Guardiola is now in the penultimate year of his deal at the Etihad Stadium, where he has been in charge since July 2016.
After replacing Manuel Pellegrini at the helm, the former Barcelona boss has won three Premier League titles, four EFL Cups and the FA Cup during his tenure with the Citizens.
The 50-year-old revealed he does not plan to extend his stay with the club, and that he is targeting an opportunity with a national side.
“After seven years at this team, I think I’m going to have to stop,” he said at an XP Investimentos event.
“I’m going to have to take a break, see what we’ve done, and review inspirations.
“And in the process, I would like to coach a national team – South American, European, playing a Copa America; I want to have that experience.”
However, Guardiola talked down his chances of succeeding Tite as head coach of Brazil.
The City boss feels the current crop of Brazilian stars are unfairly compared to their predecessors of yesteryear, but he insists they will be one of the favourites at next year’s World Cup in Qatar.
“Current teams will always lose to history,” he added. “If you compare this Brazil with Pele’s, with the [World] champions of 1994, the current one will always lose.
“But if you ask me what I think of Tite’s team: fantastic. Some are my players, others are rivals’ players, but they’re fantastic.
“If you compare them to the past, teams from the past always win because they don’t play anymore. But Brazil are always a favourite – in the Copa America, in the World Cup – always have been and always will be; it’s part of their culture.
“I think the coach of the Brazilian national team will always be Brazilian; I don’t see a foreigner at teams like Brazil.”
