any entitlement. So he will choose his squad accordingly. Postecoglou's main problem for me is to find someone apart from Tim Cahill or Josh Kennedy to snatch a winner or to score freely. Based on Tuesday night's performance, Matthew Leckie could be the one. While he still needs to work on his finishing and touch his raw pace and athleticism are a problem for defenders. Regular game time has long been overdue for the ex-Adelaide striker but I think he could flourish under Postecoglou's management. All in all it was a good night out for the Green and Gold and the new boss. It was a welcome change to see them play with some long lost passion and a smile on their faces.
