Former Blues midfielder Lampard criticised his players for lacking the urgency to beat Bournemouth's impressive low block, in the same way Chelsea struggled in recent losses to West Ham and at Everton.
"In front of our home fans it's clear now that we're not playing well enough, not getting enough results," said Lampard.
"We just didn't get the fans excited enough.
"The fans shouldn't be excited if we're going to play 10 balls across the back four, they shouldn't be. And that's not the team I want to manage.
"I'm a Chelsea man and everyone knows that, and I would be the first to say if the fans were flat.
"But today I'm never going to say that, because if I was a fan sitting there today I'd also be saying 'too slow, too slow, centre-back to centre-back, centre-back to full-back, back to centre-back, back to full-back'. And I don't want to come and see that.
"So I won't blame the fans, they come here to support the team, they will come to Tottenham next week and they'll come to Southampton on Boxing Day.
"And some responsibility is on the players to excite them, to have the personality and have the b***s to take the ball in an area and beat someone or play forward.
"We need more urgency in our play, if you're transferring the ball, transfer it quickly.
"If you're playing through the lines, if you're an attacking player, get at people, do things that are positive, don't play safe. We play generally too safe through the game."
