Who's who in the new Socceroos Shane Brady examines the key stats for Ange Postecoglou's new-look Socceroos squad to face Costa Rica on Tuesday night. See how the new and old have been performing at club level. Goalkeepers Mitch Langerak Age: 25. Club: Borussia Dortmund, Germany Form: Started 2 games in league and Champions League this season. 0 clean sheets Socceroos caps: 2 Comment: Made 7 saves against France, several top-drawer. Game time limited but talent obvious. Age might edge him over Ryan. Mat Ryan 21, Club Brugge, Belgium Starts 18, 7 clean sheets in league, cup and Europa League Caps 3 If you're good enough, you're old enough. Hard to split him and Langerak. 35, Omiya Ardija, Japan 5 starts, 1 red card, 1 clean sheet Caps 95 (1 goal) The veteran lacks pace and game time but not experience. Ryan McGowan 24, Shandong Luneng, China Starts 29*, 1 goal, 10 clean sheets Caps 7 Solid defence helped Shandong finish second and qualify for the ACL. Jason Davidson 22, Heracles, Netherlands Starts 5, league and cup, 1 goal, 2 clean sheets Versatile left-footer who can play centre-back, left back or stopper. 26, Brisbane Roar Starts 5, 1 goal, 3 assists, 3 clean sheets Caps 5 Attacking fullback in hot form who can play either side. Rhys Williams 25, Middlesbrough, England Starts 12, 2 clean sheets, 1 assist, 1 red card Caps 13 Boro struggling in the Championship with just 3 wins and leaky defence. Alex Wilkinson 29, Jeonbuk Motors, South Korea Starts 26 in league, cup and ACL, 2 goals, 9 clean sheets Uncapped Running third in K-League and lost Korean Cup final on penalties. Michael Zullo 25, Adelaide United Starts 5, 1 assist, 0 clean sheets Caps 10 Fullback/winger on loan from Dutch club FC Utrecht. Has lost some zip from his eye-catching early days at the Roar. 29, Crystal Palace, England 11 starts, 1 clean sheet Caps 41 (3 goals) Standout in struggling EPL side. Aerial threat, tigerish in defence, but ball control and distribution could be better. Potential future captain. Mark Bresciano 34, Al Gharafa, Qatar 7 starts Caps 72 (13 goals) Class act but match fitness a concern. FIFA ban couldn't have come at a worse time for him or Australia. James Holland 24, Austria Vienna, Austria Starts 22, 1 red card Caps 12 Playing Champions League after league-cup double last season. Discipline a concern with 6 yellows to go with that red. Oliver Bozanic 24, FC Luzern, Switzerland Starts 15, 6 goals Caps 1 Goal-scoring midfielder got off to flyer in the Swiss league with back-to-back doubles. Tom Rogic 20, Celtic, Scotland Starts 2, league and cup Huge potential but might need a loan deal to be a serious contender for Brazil. Tommy Oar 21, Utrecht, Netherlands Starts 12 Caps 11 Pacy left-footed winger loves to take players on. Game time has been limited by injury issues. 30, Brisbane Roar Starts 4, 2 assists Caps 44 (1 goal) Back home after stints in Asia following disintegration of Rangers. Badly exposed against France and Brazil but improving. Mark Milligan 28, Melbourne Victory Starts 4, 1 clean sheet Caps 25 (2 goals) Reliable stopper has had almost as many caps as league starts this year. Could partner Jedinak in a two-man defensive screen. Dario Vidosic 26, FC Sion, Switzerland Starts 9, 4 goals Caps 19 (2 goals) Another goal-scoring midfielder flourishing in the Swiss Super League, just behind rival Bozanic on the scoring charts. 33, New York, USA Starts 29, 12 goals, 5 assists Caps 65 (28 goals) Back to his goal-scoring best in the MLS, and a favourite for the armband with Bresciano in limbo. Josh Kennedy 31, Nagoya Grampus, Japan Starts 24, 12 goals Caps 32 (17 goals) Target man with good feet averaging a goal every other game. Can't ask for much more in a striker. Robbie Kruse 25, Bayer Leverkusen, Germany Starts 3, 2 goals, 2 assists Caps 27 (3 goals) Used as an impact player at Leverkusen. Getting precious Champions League minutes, with more to come. Mathew Leckie 22, Frankfurt, Germany Starts 15, 7 goals Caps 4 (1 goal) Banging in goals in the Bundesliga second division. Powerful striker with big potential but might have to wait for his chance on the big stage. Full 2013 season stats for players in Asian leagues, others 2013-14 season only.
