Celtic and Manchester United have expressed their support for former midfielder Liam Miller after reports that the 36-year-old is battling pancreatic cancer.
The former Republic of Ireland player is reportedly receiving treatment in the United States, where he last played for Wilmington Hammerheads.
Celtic wrote on their official Twitter account: "The thoughts and prayers of everyone at Celtic Football Club are with Liam Miller and his family at this time."
Miller made his professional debut for Celtic in 2000 after coming through the youth ranks at Parkhead and helped them win the Scottish Premier League title in 2004.
