Arsenal showed their title credentials by holding reigning champions Manchester City to a 0-0 draw on Sunday at the Etihad Stadium, allowing Liverpool to take top spot on a pivotal day in the Premier League's three-way title race.
Mikel Arteta's Arsenal, in the hunt for their first league title in 20 years, are second in the table on 65 points with nine games remaining, while City are third with 64.
Liverpool claimed the lead with their 2-1 comeback victory over Brighton & Hove Albion earlier in the day.
City dominated possession, coming at Arsenal in waves. But the visitors frustrated Pep Guardiola's men - including league-leading scorer Erling Haaland - with a textbook defensive display to extend their unbeaten league run to nine games.
Gabriel Jesus had Arsenal's best chances, firing two shots just wide in the first half and then narrowly failing to meet an inviting cross from Bukayo Saka.
City's best opportunity was Kevin De Bruyne's early corner kick that glanced off the shoulder of Nathan Ake but fell to keeper David Raya.
Striker Mohamed Salah scored the winner as Liverpool came back from a goal down to beat Brighton.
The Egyptian striker tormented Brighton, taking 12 shots to notch up his highest total in a Premier League game and, even though only one of them found the back of the net, it was to prove vital.
Danny Welbeck gave Brighton the lead after 84 seconds when his side broke up a Liverpool attack and burst forward to find him just inside the box and he drilled an unstoppable shot past Caoimhin Kelleher to break the deadlock.
The early goal jolted Liverpool into life and Luis Diaz put them level in the 27th minute after Joel Veltman's attempted clearance went awry, allowing the Colombian winger to steal in behind the defence and hook the ball home.
Liverpool's suffocating pressure and incisive attacking paid dividends again when Alexis Mac Allister teed up Salah to fire them into the lead.
