'All thoughts go out to Liam and family' - O'Neill
Martin O'Neill has good cause to remember Liam Miller.
He was the manager who gave the young Cork lad his debut in first team football, was the boss when Miller announced himself on the big stage with a couple of Champions League goals for Celtic, and had to watch as Miller made what turned out to be a disappointing move to Manchester United.
Football aside, O'Neill has a clear understanding of what Miller will be going through now that his cancer diagnosis has become public.
O'Neill took a step back from football to nurse his wife through her battle with cancer, and then he witnessed former players from the Celtic days like John Hartson, Alan Stubbs and Stilyan Petrov suffer with the disease.
All survived, but O'Neill was aware of their pain and will also know what not only Miller but his family will be going through.
"I gave Liam his debut at Celtic, he did wonderfully well in a Champions League game one evening. He was outstanding," O'Neill said.
"The news we heard just recently, we did not know how bad it was. Obviously, all thoughts go out to him and his family and he's got three children as well. He's a very young man, 36 years of age. It puts things in perspective, does it not?"
Miller's fame was known as he played first-team football for clubs in Scotland, Denmark, England, Scotland (again), Australia, Ireland and the USA.
And while Manchester United, Celtic and Leeds expressed their support online, Danish side Aarhus (where Miller was on loan in 2001) also said that Miller was not forgotten there.
