Johnson is as excited as anyone about what the future may hold for City but he is refusing to get carried away.
He said: "They are exciting times at City. Yes, absolutely. But I think we've just got to take each game as it comes.
"A lot of people are saying we are going to do this and that but we are focused on ourselves. We've started reasonably well and we've just got to carry that on, keep winning and see where it takes us.
"Like I said, these are exciting times but we are not getting too carried away with ourselves."
