Rescuing Roar 'not an easy job' - Thijssen
Title-winning boss Mike Mulvey was sacked on Sunday after recording just one win from six matches this season, to be replaced on a temporary basis by Thijssen.
The Dutchman will share coaching duties with director of football Ken Stead, before moving to a technical director role next season, following the appointment of a long-term successor.
"I am happy to be in Australia," Thijssen was quoted as saying by Brisbane Roar's Twitter account.
"I know this is not an easy job.
"The training session this morning was very sharp. Hopefully we can turn this season around."
Asked at a press conference if Mulvey had lost the dressing room or fallen out with senior players, Smith said: "It's upset the playing group that it's come to this."
Pressed on how much responsibility rests with the squad for Mulvey's departure and the team's poor form, the captain added: "We're the ones that go out there on a Saturday afternoon and perform."
"Do I like where we're placed at the moment? Of course I don't.
"Do I take a slice of the accountability? Of course, I'm captain of this club. I can't sit here and say I'm happy."
