Former Manchester United boss Jose Mourinho admits coaching a national team is an ambition.
Mourinho says Portugal would be a priority, but not his lone choice.
He said: "I think it's more of the national team than a club. But you can never say never.
"But I see more of a national team than a club project. Because it's something I've always lacked. It's something I'd like to do. Not only Portugal, but also the work of (any) national team. It's something I've never wanted until now and I'm still not at this moment in my career, in love with that kind of work. But it's a job I'll want to try one day.
"A lot of people say it's easier to be a national team coach than a club coach. There are others who say it's easier to be a club coach than a national coach because a national coach only sees players once a month for three days before the game.
"I've always refused that. They're jobs that have virtually no point of comparison. The only point of comparison is to win.
"I'm going to want to try that side of our profession one day. I'm going to want to do a European or World Cup, which I've never done before. I'm very curious about this role as a national team coach.
"By the way, we're going to win the League of Nations."
