Victory's Mark Milligan excited for new Socceroos era under Ange Postecoglou Mark Milligan and Matt McKay warm up at Socceroos training at Kogarah Oval. LIKE the first day of the new school year, Melbourne Victory and Socceroos midfielder Mark Milligan feels a sense of nervous excitement ahead of the first Australian team camp under new coach Ange Postecoglou. Most of the 22 players selected by Postecoglou for next Tuesday's friendly against Costa Rica will have arrived in Sydney by this afternoon. Milligan, 28, knows what to ­expect from his former Victory mentor after spending 18 months under his guidance, but is eager to find out what plans Postecoglou has in store for the national team. "There are definitely a few nerves, but it is exciting at the same time," he said on Sunday. It's rejuvenating. Change is always that way and I think we needed it. That's definitely not saying Holger (Osieck) should have got sacked or anything like that - just, after two poor results against Brazil and France, I think to lift morale it's been good in that sense. It's difficult to say (what changes Postecoglou is going to make), we'll find out once we get in to camp. I'm lucky enough that I know Ange, I know how passionate he is firstly as a coach and secondly about our country. It'll be very interesting. Being a double international date,Milligan said the Socceroos would benefit from spending time together in camp and said the game against 31st-ranked Costa Rica would be a good chance to see if the subtleties of Postecoglou's game plan had started to click. Milligan will miss Victory's away clash with Western Sydney Wanderers at Pirtek Stadium on Saturday night because of international duties. The match takes on added importance after the weekend's 3-2 loss to Sydney FC at Allianz Stadium. The Sky Blues took a 2-0 lead early on, were pegged back to 2-2 after an Archie Thompson strike and James Troisi's fifth goal of the season, but retook the lead prior to halftime through Alessandro Del Piero's penalty despite being ­reduced to 10 men just before Troisi's equaliser. In little more than 90 minutes of football - from the 37th minute against Wellington to the 36th against Sydney - Victory leaked five goals. But Milligan was pragmatic about his team's defence. Mark Milligan endured a frustrating Big Blue. "We look at the way we concede those goals as well," he said. There's always a reason and I think in many senses we were a little unlucky (on Saturday night). The first goal was a little bit of miscommunication, we just flicked the ball on to them. With the second goal there was absolutely nothing we could do about that. We've cleared a header and it's hit the boy in the face and gone in, so that's just something you have to deal with. Individual mistakes happen, but we look at it from a team sense and they didn't score because we had poor structure or anything like that.
