The Toffees are the last side to hold an unbeaten record in the Premier League, with manager Roberto Martinez continuing a fine start to life at Goodison Park by beating Newcastle United 3-2 on Monday night.
He told The Mirror: "City have either been amazing or a little bit naive, so we're still seeing with them. But we have to be confident we can go there and win.
"The way the league is panning out, no-one seems to be taking charge or has been invincible, and we have given ourselves a good enough start that we can go there and be positive and see where it takes us.
"Nobody is right on it at the moment, so we'll have a good go and hopefully this isn't just a flash in the pan and we can keep our unbeaten record going."
Under previous boss David Moyes, the Toffees won six of their last eight meetings against City.
