The veteran defender is shocked the Blues sit just above the relegation zone after seven Premier League games.
Hibbert, 33, said: "Football is funny.
"It's hard to figure out why it hasn't worked for us, it just happens.
"We haven't started the way we wanted to but it will come. We'll click again. We showed what we can do towards the end against United.
"The games will come thick and fast again after the international break and we just need to get our confidence back and get going again.
"We just need a win. We're not playing badly. We need to believe in ourselves more because we've still got the players we had last season. It's only a matter of time.
"Hopefully after next weekend we'll have some of the injured men back. A little rest and then we'll kick on again."
