Defender Joe Jacobson says confidence is sky-high at Boundary Park following Oldham's unbeaten start to the season.
Paul Dickov's men are yet to taste defeat after five League One matches and travel to fourth-placed Peterborough on Saturday.
And Jacobson said: "There is a real buzz around the place at the moment and everyone is enjoying it and feeling good about themselves.
"Mentally, we are going into every game feeling like we are going to win - which is how the new management want us to think. They have stressed that we need to believe in ourselves."
