The 25-year-old fringe Socceroo will become one of Brisbane's two marquee players next season, while Broich - who would have needed to come under the salary cap to stay - will seek a move after receiving no guarantees from the club regarding a new contract. Just a couple of weeks ago he decided he did.
"It's very hard to explain to the general public what goes on behind closed doors but Thomas Broich for me has been a joy to coach".
"I didn't even make a decision".
"It was something that Thomas made and we respect that and now we're just focused on the game".
Since 2010, German midfielder Thomas Broich has been a fixture at Brisbane Roar.
"I would have loved to have been able to work out something that would have kept Thomas here until the end of his playing days", Aloisi said. After training, during training, we've got that relationship and I think that will continue on past this season.
Broich said that Aloisi didn't know if he could offer the two-time Johnny Warren medal victor a new deal, nor how much any contract would be worth.
"Bosnich continued to talk of the A-Leagues salary cap, which some feel is restricting the league in competing with big spending Asian competitors such as the Chinese Super League".
Brisbane will face Melbourne Victory in an away semi-final if they win, while a Wanderers success sets up a tantalising Sydney Derby. That's part of it.
"There's always going to be questions asked about players who play the same position but from my perspective, I don't really see it that way".
"He's not really focused on the fact this might being his last game", he said.
Brisbane Roar boss John Aloisi has lauded outgoing star Thomas Broich's attitude ahead of their make or break elimination final against Western Sydney Wanderers at Suncorp Stadium on Friday night.
Aloisi added that his side are not seeking revenge for a 5-4 semi-final defeat against Western Sydney last season. "The boys owe him everything we can give to maximise the chances of that happening", Oar said.
"That hurt that night because we wanted to go to the grand final".
"Whether it was against the Wanderers or it was against someone else, there's no revenge here. We want to go all the way".
