Chelsea manager Emma Hayes was left feeling “mentally drained” after her “amazing” team battled back to clinch a third consecutive Barclays Women’s Super League title.

The Blues twice came from behind to beat Manchester United 4-2 and hold off the challenge of second-placed Arsenal.

Goals from Erin Cuthbert and Guro Reiten, either side of a pair of stunning volleys from Sam Kerr, did the damage at a sold-out Kingsmeadow.

“First half I thought we played with fear; second half we played to win and I have to credit the whole dressing room for switching that mentality because we knew we had something to lose,” Hayes told her club’s website

“Once we play like we had something to win, that was the difference.

“We’re 2-1 down at home, packed house, everyone’s thinking, ‘oh no, you can’t lose the title at home’ and then we go and do that second half, we’re just amazing.”

Chelsea will look to complete the double in next Sunday’s FA Cup final against Manchester City.

“I’m absolutely mentally drained right now,” added Hayes. “I will just go home, have a cup of tea as usual and get ready for tomorrow.”

Arsenal knew they could snatch the title on the final day, if they bettered Chelsea’s result.

It looked within their reach when their rivals twice trailed the Red Devils, first following Martha Thomas’ header and again when Ella Toone volleyed home after Cuthbert briefly levelled.

But the Blues roared back in the second period. Kerr equalised and later gave her side breathing space with another fine strike following Reiten’s close-range finish.

Goalscorer Cuthbert said: “I feel like it’s the best one (title success) yet. The league’s getting tighter, more competitive, we’ve won it on the last day.

“Probably everyone was watching thinking we were down and out but never write off this team.

“We’ve got a top mentality, a top manager – what a day for the football club.”

Jonas Eidevall’s Gunners did everything they could, securing a 2-0 win away to West Ham thanks to second-half goals from Stina Blackstenius and Vivianne Miedema, but it proved to be in vain.

Miedema’s future with the Gunners is uncertain, with the Dutch star out of contract this summer.

The Hammers confirmed after the match that Paul Konchesky was replacing Olli Harder as manager, the latter having informed the club of his desire to “pursue new opportunities”.

Former West Ham defender Konchesky, who has worked as Harder’s assistant for the past 12 months, has agreed a two-year deal.

Manchester City clinched the third Champions League berth with a 4-0 victory over Reading.

At kick-off they knew that if they lost and local rivals Manchester United won they would be pipped for third place, but City were comfortable by half-time after goals from Lauren Hemp and Khadija Shaw.

An 85th-minute goal from Ellen White and an added-time penalty from Alex Greenwood made the result safe, and means City head into the cup final in fine form.

Tottenham consolidated fifth place with a 1-0 win over Leicester thanks to Ashleigh Neville’s goal early in the second half, while Brighton and Everton drew 1-1.

Nathalie Bjorn’s penalty in stoppage time gave the Toffees a half-time lead but it lasted just seven minutes after the restart when Aileen Whelan pulled Albion level.

Relegated Birmingham ended the season on a high with a 1-0 win over rivals Aston Villa.

Greek forward Veatriki Sarri netted the only goal in the 10th minute.
