Guardiola has refused to sign a long-term contract with Barcelona as he prefers one-year extensions.
“Every day I think that I’m leaving the day after. I work better when I know that I have the freedom to decide on my own future,” he told Sport.
“There is a risk that you lose your passion for what you do when you sign a long-term contract. It is all about passion. The biggest wealth that someone can have is doing something that you really like. That is the essence of everything in my opinion.”
