Swindon boss Mark Cooper has suggested midfielder Massimo Luongo could leave the play-off chasing League One club at the end of the season.
Luongo told Australian broadcaster SBS in February he wanted a "new challenge" after two seasons with the Robins.
The 22-year-old Australia international has scored six goals in 33 appearances for Swindon this season.
"If it's time for him to move on, it's time for him to move on," Cooper told BBC Wiltshire.
Luongo made his debut for Australia in March 2014 and was named player of the tournament at this year's Asian Cup - having scored in the home nation's 2-1 extra-time victory over South Korea in the final.
"Obviously if I keep doing what I'm doing here, I probably know for myself I won't be here next year," Luongo told SBS.
"I don't think many people would like to hear that, but it's probably fair to say that it's time for me to move on."
Swindon are fourth in League One, 10 points outside the automatic promotion spots, but 11 points clear of Rochdale in seventh.
And Cooper said Luongo needs to sustain his level of play if he is to earn a transfer to a bigger club.
Cooper added: "Massimo's obviously a very ambitious young man, he's been and played on the international stage and done very well, and he'll know there are eyes being cast over his play.
"He's got to keep playing and playing well to get the best move that he possibly can if he is going to go. I've got no problem with people being ambitious."
