Do you think Singh will come back for the friendly? Im not sure his club will let him go.
Don't think so, Bayern II have had a real rocky start to life in the 3. Liga so they'll want him
Really it's a bit pointless bring any U23 players based in Europe, back to play the Olyroos.
These 2 games are warm ups for the Olympic qualifying tourney in PNG. That tourney is not in a FIFA window.
Maybe some players in Euro youth setups, or out on loan etc (Mata, Oli Whyte, Ellis-Reid, Just, Wilkins the Torslanda crowd) - could be released for PNG, but Singh certainly won't be. So pointless bringing the likes of him, Woud etc all the way back to Australia, when he won't be in PNG a few weeks later. Very much doubt Bayern would be happy about it either.
Buckingham must be scrambling around making ph calls, trying to work out who he can call up, as much as any coaching planning.
Good news is that the very much U23 'B' team he took to Samoa, proved the big names may not be needed.
