There were five Matildas in action at one point in the West Ham-Arsenal Women's Super League derby — but only one who appeared to be everywhere.

It was Katrina Gorry who produced another tireless afternoon at the heart of the Hammers' midfield engine room, powering her side to a 2-1 victory, their first-ever over Arsenal in the WSL era.

The diminutive star's player of the match performance raised the question whether the signing of the 31-year-old Australian international might just have been the best piece of business in the entire WSL January transfer window.

'Mini' was snapped up by West Ham specifically for her fighting attitude and non-stop foraging at the heart of midfield, as West Ham attempted to avoid the drop.

And sure enough, her influence has led to a revival for Rehanne Skinner's team, who have now moved away from the danger zone with two straight wins.

This victory, though, was of a different gravy for West Ham, defeating title challengers Arsenal with three Matildas in their ranks — Caitlin Foord, Steph Catley and Kyra Cooney-Cross.

On the day England captain Leah Williamson made her first start in nine months after her ACL injury, it had looked straightforward for the Gunners when Arsenal went ahead just before the break.
