Solskjaer has now led Molde to back-to-back titles in Norway.
"The squad I have at Molde is very young and after winning the title last year we brought in some new faces. But you have to do your homework. We brought in the right characters and personalities. The players we have recruited have been key to our success," Ole told the Manchester Evening News.
"I learned from Sir Alex the value of getting in the right people. It was always said at Old Trafford that the best players are the best people. Players like Scholesy, Giggsy, the Nevilles, Becks, Denis Irwin, Roy Keane and Edwin van der Sar, they were all the best people and the best players.
"They had the qualities of recovering from failures and not getting too far ahead of themselves when they'd done well.
"I brought in players to Molde who are hungry. I've brought in players who don't want to stay with Molde for the rest of their careers. If they want to have ambitions of playing in the Premier League or the Bundesliga that is fine by me and Molde will benefit from those ambitions.
"I have a lot of young players here who I have known from when they were 13 when I had an Academy over here while I was at United.
"You get to know their characters and personalities and you know the ones with the right mentality.
"It is the key to keeping Molde at the top that you bring in players who are ambitious and you don't stand in their way if the right offer comes in for them. You let them go and pursue their dreams and get in other new talent. Molde is not the biggest club and you can't expect players to want to stay around for the rest of their careers when there is so much out there in the world.
"It has to be a springboard for something bigger. I know that from my own experience. I got the chance to go to United because of that and I am not going to stop anyone having that right to improve themselves."
