The Roar have been in training for some time now as Postecoglou and the rest of the coaching staff look to mould a side that can compete for the title and the way things have gone so far, it all looks rosy in the Brisbane camp.
"Pre-season is tracking well so far," Postecoglou said.
"We've been going for about five to six weeks so we've got a bit of a way to go ... but overall I'm really happy.
"The new players are fitting in well and we still have a few additions to add to the squad.
"Currently we are still looking for a new striker and defender."
Postecoglou added that his trio of new players were training on well although none of them were at full tilt just yet.
"Shane Stefanutto is coming off his knee reconstruction but he is working hard and is on track to come back when he was originally slated to," Postecoglou added.
"Thomas Broich has fitted in pretty quickly, but obviously it will take a little while for him to understand the game here.
"Rocky Visconte is a little behind in terms of fitness so were doing some extra work with him, but I expect them to be ready to go come the start of the season."
