Speaking ahead of Saturday's FA Cup final against Chelsea, the City boss joked about speculation that it could be his final trip to Wembley with the club.
"Yes, of course, 19 titles in 10 years is not bad," Guardiola said, smiling. "They know, they don't need to wait when I'm leaving. They know I've been fun. I've been fxxxxx fun!"
City have won 19 trophies under Guardiola so far, with the Spaniard now targeting a 20th before the end of what would be his 10th season in charge.
He added: "Nineteen titles - fighting for the 20 in 10 years - it's not bad, honestly."
When asked directly if Saturday could be his final Wembley appearance as City manager, Guardiola dismissed the suggestion.
"No way! I have one more year contract," he said, before quickly heading out of the press conference.
The 53-year-old has faced ongoing speculation throughout the season about his long-term future at the club, although he has consistently pointed out he remains under contract beyond this campaign.
Guardiola was also asked about reports suggesting changes in his coaching staff, including Lorenzo Buenaventura and Xabi Mancisidor.
In typically playful fashion, he joked: "I extended the contracts of all of them for three more years," before immediately admitting: "No."
Despite the rumours, he insisted he would understand if staff chose to move on.
"As with the players, if you're not happy, you just have to knock on the sporting director's door and get an agreement with another club," he said. "What sense is there to stay? It's the same with the backroom staff. You have to follow your dreams. Life is too short."
For now, though, Guardiola's focus remains on finishing the season with another trophy before attention inevitably turns again to what comes next.
