The Swede played for Moyes at Everton.
Blomqvist told the Daily Mail: "I had been released at United by Sir Alex Ferguson and was slowly but surely rebuilding my career at Everton, when Moyes took me to one side and said: 'Sorry son, I'm not keeping you on.' It was a hammer blow that ended my time at the top of English football.
"It revealed a side to him that should stand him in good stead for the challenges lying in wait at Old Trafford. It wasn't just the ruthless streak that is surely a prerequisite for managing a club such as United, it was the way he went about telling me.
"It had nothing to do with the way I reacted to being substituted against Bolton a few weeks earlier. As I waved an arm and found a seat behind him in the dug-out, he leaned back and let me know, in no uncertain terms, that he would not tolerate conduct like that, even if he did understand how I felt.
"I don't believe that episode influenced his thinking, but he still ended up showing me the door. He told me straight, face to face, and he went through his thought process step by step. I couldn't have asked for more and I left the room still feeling the same respect for him I'd had at the outset."
