Charlton have come out the blocks firing this afternoon, they’re giving Chelsea a tough game here. Karin Muya with two early chances pouncing on the counterattack. Charlton striker Ellie Brazil up top looks like she’s got a lot of energy going hot on the press. They’re hoping for an FA Cup upset and if they carry on with this flare, they just might achieve that!

A brief stoppage as Jessica Gray goes down for Charlton Athletic.

The goalkeeper receives treatment on her right leg after taking a goal kick but stays on the field for the time being.

Sophie Whitehouse is warming up on the sidelines.

Chelsea are beginning to click into gear and it's Lauren James who's at the heart of the action again, bringing a smart stop out of Jessica Gray with a long-range effort.

We are back underway for the second half in Edgware.

The Bees, who have their work cut out against the visitors, get us up and running again.

A good chance for Chelsea goes begging!

Lauren James goes passed Gracie Pearse on the right wing and fizzes a cross into the box, but there's no one to get on the end of it.

Much better from the Blues, who have looked a little rusty in these opening exchanges.

Good question.

There's no replays in the Women's FA Cup.

Now we're in the fourth round we go to extra time - in the usual 30-minute, with two 15-minute halves, format.

If a tie is still level then we go to penalties.

Up to and including the second round ties just go straight to penalties.

All square at Kayte Lane at the break, with home keeper Mia Smith making a couple of decent saves.

Karin Muya goes close for Charlton! She pounces on a loose ball in the box but hits her shot straight down Hannah Hampton's throat.

Chelsea will have to be on their toes.

A steady start from the two sides at Kingsmeadow, with goalkeepers Hannah Hampton and Jessica Gray both called into action in the opening five minutes.

Chelsea are looking busy down the left wing but Charlton have looked equally threatening on the counter.

Lauren James is on the ball early, finding the feet of Mayra Ramirez as Chelsea push forward.

James is making her first appearance for nearly three months after being sidelined with a calf injury.

Can Charlton become the first side to defeat Sonia Bompastor's Blues?

A ruthless display from Championship side Sunderland.

It is all over at Kingston Park, and Jasmine McQuade's excellent goal after 76 minutes is the difference that sees Forest bow out and Newcastle go through.

Not quite the 10-0 of a few years back but a comfortable win for Manchester City nonetheless.

Goals from Jill Roord, Laura Coombs and the returning Vivianne Mediema see them safely through to the fifth round.

Ipswich defended admirably, especially in the first half, but never really threatened the WSL contenders.

It's been as easy as it gets for third-tier Rugby here.

They already have one foot in the next round of the Women's FA Cup, thanks to goals from Nicola Potts, Ebony Wiseman, Mai Moncaster and Angelina Nixon.

The hosts will need a much-improved display after the restart to avoid a thumping here.

A statement of intent that Sonia Bompastor wants to get the job done today, as she names a first team line-up.

Four changes since their Champions League win over Real Madrid. Lauren James returns after three months out with injury. A front line of Cat Macario and Mayra Ramirez, and first FA Cup starts for Sandy Baltimore and Oriane Jean-Francois.

Charlton are hoping for a cup upset today against the unbeaten Women's Super League leaders. Two changes from Karen Hill after a draw at Birmingham City. Jessica Gray comes in between the sticks for Sophie Whitehouse and former West Ham midfielder Melisa Filis returns for Atlanta Primus.

With five minutes until kick-off at Kingsmeadow, let's look at the team news.

Sonia Bompastor has named a strong team for Chelsea's fourth round meeting with Charlton, with Lauren James returning to the starting XI.

James has been sidelined with a calf injury since late October and has been restricted to four appearances in all competitions this season.

Chelsea XI: Hampton, Bronze, Bright (C), Bjorn, Baltimore, Jean-Francois, Cuthbert, Reiten, James, Macario, Ramirez

Subs: Musovic, Nusken, Bernabe, Charles, Lawrence, Perisset, Kaptein, Hamano, Beever-Jones

Charlton Athletic XI: Gray, Pearse, Skeels (c), N’Dow, Newsham, Hutton, Filis, Bradley, Muya, Brazil, Barton

Subs: Whitehouse, Siber, Bashford, O'Rourke, Primus, Chime, Mitchell-Ramon

Charlton Athletic have endured a challenging first half to the season. After missing out on promotion to the WSL by a single point in 2023-24, they currently find themselves eighth in the Championship table and with just one win - a 4-0 victory over Lewes in the FA Cup third round - in their past 12 matches.

However, despite their poor form, defender Charlotte Newsham said her side are targeting an "FA Cup upset" against high-flying Chelsea.

The Blues are unbeaten in 16 matches in all competitions since Sonia Bompastor replaced Emma Hayes as head coach in July.

"If you're going to get a big team, you may as well go as big as you can get," said Newsham, speaking to BBC Radio London.

"It's the FA Cup and you want to play different teams to the ones you play every week. Chelsea is a big team but we've just got to go out there and cause an FA Cup upset if we can.

"The team's come on leaps and bounds and these are the teams you'd be playing in the WSL if you did get promoted. It's an exciting game for us."

Chelsea manager Sonia Bompastor emphasised the importance of maintaining momentum in their pursuit of silverware as they begin their FA Cup campaign.

For Chelsea, the FA Cup is not just another competition - it’s a prized target.

"We know how big the FA Cup is in England," Bompastor said. "It’s a trophy to win.

"I’ve heard a lot of good and positive things about the FA Cup in England. We feel ready for the game on Sunday. Ready to face an opposition who are prepared to give us a tough game. Charlton have good physicality."

The Blues will face a Charlton side determined to test their spirit, but Bompastor is confident her team is prepared.

"Cup games always demand a different mentality, and we’re ready to rise to the challenge," added Bompastor.
