Solskjaer, who now manages Molde, scored 126 goals during 12 seasons with the Premier League outfit, but he was more known for his 'super-sub' tag than as an established starter.
"It was obvious that his desire was to be a coach... but more than that it was a desire to be the best you can be," wrote Ferguson in his new book, My Autobiography.
"I'm very lucky that he never complained, I don't think any other player of that quality would have stood for it.
"Teddy [Sheringham] always moaning at me, and I can understand because he was a great player... but Ole never complained. He had that fantastic patience."
Solskjaer also scored 23 goals in 67 games for Norway.
