A home win would put Liverpool - who were pipped to the title by Guardiola's side in May - nine points ahead of City, who have managed one league win at Anfield since 1981.
"Regarding statistics, I don't believe much in that kind of thing," he said.
"Statistics are OK but I'm thinking of what we have to do to beat them."
Guardiola added: "It is the people in the media who say we are outsiders or not, or we are the underdog or not.
"I never went into one game feeling like an outsider or that I am not going to win the game. I never felt that. Never. I am not going to take a bus to Anfield on Sunday thinking I am going to lose the game."
