The players are out in the French sunshine and captains Wendie Renard and Karen Carney exchange momentos.

Time for one last huddle, before kick-off.

Wales international Jess Fishlock, who is on loan at the Stade de Lyon-based outfit from American side Seattle Reign, said earlier this week: "We have to make sure we play well on the night.

"But I believe if we play to our highest level then we're a very difficult team to beat.

"The girls are so good and so experienced they can cope with the pressure of having to win again.

"I've come to Lyon to win a Champions League. That's what everyone wants to do here and we are confident that we can do it."

This match is being played at the same ground that will host this summer's Women's World Cup final.

Chelsea make just one change from the side that narrowly lost at Man City in the Women's FA Cup semi-finals last Sunday, as South Korea's Ji So-Yun swaps in for midfielder Drew Spence, who is on the bench.

Hosts Lyon give starts to England right-back Lucy Bronze and Wales midfielder Jess Fishlock, but England's Izzy Christiansen is out injured.

Lyon XI: Bouhaddi, Bronze, Mbock Barthy, Renard, Bacha, Henry, Fishlock, Cascarino, Marozsan, Le Sommer, Hegerberg.

Subs: Weiss, Kumagai, Majri, Van de Sanden, Buchanan, Jaimes, Simon.

Chelsea XI: Berger, Bright, Ingle, Carney, Ji, Kirby, Eriksson, Mjelde, Andersson, Cuthbert, Bachmann.

Subs: Lindahl, Thorisdottir, Blundell, Carter, England, Engman, Spence.

French giants Lyon have reached seven Women's Champions League finals since 2010, winning five.

The French side are aiming to win the competition for a fourth consecutive year and are the favourites again.

But Chelsea are in their second semi-final, having been knocked out by Wolfsburg in each of the past three campaigns, and at this stage last season.

But the German side can't oust Chelsea this term, because Lyon have already eliminated them.

Good afternoon! What an occasion we're about to witness today.

Chelsea are just 180 minutes away from reaching their first Women's Champions League final.

Standing in their way? Well, it's only the holders and five-time winners, Lyon!

Arsenal go four points clear at the top, with two games to go. The league is in their hands.

They'll lift the title if they win at Brighton next Sunday.

If not, they'll face second-placed Man City on the final day of the season...

Job done for Arsenal. They need just one more win to seal the WSL title!

"Everton are getting some moments now in the final third, late on in the game."

This would be a 16th league win of the season for Arsenal, in their 18th game.

They've not drawn yet this term, which is one of the main reasons why they're set to go four points clear.

Everton can only hit the roof of the net from a looping corner, as Arsenal edge closer and closer to victory.

We're in to the final minute of normal time now and Arsenal are closing in on what would be a vital win in their push for the title.

Off goes goalscorer Vivianne Miedema, as German forward Tabea Kemme comes on.

Abbey-Leigh Stringer is the latest Everton player to go off, as Olivia Chance comes on for the closing stages.

Emma Brownlie comes on for Everton, as Simone Magill gets a well-earned rest.

Everton will be really encouraged by their display here, but it won't count for much unless they can somehow find a second goal in the remaining seven minutes or so.

Arsenal bring on Danielle Carter in place of Katrine Veje, while Austria's Viktoria Schnaderbeck comes on for Beth Mead.
