A Cristian Romero own goal gave Arsenal a deserved lead before Son Heung-min stunned the Emirates with an equaliser just before half-time.
The Gunners fired back after the break, with Bukayo Saka scoring from the spot after a controversial handball was awarded against Romero, but yet again Son silenced the home crowd by levelling the game again just seconds after the penalty kick.
Both sides came into the match in fantastic form, having won four and drawn one of their opening five Premier League fixtures, though Mikel Arteta found himself without both key forwards Gabriel Martinelli and Leandro Trossard.
Nevertheless, it was the home side that made the better start, with Guglielmo Vicario producing a fine save to deny Gabriel Jesus at the far past after he was set up by Saka’s delicious cross.
Saka was a threat all game long with Destiny Udogie struggling to contain him, and things nearly went from bad to worse for the young left-back getting booked for a rash foul and then just a minute later his wayward pass gifted Eddie Nketiah a golden opportunity to take the lead, but Vicario saved again.
Eventually, the deadlock was broken, and Saka was inevitably the architect, left with time and space on the edge of the box, the England star fired a hopeful shot at goal which kindly deflected off Romero and past a helpless Vicario.
