In a rut: Lampard has highlighted Chelsea's malaise
The reigning Barclays Premier League champions are currently on a run of just one win in their last nine league matches, and with boss Carlo Ancelotti under increasing pressure, the England international fears it will take time to regain the belief that won them the title last year.
Lampard said: 'At the moment there's a bit of a feeling that we're not sure what's going to happen when we go out there. If we're honest we all think that. That's just the way it is. You can't help that.
'The end of Phil Scolari's reign was a bit like this. You lose the feeling of being able to win every week. Once you've had that and lose it, it's hard to get it back.
'We won the Double last year, all of us together including Ray. Ray is no longer here.
'But the club makes the decisions and, if Roman Abramovich wasn't here, we wouldn't have won three Premier League titles.
'Things are important off the pitch but we've been putting out a side good enough to beat teams we've lost against.
'What we can't do as individuals is use what happened to Ray as an excuse. We have to perform regardless.'
Lampard also admitted their have been tensions between the big personalities within the squad.
John Terry and Didier Drogba have argued on the pitch recently and the 32-year-old midfielder said: 'If you aren't winning games there would be something wrong if the big players didn't start asking questions of each other and themselves.
'Drogba is known as an emotional character and John as well. Ideally it should be done in the dressing-room, but when you want to win it can come out on the pitch.
'I'm sure everyone expected us to beat Wolves and get back in the title race but they deserved to beat us.
'his is a bad moment, make no mistake about it. We don't have to hide it any more. It has been a long enough time.'
