Chelsea moved to within four points of back-to-back Premiership titles with an impressive victory at Bolton.
Lampard celebrates after scoring Chelsea's second at Bolton
Ricardo Vaz Te gave the champions elect an early scare when he hit the post but John Terry headed home Frank Lampard's free-kick after 44 minutes.
And Lampard - who scored twice when Chelsea won the title at Bolton last season - fired in the second from Hernan Crespo's pass after 58 minutes.
Bolton then had Tal Ben Haim sent off for two yellow cards as time ran out.
Chelsea could seal the title with victory against Everton on Easter Monday - if Manchester United drop points at Tottenham.
While Chelsea celebrated moving to the verge of more glory, Bolton were a subdued shadow of the side that threatened to seal a Champions League spot only a few weeks ago.
Sam Allardyce's team barely posed a threat after Chelsea took the lead, which led to the Trotters being condemned to a fifth straight defeat.
Bolton almost shocked Chelsea in the 22nd minute when Vaz Te worked a neat interchange with Jared Borgetti but his close-range effort struck the post, with keeper Petr Cech well beaten.
Chelsea had been unimpressive and Kevin Nolan was uncharacteristically off-target when presented with an opening 13 minutes before half-time.
But Chelsea were back on course for the title when they took the lead seconds before the break.
Lampard's whipped-in free-kick set up an aerial chance for both Terry and Didier Drogba, with the Chelsea skipper providing the final touch.
Both players claimed the goal but it was officially credited to Terry.
Henrik Pedersen's shot on the turn gave Chelsea an anxious moment - but Lampard sealed the points in trademark fashion after 58 minutes.
Lampard started the move with a pass to Crespo before timing his run into the box perfectly to receive the return ball and fire high past Jussi Jaaskelainen.
Chelsea substitute Arjen Robben then had a chance when he was set up by Drogba but his first touch was poor and Jaaskelainen made the interception.
Bolton's misery was complete when Ben Haim received a second yellow card for a needless foul on Michael Essien and was sent off by referee Phil Dowd.
Chelsea boss Jose Mourinho:
"I am very confident but we are not jumping, we are not singing, and neither are the players.
"It is now about the next game and we need four points from four matches."
Mourinho again hailed goal-scoring captain saying: "John Terry is the best in the world in his position and he has a great attitude."
Bolton boss Sam Allardyce:
"We fail to take our chances then the opposition get a goal before half-time.
"To play against Chelsea when you are 1-0 down is difficult.
"You cannot defend against the free-kick that led to their first goal."
