Obama said: "What he (Trump) has to appreciate is as soon as you walk into this office after you've been sworn-in, you're now in charge of the largest organisation on Earth.

"You can't manage it the way you would manage a family business."

Obama added he and Trump are "sort of opposites in some ways".

In an interview with ABC America's This Week program, where Obama singled out their contrasting approaches to policy matters.

Obama said he was on the "policy wonk" end of the spectrum, in contrast to Trump.

He said: "I think that he has not spent a lot of time sweating the details."

The President warned that quirk could give Trump fresh perspective once he takes office, but it also could blindside him.

He added that: "There are world capitals and financial markets and people all around the world who take really seriously what he (Trump) says."
