I can see him aiming for the portugese national squad
I know ages ago he said that he likes domestic football because he sees players every day, works with them constantly, gets to make changes etc.
If he doesn't want a full break and wants to stay in the game, an international job would be the next best thing (wait till Roy leaves the England job ). It wouldn't be as intense, he'd be guaranteed to be in one job for at least 4 years you'd say (a Euro's, a World Cup and their respective qualifying campaigns).
