Some incredibly sad news began to emerge last night that former Irish worldwide Liam Miller was gravely ill, fighting cancer.
The former Republic of Ireland player is reportedly receiving treatment in the United States, where he last played for Wilmington Hammerheads.
"Obviously we heard the news", the Hull City midfielder said on Monday.
McManus added: "He starts chemo tomorrow and is fighting hard really can't go into any more detail than that out of respect for him and family".
Liam Miller won the A-League premiership and championship with Brisbane Roar in 2014.
Pat Malone, chairman of Éire Óg where Liam played as a child, said the whole community was rallying in support of the family.

He was fined $10,000 for the infamous post but has since denied that it had anything to do with the Arizona-based franchise. Antetokounmpo has already been singing the praises of his new teammate and described it as "easy" playing alongside him.
"He played with us and with soccer clubs in the area".
The 36-year-old began his career at Parkhead, scoring two goals in 26 appearances during the Martin O'Neill era before moving to Manchester United.
Speaking at his press conference this morning ahead of the second leg of Ireland's World Cup play-off against Denmark, O'Neill offered his support to the former midfielder.
"Awful news about Liam Miller keep the fingers crossed that he somehow pulls through", McManus tweeted.
Fellow former United player Danny Higginbotham said: "If true very sad news about one of my former teammates Liam Miller".
Ex-Ireland team mate Noel Hunt tweeted: "Such sad news about my old room mate Liam Miller. Will say a prayer for him tonight".
