Sorry I had to chuckle at 'overcrowded FIFA calendar'. From our perspective at least...
But for Socceroos is complete opposite, esp now they have been invited to Copa America.
FFA are already saying an AWs game would be 2022 at the earliest!!
Opportunity was actually possibly there in November window last year when they had just one game in Jordan. So rather than AWs playing Lithuania, could have been a game verus Socceroos in London following AWs Irish game?? I'm sure it's more complicated than that, but sometimes wonder how much NZF and FFA talk to each other.
For 2020 the Socceroos have 2 WC qualifiers in March window (Nepal & Kuwait), another 2 qualifiers in June (Jordan & Chinese Taipei), then straight after fly to South America for Copa America and minimum 5 games there.
I imagine then further World Cup qualifiers in Sept-Oct-Nov 2020 windows.
