Miller will arrive at Old Trafford in July having signed a pre-contract with United after turning down a new deal with Celtic.
O'Neill was keen to keep the young Irishman and was saddened to see him walk out on The Bhoys.
"We made Liam and his agent an excellent offer and they didn't take it," said O'Neill.
"It is their prerogative to do that six months down the line.
"He was starting to make good progress, he's been basically injured for the last three years, certainly for half that time and we all knew he had the ability.
"He was starting to really progress and push on like in the European matches against Anderlecht and Alex Ferguson happened to be at that particular game too, but all of those things are my own view.
"I would say this, we are not talking about a man of 30 years' experience and I think at least for another 18 months he should have been looking to play at Celtic.
"We could offer him all the things absolutely ideal for a young man in terms of playing football and enjoying everything he wanted at the football club that would be my view.
"Until things are signed and sealed you can always be hopeful, but I am disappointed no doubt about it."
