Former Ireland international Liam Miller has been released by his club Brisbane Roar amid rumours that the Cork man refused to play for the club’s National Youth League side.

Miller was dropped after Brisbane's opening-day defeat to Adelaide and only managed 13 minutes of first-team football in the round two and three defeats to Perth and Sydney.

A story in the Courier Mail reported that Miller was expected to play for the club’s NYL side and coaching staff had to make last-minute changes when the former Manchester United midfielder failed to show.

Roar coach Mike Mulvey then stated that Miller was struggling with a calf injury, which was the reason for the no-show.

“He’s just not 100 per cent right at the moment,” said Mulvey.

“He’s still got an issue with his calf and it’s not recovering properly.

“He’s had that problem for a while now and we’re hoping it fixes soon.”

But the Queensland club has now confirmed that the former Celtic player had left the club by “mutual consent” and Miller was “granted an immediate release from the remainder of his contract to pursue other football opportunities”.

Miller was an integral part of the Roar’s Premiership and Championship-winning 2013/14 season and coach Mulvey has since thanked the Irishman for his contribution.

Mulvey said: “We brought Liam here to strengthen our squad and play good quality football – he was an integral part of our success as a squad last season and we thank him for his service to the club.

“It’s always disappointing to lose a player of Liam’s calibre but both player and club decided this was the best outcome. We wish him and his family all the best for his future.”

The Cork man scored three times in 24 league appearances for the club since signing in May 2013.
