Mourinho has spent all of his managerial career to date at clubs, having spells at Benfica, Porto, Chelsea, Inter, Real Madrid, Manchester United and Spurs.
Though he is in no rush to call time on his time in club management, the 57-year-old disclosed he does wish to step into international coaching eventually.
"Yes I want to coach a national team, I want to have the experience of a World Cup and European Championship, the emotion of the short competition," Mourinho told a news conference ahead of Spurs' Europa League qualifier against North Macedonian side Shkendija.
However, Mourinho is not convinced coaching his home nation would be the best choice.
"Is Portugal the one I want do do? On one side yes as it is my heart," he added. "But it is very difficult to do it with the country you were born in."
Mourinho, who returned to his news conference to field a question from a Macedonian journalist whose late father idolised him, is also anticipating a tough test for Spurs on Thursday.
"My experience in football, I celebrate the 20th anniversary of my career, lots of experience, played lots of teams that nobody knows in top football," he said.
"They can be very dangerous, same way it was difficult in Plovdiv."
