Chelsea have moved three points clear atop the Premier League, after Manchester City lost 2-0 to Crystal Palace and Liverpool drew 2-2 with Brighton & Hove Albion.
Thomas Tuchel's Chelsea coasted to a 3-0 win at struggling Newcastle United, with Reece James scoring twice, before a Jorginho penalty wrapped up the victory.
The West London club have 25 points from 10 games, with Liverpool three points behind and champions City two further back.
Tuchel is pleased with the patience his team showed in a goalless first half, but refuses to celebrate the points dropped by their title rivals.
"It is a good day because of us," he says. "I believe what goes around comes around, and I don't feel happy to celebrate other performances and results.
"We should be focused on ourselves. There is a long way to go and we know what we consistently need to produce to be able to have results."
City fell behind to a Wilfried Zaha goal in the sixth minute and had defender Aymeric Laporte sent off for denying Zaha a goalscoring opportunity on the stroke of halftime.
Gabriel Jesus had an effort for City disallowed for offside by video review, before Conor Gallagher secured the surprise victory for Palace.
"We need to do everything right, but the players showed character," says City manager Pep Guardiola. "Unfortunately, it went wrong in many, many things."
On a high after their 5-0 thrashing of Manchester United last Sunday, Liverpool were brought back down to earth by Brighton at Anfield.
Jordan Henderson and Sadio Mane put Juergen Klopp's side in control, but Zambian midfielder Enock Mwepu brought Brighton back into the game with a delightful long-range effort that sailed over Liverpool goalkeeper Alisson Becker.
Brighton gained the upper hand after the break and drew level in the 65th minute, when Leandro Trossard sidestepped his marker and drove a low shot past Alisson.
Three goals were ruled out after video checks, Mane having one chalked off for handball and Salah another for offside, while Trossard's effort was also scrapped for offside.
"It feels like a defeat," says Liverpool manager Juergen Klopp. "It's not only because we were 2-0 up and didn't win, it's because the game I saw, we scored two of the most beautiful goals I've ever seen us score, which were disallowed.
"In the second half, we were not good enough. The body language I didn't like it all - it was like 'oh my God, it's really tough'."
Arsenal's good run of form continued with a 2-0 victory at Leicester City, thanks to goals from Gabriel and Emile Smith Rowe.
At the bottom end of the table, Burnley picked up their first win of the season with a 3-1 victory over promoted Brentford, with All White striker Chris Wood finding the net for the winners.
Meanwhile, Manchester United have thrashed Tottenham Hotspur 3-0, with goals from Cristiano Ronaldo, Edinson Cavani and Marcus Rashford to ease the pressure on manager Ole Gunnar Solskjaer.
Ronaldo struck in the 39th minute with a perfect right-foot volley into the far corner of Hugo Lloris's net from a glorious pass by Portuguese compatriot Bruno Fernandes.
Cavani added the second in the 64th and substitute Rashford wrapped up a comfortable win four minutes from time, as United put last weekend's drubbing by Liverpool behind them.
