Frank Lampard has said Chelsea must fight to win the Premier League title and not let their standards drop by aiming for anything less.
Last week Blues boss Andre Villas-Boas said
"maybe the Premier League is over for us"
1-1 draw at Fulham
But after Monday's
2-1 victory at Wolves
, Lampard said: "[We can't] drop our standards and just think 'let's just fight for fourth' or whatever.
"We're too good for that. In my eyes we should be challenging for the top."
Chelsea are eight points behind
leaders Manchester City and Manchester United and have a vastly inferior goal difference, having played one game more.
Talking to BBC Sport, 33-year-old Lampard added: "The minute we don't set those standards we won't be the Chelsea we've been.
- Total appearances:
- On as substitute:
- Taken off:
"Look at the talent there is. I get frustrated that we're not fighting for top place at the minute and the points difference there is."
Lampard also admitted it is frustrating not to be a regular starter under Villas-Boas; of the 25 games he has played for the Blues this season, six have been as a substitute, while he has been taken off five times.
"I like to play 90 minutes, I can't hide that," he said.
"[But] he's the boss; he picks the team. But when I play I feel I can do things like I did [against Wolves] and I'll keep trying to do them."
Lampard volleyed Chelsea's winner at Molineux in the 89th minute but admitted he was fortunate not to be sent off earlier on for a mistimed sliding tackle on Adam Hammill.
"My heart was in my mouth," said Lampard, who was booked by referee Peter Walton.
"There was no malice - and I honestly mean that - but I was late and I might have been a bit lucky to stay on the pitch.
"I said straight away to Hammill that I was very sorry. I was trying to get my foot in and I was maybe lucky."
