In all his years involved in football across the world, FFA boss James Johnson admits he's never encountered a situation such as the one facing Matildas coach Ante Milicic.

The decision to delay the Tokyo Olympics until next year due to the COVID-19 pandemic has left Milicic caught between his current position and his future posting as the head coach of A-League expansion outfit Macarthur FC.

Milicic's contract as Matildas coach expires at the end of the national team's Olympics campaign.

That dovetailed nicely with preparations for Macarthur's first A-League season at the end of 2020 but now it's unclear just what the ex-Socceroos forward will do.

"This is an extremely unusual case," Johnson told AAP. "In all the years I've worked football administration and all the different jurisdictions I've worked in, I must say I've never quite seen anything like this."

The situation means Milicic can either remain as Matildas coach until the delayed Games and either forgo or delay his move to Macarthur or quit his role with the national team to join Macarthur.

Milicic could also possibly attempt to fulfil both roles although AAP understands that option is highly unlikely to be the outcome.

Whatever decision is taken, Johnson says the issue isn't a priority for FFA as it attempts to restart the A-League and grassroots football across the country.

"It's not something though I think we need to resolve today," Johnson said.

"I don't think we need to open up a new process today for a new coach because the reality is national team football is going to be the last area of our business to reopen because of the movement across international borders."
