Teenager Reece James scored and set up two goals on his full debut as Chelsea thrashed League Two side Grimsby Town in the Carabao Cup third round.
James, 19, set up Michy Batshuayi in the seventh minute before his superb cross was tapped in by Kurt Zouma.
He added Chelsea’s fifth late in the second half before Batshuayi slotted home his second goal.
Chelsea’s Ross Barkley and Callum Hudson-Odoi also scored, while Grimsby’s Matt Green netted a volley.
The Blues take on Premier League rivals Manchester United in the next round after they scraped past League One side Rochdale in a penalty shootout.
It is the fourth successive season in which they face United in a cup competition.
Manager Frank Lampard changed the entire starting XI following Chelsea’s defeat by Premier League leaders Liverpool on Sunday, but there were several big names included.
Batshuayi has played just 32 minutes in the league this season and was on the scoresheet for the first time since January 2018.
He was joined in the starting line-up by £58m signing Christian Pulisic and 18-year-old England international Hudson-Odoi – the latter returning from an Achilles injury suffered in April.
But it was James who impressed the most – linking up with Batshuayi in the build-up to the second goal and setting up Zouma with a superb cross from the outside of his boot after the break.
Grimsby’s 32-year-old striker Green gave more than 5,000 travelling fans a glimpse of hope at Stamford Bridge as Chelsea were caught out by a long ball in the 19th minute, but from then on the hosts dominated.
Aside from an early volley from Elliott Whitehouse, Chelsea keeper Willy Caballero was barely troubled and the Blues recorded their 12th successive victory against a team from outside the Premier League in this competition.
A man found dead in north-west London was killed in a drive-by shooting, police said.
The 24-year-old man was found with a gunshot wound in Malden Road, Kentish Town, late on Sunday.
CCTV revealed two people on a moped had pulled up to the victim, pulled out a gun and fired at close range. The man died at the scene.
An eyewitness described how he tried to perform CPR on the man with the help of a 999 operator.
Will, who did not want to give his full name, said: “There were a number of people around him when I got down there, but nobody was doing anything.
“With the aid of the operator on the phone, I performed CPR. But I think he was already dead then.”
Officers said they were keen to trace people who had been in a Toyota Prius, a Ford Focus and a motorbike in the area at the time.
The man’s next of kin have been informed and post-mortem tests are due to be held on Tuesday, police said.
Det Ch Insp Simon Stancombe, from the Met Police, said: “Everything we have found out so far points to this being a drive-by shooting.”
He urged eyewitnesses or anyone with dashcam footage to contact the force.
The killing was the second fatal shooting in less than 12 hours in London.
A man in his 20s was shot dead in Sydenham, south-east London, on Sunday afternoon.
Swindon moved up to fourth in League Two following a well-deserved victory over Leyton Orient at Brisbane Road.
Keshi Anderson put the visitors ahead in the 23rd minute. The 24-year-old was fouled and sent his free-kick into the wall but reacted quickest to pounce on the loose ball and curl into the far corner past Dean Brill.
Richie Wellens’ men continued to maraud forward and their attacking intent paid dividends again two minutes before the break, with Rob Hunt’s audacious side-foot from the corner of the box taking a telling deflection off Orient left-back Joe Widdowson and flying past a surprised Brill.
The game was then over in first-half stoppage time when Lloyd Isgrove provided his sixth assist of the league season.
The former Southampton winger darted through the centre of the pitch before laying off to Jerry Yates, who cut onto his right foot before finishing with aplomb.
Jordan Maguire-Drew curled home brilliantly from 20 yards to give Orient hope with 16 minutes of normal time left but Swindon held on to send their fans home happy.
