The Blues are currently in third place in the table after Lampard’s double secured a 2-1 win at Everton on Sunday.
Chelsea are four points behind second-placed Manchester City but have a game in hand.
And Lampard is convinced that Rafael Benitez’s men will continue to challenge for the title ahead of Wednesday’s clash against rock-bottom Queens Park Rangers at Stamford Bridge.
“Of course we can still win the league, it is possible,” said Lampard.
“If we concentrate on ourselves, win our games, put a long run together and we can put pressure on Man United, who knows?
“It’s the position we’ve put ourselves in because we had a funny run in November and December and we were top and now all of a sudden we are adrift – but we can’t look back at that.”
Chelsea are 11 points behind Premier League pace-setters Manchester United.
