He told the News of the World: "I couldn't see myself coaching any national team other than Portugal. If I were coach of another team and had to face Portugal, it would be wrong.
"I'd like to continue in club management, perhaps in Italy where I can test myself against their tacticians. The national team would be for later. The Portuguese national team is an ambition but not for the Jose Mourinho of today.
"Being the coach of a national team is not the same as being coach of a club. It's a job for someone who doesn't like working much."
And Mourinho insists that bringing in coaches from overseas to lead international sides is wrong.
He added: "I'm completely against having foreigners with national teams, not because I doubt the professionalism with which they do it, but I think that a national team should bring together the best players and the best coach from each country.
"The national team is an obsession for me but it will be at the end of my career. Let there be no doubt about that."
