It’s an ominous warning to their A-League rivals but Brisbane Roar defender Ivan Franjic feels the competition leaders should strive to get even better.

Seven points clear on the A-League ladder, having just posted back-to-back wins in which they scored eight goals without star striker Besart Berisha, things can’t get much better for the Brisbane Roar, right?

Not in the opinion of Socceroos defender Ivan Franjic, who feels the Roar can improve as they aim for an even more-dominant second half of the season.

Franjic, a key element of the Roar’s success, says he and his teammates are striving to string together a run of results similar to their record 36-match unbeaten streak during their back-to-back premierships in 2011-12.

While Brisbane are clear league leaders this year, their 10 wins have been interrupted by three losses with four straight victories before a 2-0 loss to Newcastle in their last home outing their longest unbeaten run so far this season.

After a 5-2 win over Sydney FC on Boxing Day and a 3-0 drubbing of Melbourne Victory last weekend, Franjic has challenged his teammates to put even more pressure on their rivals by stringing together several positive results.

“This is what we planned to do midway in the season – be on top and open up a gap in the league, which we’ve done.

“Hopefully, we can continue that in the back half of the season which is the most important bit of the season.

“It’s important to get some consistency now. We’ve had two great performances so, if we can continue that, we’ll really come home strong.”

Franjic says no one at the Roar is allowing complacency to creep into their games, with the defeat to the Jets in Brisbane before Christmas a wake-up call for everyone in the squad.

The 26-year-old says Saturday’s visit by Adelaide United is a chance for the team to make it up to their home fans.

“I know here everyone’s got their feet on the ground which is a good thing,” he said.

“We’ve just got to go out week-in, week-out and keep getting results.

“At this moment, we don’t fear anyone in the comp and that’s where it should be.”
