Arsenal moved up to second in the Premier League after a rampant first-half performance propelled them to a 5-2 victory over West Ham United.
All of the goals came in a remarkable opening period at London Stadium, where Gabriel Magalhaes, Leandro Trossard, Martin Odegaard and Kai Havertz put Arsenal 4-0 up inside 36 minutes.
But quickfire strikes from Aaron Wan-Bissaka and Emerson gave West Ham hope, though their chances of a comeback were quashed when Bukayo Saka, who also provided two assists, added Arsenal's fifth on the stroke of half-time.
It is only the fourth time in Premier League history that there have been seven goals scored in a single half, but the Gunners put in a more measured display after the interval to ensure there was no hint of further drama.
Arsenal now sit six points behind leaders Liverpool, who face a heavyweight clash with Manchester City on Sunday, while West Ham remain in 14th.
