Brisbane Roar broke the news saying Aloisi would depart the club "effective immediately".

The former World Cup veteran was appointed head coach in May 2016 and was in his fourth season with the former A-League giants.

Assistant coach Darren Davies will take the reins in the interim with his first test an away trip against Sydney FC on Saturday.

Despite the poor results, Aloisi was bullish after each match saying the team would come good, but four straight losses including last week's dismal 4-1 defeat to Wellington finally told.

Following today’s decision Aloisi said: “For the past three and a half years, I have given every minute of my life to make the Brisbane Roar a success.

“Upon reflection of the current situation, I have made the difficult decision to stand down effective immediately as I believe this is in the best interest of the playing group and football club.

“Everybody knows the challenges of the past few years and I’m proud to have made the finals each season, qualified for Asia and have gone within a point of winning the Premiers Plate amid all of that.

“I cannot thank the players and football department enough for their support during all of the obstacles we have collectively faced and wish everybody connected to the club – the owners, the players, the fans and the staff – the absolute best for the balance of the season and beyond.”

Between 2015/16 and 2017/18 Aloisi led Roar to two third finishes and a 6th but the club was beset by off-field dramas.  

After announcing his departure the club thanked Aloisi for his "dedication and service".
