Ella Toone's hat-trick helped Manchester United stun Manchester City 4-2 as they leapfrogged their neighbours in the table.

Toone had never found the net against City, but changed that in a barnstorming derby at the Etihad Stadium. Two first-half strikes by Toone, alongside Leah Galton’s 21st-minute tap-in, put the visitors in control amid an error-strewn City display.

Gareth Taylor’s side fought back before the break, however, through Vivianne Miedema and Rebecca Knaak.

It set up an intriguing second period, but Toone completed her treble a matter of seconds after the restart when City keeper Khiara Keating’s clearance was charged down.

Arsenal put five past relegation-threatened Crystal Palace in Renee Slegers’ first game since she was appointed permanent manager of the Gunners.

Leah Williamson got the scoring underway in the sixth minute before Beth Mead and a Mariona Caldentey brace, one of which was a penalty, ensured their boss’s unbeaten run since taking over from Jonas Eidevall in October was maintained.

Leaders Chelsea continued their imperious form by thumping West Ham 5-0.

Catarina Macario, Erin Cuthbert, Aggie Beever-Jones and Sandy Baltimore all fired superb efforts past goalkeeper Kinga Szemik, before Amber Tysiak’s late own goal helped the Blues pick up their biggest away win since September.

A fourth-minute own goal from Leicester goalkeeper Janina Leitzig was all Tottenham needed to pick up all three points and move past Liverpool into sixth place.
