Kadeisha Buchanan does well to keep hold of the ball and drives forward towards goal. She plays a tempting ball across the edge of the area but there's no one there to pick it up.

It eventually comes out to Erin Cuthbert, who goes for it from range but it sails over into the stand.

Ann-Katrin Berger collects a free-kick and immediately throws it out to Rytting Kaneryd who sprints forward to try and get something on the counter. She's pushed out wide and the attack dies down eventually.

But that's what fresh legs will do for you.

Chelsea make a fast start as Sam Kerr looks to get forward early doors.

At the other end, Lindsey Horan pops one off from distance but it goes wide.

Here we go. 30 minutes to sort this out or we're off to penalties.

Chelsea make a change as Guro Reiten comes off for Rytting Kaneryd.

Well it's been a fascinating contest. I imagine there'll be some tired legs out there now as both sides were really going for it in those final minutes.

Who can hold their nerve?

Both teams, full credit to them. They’ve really gave it a go in these last 10 minutes.

They’re not sitting back and playing for extra-time. They want to win.

It's been a brilliant game. They've laid everything out there.

We've got another half an hour of this! It's been a brilliant game. Can't call who will win but Chelsea's bench is thin and they were starting to tire a little towards the end of normal time.

Well that's it. To extra time we go.

Huge chance for Lyon to take it in the dying seconds.

The cross comes in and Magdalena Eriksson gets a crucial header on it to turn it behind.

Corner to Lyon but cleared again. Time is basically up.

Delphine Cascarino charges off down the left-hand side and looks to whip in a cross but Magdalena Eriksson clears.

There are some tired legs out there, now, as both sides have gone full throttle in the last 10 -15 minutes looking for a goal.

Danielle van de Donk shoves Guro Reiten off the ball. Vicky Becho receives it out wide on the right and goes for a similar cross as the one that provided the goal, but this time it goes behind for a goal kick.

Three minutes to go.

Lindsey Horan sends in a sweeping ball, looking for Ada Hegerberg, but it's cleared by a blue shirt.

Lyon will just look to use their experience here. They're pinging balls in from every angle looking to try and get a goal.

Lyon look more likely to score at the moment. Emma Hayes is waving her arms around frustratingly.

We'll have seven massive minutes added on.

This is wave after wave now at both ends as each side look for a winner and try to prevent this from going to extra time.

Two minutes plus added time to make something happen.

It was there for Chelsea. Lyon had switched off.

What a tantalising cross from Lauren James. Sam Kerr was just inches away at the back post.

That would have been fantastic.

Ahhhhh.

Chelsea take a quick free-kick and Lauren James curls a low ball round to Sam Kerr but it's just a bit too deep for the Australian forward.

Right idea. Who can hold their nerve, here?

Emma Sanders

I'm stressed. This is stressful. And very exciting!

Lauren James gets away down the left-hand side but Danielle van de Donk puts in a frustrated tackle and she's in the book for it.

Maren Mjelde whips in the delivery but it's headed away by Wendie Renard.

The tempo has just been upped in these last few minutes.
