Resurgent A-League champions Brisbane Roar have yet to pass their biggest test, coach Mike Mulvey says.
After a woeful start to their title defence, the Roar could find themselves in the top six by the round's end following their 1-0 away win against Adelaide United on Saturday night.
Mulvey couldn't hide his pleasure at the result, with the scoreline not fully showing Brisbane's dominance of the third-placed Reds.
"It was probably as dominant a 1-0 win as I've been involved in for a while," Mulvey said.
The Roar had 57 per cent possession and twice as many shots on target than the Reds, with Ben Halloran's 82nd minute goal sealing a deserved triumph.
"If you keep knocking at the door, something is going to happen for you," Mulvey said.
"It took us a long time. As we said at halftime, if it takes us until the 95th minute, let's just keep playing the way we're playing.
"We could have easily been a couple of goals up at halftime."
But Mulvey said his club's biggest test was showing such ominous form consistently, with games against powerhouses Melbourne Victory and Central Coast in the next fortnight.
Brisbane took sixth spot but whether they hold it depends on Melbourne Heart's result against Wellington on Sunday.
"It is well documented we're not happy with where we are on the table and we're trying to do something about it," Mulvey said.
"It's the business end of the season.
"We have been working very hard and ... we're still the masters of our own destiny.
"The key thing now is can we do that again next week - that is the big test."
Adelaide, while still third, have just one win from their past seven games and their caretaker coach Michael Valkanis was seeking the same trait as Mulvey - consistency.
"We have to find that consistency quickly, we have to find the players that will stick to the game plan, that will stick to the things we're working on and consistently do it," Valkanis said.
"It has to become habit. We will force it to become habit and keep working on it."
