Vicky Lopez comes on for Barcelona, replacing Ewa Pajor.

Maika Hamano is on for Chelsea in place of Johanna Rytting Kaneryd.

Alexia Putellas is determined to get on the scoresheet.

Fridolina Rolfo picks her out from the left but the skipper blazes over.

Into the final 20 minutes of Chelsea's Women's Champions League campaign.

The attendance has just been announced.

There are 26,702 inside Stamford Bridge.

Around 200 of them - who have come all the way over from Catalonia - will be going home very happy.

It's a little bit casual from Barcelona and Aggie Beever-Jones successfully battles to win the ball back in the box.

Chelsea have a corner but Sjoeke Nusken's header is no trouble for Cata Coll. Aside from one save, again from Nusken, in the first half, Coll has had very little to do.

A great opportunity for Chelsea to pull one back but substitute Catarina Macario fires wide of the far post.

Was she offside? It doesn't really matter.

Mary Earps has so much experience at major tournaments, but for me her presence is probably the differentiator. The way she can command her area, take a cross, the way the backline play with such confidence when she is behind them.

If I had to nit-pick, that is probably the thing that Hampton is missing, but it is so neck and neck.

Chelsea are nearly undone again, this time by a ball straight down the middle.

Ewa Pajor finds herself one on one with Hannah Hampton but the Chelsea keeper stands tall.

Another flurry of substitutions. A double change for Chelsea, with Sandy Baltimore and Erin Cuthbert making way for Wieke Kaptein and Catarina Macario.

For Barcelona, Salma Paralluelo, Jana Fernandez, and Esmee Brugts replace Claudia Pina, Irene Paredes, and Caroline Graham Hansen.

Alexia Putellas fires wide. Should she have passed the ball to the player on her left?

You can't blame her for wanting to get in on the goal-scoring fun. I make it 43 for Barcelona in the Champions League this season, for those keeping count.

Sandy Baltimore has a crack at goal from inside the box but the angle was always closing and she can only find the side netting.

Moments later, Sjoeke Nusken goes for goal from the edge of the box but instead converts the ball over the bar.

Aggie Beever-Jones goes down in the Barcelona area and gives a hopeful look to the referee.

She's unmoved. Goal-kick.

Another busy stint for Sandy Baltimore on the left.

Her first cross into the box is blocked almost before the ball has left her foot but she wins it back and fires in a second.

Alas, there's no one there. Story of the afternoon for Chelsea.

Ooooh that could've been four.

Fridolina Rolfo hits it first time from the edge of the box with her left foot but her shot is always rising.

It's amazing how quickly they move the ball and swarm the opposition when they're attacking.

A sedate start to the second half compared to the flurry of action at the end of the first. Little to report.

There's also been a half-time change for Barcelona, with Mapi Leon replaced by Ingrid Engen.
