Solskjaer led his former club Molde to their first Norwegian title last year, after starting out his coaching career with the United reserves.
"He's got an inner toughness, there's no doubt about that. He's a nice man with a lovely manner about him," Ferguson said.
"If you go to a club in Norway that has never won the league ever in their history and you win the league, you have to have something about you to do that.
"He has brought in his own staff. He's brought two coaches from United to the club so he knew where he was going. A useful thing to have in management is good decision making."
Solskjaer has been tipped as a potential successor to 70-year-old Ferguson at Old Trafford.
