The Irish star, who played more than three years in the A-League, tragically lost his battle with pancreatic cancer today.

Fans and players took to social media to express their shock and dismay at the death of the former Ireland international.

In a much travelled career he played for 12 clubs including Leeds, Queens Park Rangers and Hibernian.

He won the Scottish Premier League with Celtic in 2003/04 and the Championship with Sunderland in 2006/07.

A gifted playmaker, Miller starred for Perth Glory between 2011-13, and also had stints at Brisbane Roar and Melbourne City.

He won the Premiership-Championship double with Roar in 2014. 

After leaving Australia he played for his hometown club Cork City before joining Wilmington Hammerheads in 2016.

News of his illness first emerged in November last year.
