The 21-year old New Zealand international has been tracked by Liverpool, Juventus and German Bundesliga clubs this season but insists he will not think about his future until after the A-League finals series.
"Nothing's happening at the moment," Rojas said on Wednesday ahead of Sunday's semi-final against Central Coast Mariners.
"As far as my personal decisions go, we're still going over it, Dad (my agent) and me.
"Once the season's finished, I'll be able to speak about it a lot better."
He added of the interest: "It's gone quiet for a while, so that's been good.
"It's not an individual sport, so I've got to put that behind me and focus on the team.
"If I focus on that too much, it'll affect my performance - and I don't want that to happen.
"I want to do well in this next game, and do well for the team."
