Alexia Putellas scored a double in a statement win over London rivals Tottenham Hotspur, helping London City take a place in the WSL's top three.
The two-time Ballon d'Or winner opened the scoring from a rebound in the third minute, then doubled her tally in the 34th minute with a rocket from the edge of the box.
Kadidiatou Diani scored her first goals for London City, while Danielle van de Donk added to her tally after setting up Putellas' second.
Tottenham fought back through top scorer Victoria Pelova, but it wasn't enough to topple their London neighbours.
Diani made it hurt when she capitalised on a mistake by Lize Kop at the back in the 74th minute, calmly walking the ball over the line for London City's fifth.
Delphine Cascarino made it six in the fourth minute of injury time to round off London City Lionesses' dominant display in North London.
As it happened
The first goal came in the third minute, when Putellas pounced on the rebound from Grace Geyoro's shot from just outside the box. Spurs keeper and Netherlands international Lize Kop managed to push away Geyoro's long-range effort, but it fell straight into the path of the two-time Ballon d'Or winner Alexia Putellas, who made no mistake in front of goal.
Spurs struggled to hold onto possession as London City fought for every loose ball. Diani slid the ball into the back of the net from a whipped cross by Lucia Corrales in the 22nd minute to double the visitors' lead.
It felt too easy for the away side as Putellas hammered in her second 12 minutes later, after Danielle Van de Donk controlled the corner and squared it to her at the back of the box.
Van de Donk turned from provider to goalscorer when she swung in Diani's ball to claim London City's fourth in the 52nd minute.
Spurs had a brief respite when Victoria Pelova struck back only a minute later, which lifted their spirits. They created two close chances in the next ten minutes, with Cathinka Tandberg diving to meet Olivia Holdt's cross which fell just outside the goal.
