Arsenal are now 14 games unbeaten in the league and have 50 points from 24 games with leaders Liverpool on 56 from 23. Manchester City are a distant fourth with 41.
Arsenal kept alive their Premier League title challenge with a 5-1 demolition of Manchester City on Sunday (Feb 2) as the troubled champions endured another humiliation in their season from hell.
Mikel Arteta's side had no margin for error in the title race after leaders Liverpool won 2-0 at Bournemouth on Saturday to move nine points clear of the Gunners.
They rose to the occasion with a blistering performance inspired by Martin Odegaard's opener after 103 seconds at the Emirates Stadium.
Erling Haaland hauled Man City level soon after half-time with his 25th goal in all competitions this season. But the careless mistakes that have hampered City throughout a dismal campaign proved decisive when Thomas Partey capitalised on Phil Foden's poor pass to restore Arsenal's lead.
Myles Lewis-Skelly's first Arsenal goal and late strikes from Kai Havertz and Ethan Nwaneri put the seal on a masterful display as the Gunners closed within six points of Liverpool.
Liverpool's game in hand keeps them firmly in control of the title race, but Arsenal's vibrant performance extended their unbeaten run to 14 games and underlined their desire to push the Reds to the finish line.
Man City have now failed to win any of their last four league meetings with Arsenal as their six-game undefeated run in the top-flight came to a brutal end.
With a fifth successive title long erased from City's ambitions after their wretched season, Pep Guardiola's fourth placed side are focused on qualifying for the Champions League.
But even that could be beyond them – let alone getting past Real Madrid in this season's play-off round – unless Guardiola can fix the gaping holes in his defence and the lack of energy in midfield.
Guardiola had opted to bring in John Stones for former Lens defender Abdukodir Khusanov, who endured an error-strewn debut against Chelsea last weekend. But Stones was involved in the calamitous defending that gifted Arsenal the lead in the second minute.
It was Stones' pass to the marked Manuel Akanji that put his fellow defender in a difficult situation. Akanji was immediately robbed by Leandro Trossard before Kai Havertz picked out Odegaard and the Arsenal captain slotted home from 10 yards with City's defence in disarray.
