Norwich City football chief Stuart Webber says they must stay level-headed this season.
The Canaries have shocked Manchester City, before being thrashed by Aston Villa.
Webber told the club's website: "We can't get too high and we can't get too low, so after we beat Man City we can't walk round and convince ourselves that we're going to win the Premier League this season. Likewise, we can't lose at two incredibly tough places to go in Crystal Palace and Burnley and against Aston Villa at home with all the problems that we had and then want to jump off a cliff.
"We've got to stay level, that's the supporters as well. I personally thought it was a little bit flat on Saturday, even when it was 0-0. I don't mean when it was 5-0, because listen I appreciate people want to go home at 5-0 and do their shopping or whatever, but we can't take it for granted that winning games in the Premier League is easy. It's not, because if it was everybody would be doing it.
"We've been on a tough journey to get here. We climbed Everest last year and we've gone back down to the bottom to try to climb it again. That was always going to be hard and what we can't do is lose our nerves after a couple of bad games. Likewise, we can't go to Bournemouth and win and think we need to get into Europe."
