Match ends, Chelsea 4, Morecambe 0.
Last season's FA Cup runners-up Chelsea returned to winning ways, comfortably beating League Two Morecambe to reach the fourth round on Sunday.
England midfielder Mason Mount put a strong Blues side ahead on his 22nd birthday from 25 yards.
Germany forward Timo Werner doubled the lead from close range - his first club goal since 7 November - before Callum Hudson-Odoi hit the third.
Kai Havertz headed the fourth after meeting Cesar Azpilicueta's cross.
Morecambe's Adam Phillips almost caught Kepa Arrizabalaga out at 0-0.
Phillips fired in a low cross which looked to have embarrassed the hosts keeper before he somehow recovered to save on the line.

Morecambe, making their first third-round appearance since 2003, equipped themselves well after recovering from a coronavirus outbreak at the club which denied captain Sam Lavelle a place in the side.
They only returned to training on Tuesday after coming out of isolation.
But Chelsea's quality proved too much for the Shrimps, who were playing their first match since 26 December.
Blues manager Frank Lampard will surely have been particularly pleased with his side's second goal on the way to a second win in eight Premier League and cup outings.
Werner was in the right place to end a run of 827 minutes without scoring for Chelsea after a headed assist by fellow Germany international Havertz, who has struggled to hit form since completing a £71m move from Bayer Leverkusen in September.
Morecambe paid tribute to their former defender Christian Mbulu, who died in May 2020, by displaying a framed picture of the player on the substitutes' bench at Stamford Bridge.
'Some of the greatest players need time'
Chelsea manager Lampard: "I'm pleased for Timo to score because strikers want to score goals - he's had a lot of near misses in that time.
"He'd been getting into positions to score goals but they hadn't been going in for him. With him and Kai coming into the Premier League, some of the greatest Premier League players have needed time to settle to the league.
"It's a nice little step for both of them."
Morecambe boss Derek Adams: "I've got to be proud of my players. When I looked at the team that Chelsea put out I wasn't too happy, but they showed a great deal of respect to the FA Cup so credit to them.
"We defended really well at times and kept our discipline and shape."
Chelsea are back in Premier League action on Friday when they make the short trip to west London rivals Fulham (20:00 GMT kick-off), while Morecambe have a League Two game at Leyton Orient on Saturday (15:00).
