The Portuguese, 60, was in charge of Real Madrid at the time.
Chatting to the late Grant Wahl, Mourinho praised the American mentality.
After being sacked by Roma yesterday, the former Chelsea, Manchester United and Tottenham boss could look to finally make his move to the States.
Talking to Sports Illustrated, Mourinho said: “I see myself coaching a [club] team, coaching the national team or helping develop soccer in the US.
“When I’m tired of winning things in Europe, it’s something I want to do.
“I want to coach the Portuguese national team and I want to work in the United States.”
Mourinho, who has been on plenty of US tours with his various clubs down the years, adores the American way of life.
He added: “I love it. The people have a very open mentality.
“Everybody is the same. Status doesn’t count a lot. I like it very much in this way.”
