Leandro Trossard played a starring role as Premier League leaders Arsenal restored their five-point lead at the summit with a 3-0 victory over Fulham.
The Belgium international claimed a hat-trick of assists at Craven Cottage, with Gabriel Magalhaes, Gabriel Martinelli and Martin Odegaard all profiting.
Mikel Arteta's side subsequently became the first side in the history of English league football to win five successive away London derbies without conceding a single goal.
Arsenal, who welcomed Gabriel Jesus back from injury, also made it five straight Premier League victories in all as they took another step towards the title.
The Gunners thought they had taken the lead when Antonee Robinson put through his own net in the 16th minute, but the VAR ruled Martinelli had strayed offside before Bernd Leno parried his shot against the Fulham defender.
However, Arsenal broke through five minutes later as Gabriel, who scored the winner in the reverse fixture in August, climbed to head in Trossard's corner.
Trossard was the provider again when his cross was nodded in by Martinelli at the far post after 26 minutes, while Odegaard tucked away another precise centre from the former Brighton and Hove Albion man in first-half stoppage time.
Fulham were far more positive after the break. Bobby De Cordova-Reid drew a smart reflex save from Aaron Ramsdale, while Aleksandar Mitrovic's header hit the crossbar.
But Arsenal stood firm to deny their opponents a potential route back into the contest and went close to increasing their margin of victory through Odegaard and the returning Jesus.
Leeds United close Elland Road after security threat
Leeds United closed their Elland Road stadium "until further notice" on Friday following a security threat.
A threat was made on Thursday, reportedly on social media, leading to action being taken by the Premier League club.
A statement from Leeds read: "Leeds United's offices, ticket office, Foundation offices and club shop at Elland Road will be closed until further notice on the advice of the police.
"We apologise for any inconvenience and we will inform the public when normal service resumes."
A West Yorkshire Police statement added: "Police were called to attend at Elland Road football stadium following reports of a security threat to the premises.
"Investigations are currently ongoing to establish the credibility of that threat. The report was received at 9.49pm last night."
'Clubs are starting to call' – Argentina and Brighton star Mac Allister in demand
Argentina midfielder Alexis Mac Allister is drawing enquiries from a number of clubs that could bid for the World Cup winner, his father has revealed.
The 24-year-old has become a key player for Premier League side Brighton and Hove Albion, and he has been recently linked with the likes of Manchester City and Liverpool.
Playing a prominent role in Argentina's Qatar 2022 triumph has raised Mac Allister's profile, and his market value.
Brighton would be reluctant to see him leave, but Carlos Mac Allister, who was also capped by Argentina, says his son is wanted elsewhere.
"The clubs are starting to call us about Alexis, but there are no concrete conversations for now," he said, quoted by TNT Sports.
"We will decide together with Brighton, they deserve respect. We will also choose the best project based on the coach, it is not just about money."
Alexis Mac Allister, who has a contract through to the end of the 2024-25 season, recently said his "next step" should be with another Premier League club.
Liverpool may be looking to refresh their midfield at the end of the campaign, while Mac Allister could also be a shrewd replacement for Ilkay Gundogan should the Germany international leave City.
Brighton sit seventh in the Premier League and are firmly in the hunt for a European place, with Mac Allister netting seven goals and adding one assist during their success so far this term in that competition.
They are also through to the FA Cup semi-finals, where Manchester United await them at Wembley.
If Mac Allister stays in England, he would want to play for an elite team.
Mac Allister told TyC Sports, as reported on March 1: "I don't have a particular team where I say 'this is the way I play'. I think that here in the Premier League, there are very strong teams that play very well, like Manchester City and Arsenal.
"Chelsea too, I had [Graham] Potter as coach [at Brighton] and I know the idea he has of playing football.
"Manchester United are returning to be what they were, and Liverpool are going through some ups and downs but they still have a very important team.
"If I have to say a place, I would like my next step to be in the Premier League. But the truth is that I am very focused here in Brighton and enjoying the present."
Australia 3-1 Ecuador: Irvine, Mabil and Kuol lead Socceroos to victory
Jackson Irvine, Awer Mabil and Garang Kuol fired Australia to a 3-1 victory against Ecuador at the CommBank Stadium on Friday.
In their first game since the World Cup in Qatar, Australia's preparations for the Asian Cup got off to an ideal start.
First-half goals from Jackson and Mabil came either side of Felix Torres' equaliser in an action-packed opening period.
A much quieter second half saw few opportunities before 18-year-old Kuol scored his first senior international goal, ensuring there would be no late fightback from the South American side.
The hosts took the lead after 13 minutes, Mitchell Duke brilliantly volleying Craig Goodwin's free-kick back across the face of goal to Irvine, who converted into the empty net – though replays showed Duke should have been flagged for offside.
Ecuador responded quickly to the setback and, having seen Michael Estrada drag a glorious chance wide of the mark, levelled when Torres met Jeremy Sarmiento's cross and guided a header past Mathew Ryan.
Australia regained the lead in the 32nd minute, with Irvine dispossessing Piero Hincapie on the edge of the area and seeing the ball fall kindly for Mabil, who smashed a fierce strike into the top-right corner.
Manchester City's Alex Robertson made his debut in the second half, despite having yet to make a senior appearance for the Premier League side, following in the footsteps of his father and grandfather in featuring for the Socceroos.
There were few opportunities in the second half, but Moises Ramirez clawed an effort from Kye Rowles off the line, with Goodwin's set-piece delivery again causing problems for the visitors.
Though Ecuador dominated possession for much of the latter exchanges, the South Americans were unable to create opportunities to test Ryan and the hosts held on to secure victory.
The win was secured in the 84th minute, with teenage substitute Kuol on hand to poke in Aziz Behich's driven cross.
