Antic's side edged out the Indomitable Lions despite twice going behind but regardless of the result he expects a more conservative approach from his players when there are points at stake.

"We did a lot of good things but there were some that I'm not satisfied with," Antic said.

"Despite the positive result, we have not given enough importance on keeping the ball.

"But I am sure we will be better. I am sure that the team will have a completely different look in the first game in Mondijalu."
