Sarah Mayling's cross into the box is just beyond the reach of Leicester substitute Ashleigh Neville.

It's all a bit tense with a place in next season's Women's Super League on offer for today's winners.

20 minutes of regulation time remaining at The Valley.

We’re entering that territory where heroes are made and names are written into the history books.

You are just waiting for one player to take the game by the scruff of the neck, create something and get some momentum going for their team.

Charlton make a change as Emma Bissell makes way for Amalie Thestrup.

It also provides the players with a chance for a quick drinks break midway through the second half.

A corner for Leicester is taken by captain Sam Tierney.

Sophie Whitehouse comes off her line to catch but lands heavily and hurt herself.

There are a few half-hearted appeals from the Foxes for a penalty after a challenge on Shannon O’Brien by Lucy Fitzgerald, but nothing given.

It feels like Leicester are finally managing to get a foothold now, managing to send a few crosses into the Charlton box.

But it leaves them more exposed to counterattacks, and Jodie Hutton takes advantage of one such break to win a throw-in at the other end.

The changes Leicester have made, they are three players I would have started. Williams, we know she loves a late goal, and Van Egmond is great with link up play. They want to push and gamble and the substitutions make that clear.

Some neat work from Shannon O'Brien to win a corner for Leicester.

The Foxes will hope to relieve some of this pressure with fresh legs on the field now.

Katie Bradley with another corner for Charlton.

It's an in-swinging one towards the near post but only finds the side-netting.

Leicester manager Rick Passmoor is already turning to his bench and it's a triple change for the Foxes only 10 minutes into the second half.

Ashleigh Neville, Emily van Egmond and Rachel Williams are coming on.

Asmita Ale, Hannah Cain and Jutta Rantala make way for the experienced trio.

Temperatures are touching 29C in London this afternoon.

Both sides will be keen to get the job done inside 90 minutes - avoiding the added test of extra time or penalties in these conditions.

Olivia McLoughlin is cautioned for a foul on Mary McAteer.

Moments later, Ellie Mason tires her luck from distance - almost trying to lift it over Leicester keeper Katie Keane - but doesn't get the execution right.

Back-to-back corners for Charlton now.

And Lucia Lobato goes close with a header but can't get it on target.

In fact, Charlton are yet to register a shot on target in the play-off.

Charlton on top right away.

Mary McAteer does well to bring a cross under control inside the box but is denied the space to get a shot away. They eventually win a corner out of it.

Back under way!

Will we find a winner in the next 45 minutes?

Leicester look reserved. I'd like to see more of Cain and O'Brien on the ball. We know that they have so much to offer on the ball in that front line going forward. They need to be braver in the way that they are playing.

It looks to me that Leicester are trying not to lose it while Charlton are trying to win it. This is a head to head game, dog eat dog, they just need to go for it.

Charlton are clever and hard to break down, they have won so many duels, and they are great without the ball.

They have changed their structure, meaning that they are always breaking with three or four, and they have made some good opportunities on the break. They have been the better side for me.
