Hemmed in behind Erik Paartalu for two-and-a-half seasons, Brattan's patience was tested right up until last season as he bided his time for an opportunity.
But, as premiership-winning coach Mike Mulvey attests, the creative midfielder is the epitome of persistence paying off.
It was only 14 months ago that Brattan broke through as a first-choice player under Mulvey, once Paartalu left for China, and he's flourished since.
Saturday night's injury-time wonder strike for a 1-0 win over Melbourne Victory, sealing the premiership with three rounds left, was the icing on the cake.
Despite being part of the 2010-2011 and 2011-2012 championships under Ange Postecoglou, the former Australia Under-23 squad-member has no hesitation in rating this season's premiership his sweetest.
"Even though I did win two championships back then I feel as though, because I didn't play as much, I wasn't a part of it," Brattan said.
"This definitely feels a lot more to me.
"There were times that I questioned my career. Ezza was a fantastic player, he rarely got injured but I came in every day and trained as hard as I could."
The thing that kept the Hull-born, Brisbane-raised 24-year-old with Roar was the quality of his team-mates, headed by German marvel Thomas Broich.
"The players that were in that team taught me a lot," he said. "Words can't describe how lucky I was training with a bunch of players like that, even this season I learn something new every day at training."
Despite copping a hip knock against Victory, and having the luxury of four weeks to freshen up for a home semi-final, Brattan won't rest and will line up this Friday against Melbourne Heart.
Mulvey is a big fan of the "humble" Brattan and felt his story duly represented a Roar side that has returned to the top on the back of a renewed hunger for success.
"Persistence is a great virtue," he said. "How many (times) do you see someone who's not quite in the team pack their bags and move on?
"He's persisted and we're getting the rewards, and he is too."
