Arsenal survived a late Tottenham comeback to move four points clear of Manchester City at the top of the Premier League.
It looked like it was going to be an easy afternoon for the Gunners, who raced into a 3-0 first half half lead, thanks to an own goal from Pierre-Emile Hojbjerg, Saka and a Kai Havertz header.
Cristian Romero pulled one back for Spurs following a howler from David Raya in the Arsenal goal, before Heung-Min Son scored a penalty in the 87th minute to set up a nervy finish.
