Ellie Mason is booked for pulling the shirt of Alexia Putellas centimetres outside the penalty area.

The Charlton defender had no choice there - Putellas had rounded her and was in.

London City goalkeeper Elene Lete gets away with one as she takes her time dealing with a back pass, but she just about manages to get the ball away with Gillian Kenney bearing down on her.

Elisha N'Dow tries to play her way out of the Charlton penalty area but gifts the ball to Poppy Pattinson.

The London City full-back whips in a cross but Kadidiatou Diani can't quite get her head to it.

London City Lionesses want to play with attacking mentality, they can get a bit messy. For Charlton, they need to decide when to attack.

London City defender Mapi Leon whips in a cross from the left and the ball falls to Grace Geyoro at the edge of the box, but she fires over off balance.

Charlton make a change.

Grace Johnston replaces Leighanne Robe, who was booked in the first half.

Charlton have done a good job of getting numbers behind the ball but they don't quite have the organisation in those moments and that's why they are being punished at this level.

Birmingham City will be very pleased to head into the break with only a one-goal deficit.

Saving a couple of half-chances at the other end, it has all been Chelsea so far. The hosts have had 14 shots, but only Lexi Potter could make hers count.

Will Birmingham continue to frustrate them in the second half? If so, they'll fancy themselves to nick something, as their neighbours Aston Villa did here on the opening weekend.

All to play for at Stamford Bridge.

It's fair to say the momentum was with London City for the vast majority of that first half.

A first shot of the game for Birmingham City and it goes to the player you'd want it to - Oceane Hurtre.

She hits it well from range, but it's a comfortbale catch for Chelsea goalkeeper Hannah Hampton.

London City had a good start to the game, they created a lot of opportunities and that early goal settled them a bit. They still looked vulnerable at times, especially in those transition moments.

Chelsea's Ellie Carpenter stings the hands of Sophie Baggaley.

It's the fourth save the Birmingham City goalkeeper has been forced to make.

That Jodie Hutton goal has certainly woken the Charlton fans up. They are going to need the fans to get through this.

You can see the impact it's had on the players as well. Notice how much higher up they are on the pitch. The frontline looks like it's found some new new energy.

Chelsea's Sjoeke Nusken strikes the cross bar with a powerful header.

It comes from a cross by Alyssa Thompson, who's had a cracking first half.

There are ten minutes until the break, and Chelsea manager Sonia Bompastor will want to see another goal for her side's efforts.

That'll do it for the first half at The Valley.

London City have dominated, but the main talking point is rightly Jodie Hutton's wondergoal for Charlton. What a hit that was.

However, unless she can do that a couple more times in the second half, it's hard to see how Charlton get back in this game.

Admittedly few and far between, but there are promising signs for Birmingham City Amy Merricks.

The visitors put together a nice string of passes and find Marie Levasseur up by the corner flag in Chelsea's defensive third.

But Sandy Baltimore bullies her off the ball before she can do anything threatening with it.
