With Burns, Djite, Williams and Vidic. A couple of them should have made of squad to give us more options. But at the end of day none of them scored many goals during the qualifies. Milligan and Sarkies were leading goal scorers in qualifiers. There was no formation that worked with Williams or Burns in the side, both basically played as wingers when we had two strikers in XI. Vidic never got a game due to him and Spiranovic prefering to stay in Germany and push for starting spots at Nuremburg.
Even if these guys did make the squad I would have had them behind Bridge and Thompson. Ruka got potential but is even further away from being a finished product then Burns, Djite, Williams or Vidic. Which was the claim used by Arnold was his selection ahead of them.
Holland was the other big name player, considering he was a regular in Socceroos squad lately. But as I guess with Musalik and Milligan playing holding roles in midfield he would have been just a bench player.
End of day though if you look back at past Olyroo squads guys like Niell, Bres, Grella, Holman, MacDonald, Carney, Culina, Thompson and Kennedy. All played bit part roles or got rejected during the time they were at that stage during their career. Australia never had great history of picking future Socceroos in Olyroos squads.
