Chelsea have done the business. West Ham need a 15 minutes for the ages to turn the tide now.

A quarter of an hour into this one and it's Moneyfields who have enjoyed the best of the chances.

For all their calm possession London City Lionesses are yet to test debutant Rose Kite in the visitors' goal, which will disappoint head coach Carolina Morace.

Leicester have been making all of the early running in Derbyshire, as you'd expect, but Lena Petermann was just run out of space at the end of a fine run.

WSL side Tottenham find themselves 2-0 down at the start of the second half and are in danger of going out in the fourth round.

Former Manchester United and Leicester City striker Jess Sigsworth doubled the Blades' advantage. Ashley Hodson nutmegged here defender and curled a shot onto the post, with Sigsworth heading in on the rebound.

A massive task for Tottenham now..

It would be hard to deny that Chelsea deserve that lead. The winners of the last three FA Cups are now on track to progress.

Close!

Moneyfields winger Kimberley Fuller looks to swing a left footed cross into the box and as it drifts towards goal London City stopper Hermione Cull is forced to palm the ball onto the cross bar.

London City are just starting to gain the advantage in this one, at least in terms of possession. They're starting to knit together some passes and look a threat going forward.

Moneyfields seem content to let them keep the ball and hit on the break, that has proved rather effective so far.

First chance of the game and it does indeed go to the visitors Moneyfields.

A cross in from the right hand side picks out Kau'inohea Taylor in the six yard box but she can only direct her header wide of the target.

The holders are looking strong with West Ham looking tired. A corner reaches Nathalie Bjorn, who loops a header up onto the roof of the net.

Fourth tier Moneyfields Women overcame Gloucester City, Ashford Town (Middx), Haringey Borough and Millwall Lionesses before Christmas to book this FA Cup fourth round trip to Championship club London City Lionesses.

Coach Hannah Humphreys has insisted that despite the difference in league positions between the sides, Moneys will not be heading to Kent to make up the numbers.

They are certainly not being shy in these opening stages, really taking the game to their hosts.

The final whistle has gone at Barton Rovers and Brighton are through to the fifth round after a commanding victory over Luton.

Fifth tier Luton showed plenty of spirit, especially in the opening 20 minutes of the game, but the WSL class of the Seagulls ultimately shone through.

Liverpool have booked their place into the fifth round with a 1-0 victory away at fellow WSL side Bristol City.

In what started as a rather nervy encounter, Matt Beard's Reds were reduced to 10 on the hour mark when Ceri Holland was shown a second yellow card.

Despite the numerical disadvantage, Liverpool were victorious, but left it late to seal victory, with Gemma Bonner getting the winner with five minutes to spare.

An end to end opening to this one as both sides look to start on the front foot.

Both sides seeing plenty of the ball but neither is yet to have settled in possession as of yet.

Lauren James has been frustrating so far today but she looks as likely as anyone to put Chelsea ahead, arriving on to a cross at the far post but seeing her shot charged down.

Under way in both 3pm kick offs.

Can we get a giant killing in either tie with Moneyfields or Derby County getting a victory? Stay tuned to find out!

The extra time is go! Will the holders come through?
