Arsenal reduced Liverpool’s lead at the top of the Premier League to two points after a deserved victory in a tense encounter at Emirates Stadium.
The Gunners knew defeat was unthinkable and their cause was helped hugely by Liverpool’s normally reliable keeper Alisson enduring a nightmare as two errors gifted Arsenal the goals that ensured three crucial points.
It sparked joyous scenes at the final whistle as Arsenal condemned Liverpool to only their second league defeat this season, their first since a highly controversial loss at Tottenham in late September.
Arsenal were rewarded for a lightning start when Bukayo Saka gave them a 14th-minute lead, turning home a rebound after Alisson saved from Kai Havertz.
The hosts were dominant but a defensive shambles allowed Liverpool to restore parity seconds before the break, Gabriel turning the ball into his own net via his hand after a mix-up between keeper David Raya and William Saliba as they challenged Luis Diaz.
