Premier League leaders Arsenal survived a second-half scare at Tottenham to hold on for a 3-2 north London derby victory that cemented their place at the top.

A 23-minute first-half blitz saw the Gunners race into a 3-0 lead through a Pierre-Emile Hojbjerg headed own goal, Bukayo Saka finish and Kai Havertz header.

But with Arsenal in total control, a 64th-minute howler by goalkeeper David Raya allowed Cristian Romero to pull one back.

An 87th-minute Heung-Min Son penalty then set up a nervy finish for the Gunners, who withstood Spurs' late pressure to hold on to move four points clear of Manchester City and keep their hopes alive of a first Premier League title in 20 years.

Tottenham, meanwhile, suffered a second consecutive defeat to fall seven points behind fourth-placed Aston Villa in a further blow to their hopes of Champions League qualification.
