Brendan Rodgers is the latest to join a stoush brewing between FFA, Graham Arnold and a range of club sides around the world.
The 23-man Socceroos squad for the 2019 Asian Cup has been named, and despite substantial injury fears over Aaron Mooy and Tom Rogic, both have been included.
Mooy's inclusion, only days after he uploaded a photo in a moonboot, sparked a series of back-and-forths between his club, Huddersfield, and FFA who sent private medical staff to perform an independent assessment.
Now Rogic is the latest Aussie to have the timing of his inclusion questioned by Celtic boss Brendan Rodgers, as meeting up with the squad will see him miss a Scottish Premier League match against Aberdeen.
"We hope we can find a sensible solution," Rodgers told BBC Scotland.
"At this moment in time he's due to play his last game for us away at Aberdeen and then he's due to fly out to meet up with the Australian squad on the 27th so that would mean him missing the last game.
"That's not something we're overly happy about because we want to work in a relationship with the federations.
"I spoke with Graham Arnold, the manager, here and I had two really good days of trying to ensure relations are good between international teams and club teams.
"But you do that through working together and what is the best for each player. And we feel Tom can play and be available for the 29th and fly out after the game and meet up in Dubai on the 30th and still be there virtually a week before he's due to play his first game.
"Tom wants to play in the game but he also wants to play for Australia. It's a position the player doesn't need to be in."
Rodgers isn't the only SPL coach affected by the Socceroos' Asian Cup squad, with Hibernian and former Celtic boss Neil Lennon set to lose Martin Boyle, Jamie Maclaren and Mark Milligan for the tournament.
"Neil's in a similar position in terms of he's got three players, one of them they didn't even know about until he told them," Rodgers added.
"Again, building relations. I think Neil told them about Martin Boyle and all of a sudden he's lost him for a big derby game. I don't think it's a sensible solution if I'm being honest.
"It's disappointing if we can't find a solution but I'm hopeful that they can see sense with it and see that they could still get their players in good preparation time and be ready for the tournament's start."
