Frank Lampard admits Chelsea have not worked hard enough to arrest their alarming slide down the Barclays Premier League.
England midfielder Lampard believes a lack of confidence and quality have also played their part in the club's worst run of league results for almost 15 years.
"There was a time like this near the end of the Luiz Felipe Scolari reign when we were struggling to get wins," said Lampard whose two goals in Sunday's 7-0 FA Cup thrashing of Ipswich went some way to lifting the gloom at Stamford Bridge.
"Everyone has spells like that to an extent but this one has been a little more prolonged over a period of time.
"That's the upsetting thing. It is certainly time for us to change it now. Not winning games is the biggest thing that has affected us.
"There are quite a few reasons for that, a lack of confidence being one of them, but there has also been a lack of quality and workrate. We need to step it up across the board to get back to where we want to be."
