Chelsea throw on a couple of subs, Ji So-yun and Sam Kerr are off as Erin Cuthbert and Beth England come on.

Chelsea are surely not going to come back from this scenario.

Chelsea again get a chance but Pernille Harder can't volley the ball cleanly and a couple of efforts for Sam Kerr and Fran Kirby pass by.

Barcelona have brought on Asisat Oshoala and skipper Vicky Losada too, taking the armband from Alexia Putellas, who has served her side well.

Jess Carter makes a sliding challenge on Mariona Caldentey as she bundles toward the box, and times it brilliantly to curtail the attack.

Carter has had her hands full tonight.

Okay so you're 4-0 down, you're chasing a goal but you cannot neglect the basics on a set piece.

Jenni Hermoso gets a free header from a corner but can't guide it on target. It drifts away for a goal kick.

Chelsea get a free-kick down the other end following a crude challenge...

Great ball in from Guro Reiten, and Pernille Harder meets it but it's tamely into the palms of Sandra Panos.

That was a chance.

Jenni Hermoso gets away into the Chelsea box, but rather fatiguedly smacks the shot into the side-netting.

Maybe the first-half flurry is taking its toll.

Barca almost down to walking pace in attack.

Sophie Ingle, whose passing range has helped lift Chelsea in the second half, gets caught in possession but the Blues win it back.

Again the ball is pumped into the Barcelona box but the clearance just won't run for a blue shirt and the trailing Chelsea side are thwarted.

Caroline Graham Hansen's work is done, with a first-half goal, and she is replaced by Mariona Caldentey.

She's a real threat.

Loping run down the left from Caroline Graham Hansen and again she gets a cross in but it's beaten away and smothered by Ann-Katrin Berger.

Key take and a warning to Chelsea that Barcelona are still alert and alive.

There's positivity all over the pitch now. But they haven't got that early goal in the second half which they needed.

So close for Chelsea.

The Blues moved the ball around the box trying to fashion a gap, and Sophie Ingle found it with a razor-sharp pass to pick out Fran Kirby on the right side of the area.

Her cross whistles across before a flag goes up.

Then Kirby robs her opponent and breaks again but can't find the killer pass.

Pernille Harder has been a bit too quiet for me, she's the one with the experience. I want a bit more from her.

Chelsea almost slip the ball in behind as Ji looks for Pernille Harder. Barcelona get that little foot in that counts.

The Blues look to unlock a defence though which has blanketed the Barca box pretty much all evening.

Whatever's been said at half-time has worked so far.

They have a bit more natural width on the field.

There has definitely been some flow of traffic into the Barcelona box now.

Plenty of crosses into the box, asking some questions of the defence.

Sam Kerr is set away down the left but Barcelona flood back to cover.

They do keep getting there when needed, you have to say.

Fran Kirby gets a sniff of a chance in the Barcelona box but the pink shirts outnumber and get a crucial block.

This is much more of a display of intent from Chelsea.

Sam Kerr tries to peel away from her marker to meet Niamh Charles' cross but the ball sails just over her head and away to safety.

Sophie Ingle pings a pass to the right to release Niamh Charles, and her stinging low cross is stabbed behind by the Barcelona defence.

The Blues then force another corner.

Pernille Harder tries to turn the ball on goal, but it's blocked. Chelsea recycle.

The ball goes into the box and as Magda Eriksson goes down, but Riem Hussein the referee blows for a Barca free-kick.

Not too dissimilar to the Barca penalty.

Sam Kerr gets ahead of her marker and guides a header to the far post, but Sandra Panos scrambles to dive and save it.

Fran Kirby banged a ball into the box and Kerr got to it. It's a combination Chelsea need to rely on for a fightback.

Chelsea haven't got a grip when they needed to.

Pernille Harder's chance at 1-0 was so key, if she finishes that it's a completely different game.

Chelsea haven't done enough in this game. It's the Champions League final.

I'd love to know what Emma Hayes said at half-time because there needs to be a response here.
