West Ham claimed their first London derby away win over Tottenham Hotspur and a fifth league win of the season with a 2-0 victory at Brisbane Road as second-half goals from Dagny Brynjarsdóttir and Hawa Cissoko secured the points.
It was a classic Jekyll and Hyde performance from the Irons, whose impressive second-half display fired them to fifth in the WSL and just four points behind fourth-placed Manchester City before the winter break.
Despite a first-half penalty miss from Brynjarsdóttir, the Irons flipped the script in the second half, with the Iceland international making good on a loose ball three minutes into the half and after some obdurate defending, Cissoko's sublime chip over keeper Rebecca Spencer in the 85th minute sent the travelling West Ham contingent into a frenzy to cap off a clinical half.
