Chelsea edged a five-goal full-blooded London derby, surviving a late scare to return to the top of the WSL with a 3-2 win.
The title holders retained their unbeaten run, which now stands at 11 games, thanks to goals from Jess Carter, Lauren James and Guro Reiten. But the Blues were far from their fluent best, with Spurs making it a much closer contest than either of the previous meetings between the two London rivals this season.
Despite Carter's early goal for the visitors, Tottenham refused to buckle and made it hard for the champions to play through them. Ash Neville then capitalised on Kadeisha Buchanan's error to give Beth England a simple goal against her former club to level things up.
