Every time Barca go on the attack, the crowd are roaring with anticipation. Chelsea are already starting to "suffer" as Emma Hayes predicted. Barcelona are getting more and more chances.

A moment's respite for Chelsea as the physios come on after a clash of heads at a Barcelona corner.

Fridolina Rolfo and Magdalena Eriksson are up again now, though, and able to continue.

You can just hear the atmosphere, the intensity, the speed of the play has gone up.

That's the third time now had Oshoala's end product been better, they could be in the lead here.

Chelsea are clinging on now. After Caroline Graham Hansen's shot is blocked, the ball comes to Asisat Oshoala but the striker fires the shot over the bar.

Big chance!

Let off for Chelsea after Caroline Graham Hansen puts the ball in the net but the referee blows for a handball.

It was a good ball in from the left, Magdalena Eriksson allowed it to bounce and Graham Hansen was able to bring it down and finish.

Fortunately for Chelsea, the first touch was with her arm.

Barcelona look to have settled after those early jitters and come forward again.

Caroline Graham Hansen puts a low cross in from the right but Chelsea clear.

That's a warning sign for Chelsea. When they commit and go and try and win the ball and they don't get it, they leave Oshoala in the transition.

Asisat Oshoala finds space again as Barcelona break. The striker gets to the edge of the box, the shot is on but she looks to feed the ball into the middle.

With no Barca players in there, that's a strange decision.

The volume inside the Nou Camp goes up a few notches as Barcelona come forward for the first time.

Asisat Oshoala gets into the box and gets into a decent position before slicing her shot across the face of goal.

I expect this Barcelona team to come out really fast, with really high energy.

But this Barcelona crowd are expectant. And not only are they expectant of a win, they want goals.

Signs of a few nerves from Barcelona early on and Jess Carter's long throw from the right causes a bit of panic.

A sliced clearance but the ball eventually ends up in the arms of Barca keeper Sandra Panos.

This is my first time to this stadium and I think for so many of us it's a stadium you grow up watching on television.

But it's huge. The steep sections around us, the deep red and blue of Barcelona. The flags waving, the fans in here, looking forward to what should be a great game.

It's very early in this match but Chelsea are the team on the front foot. A decent spell of possession ends with a wayward cross from the right drifting out for a goal kick.

Good intent from Emma Hayes' side, though.

A short blast of the referee's and we're underway.

It's Barcelona v Chelsea and there is a place in the Champions League final at stake.

You have to stay in the game and have a really defensive structure on that day.

They're going to have to show that tonight and also be more attacking and cause problems for Paños in goal for Barcelona.

Here come the teams. The home fans are creating a brilliant atmosphere - an atmosphere fit for a Champions League semi-final.

Can Chelsea do the unthinkable, break Barcelona's incredible winning run at home and make it through to the final in Eindhoven?

Nou Camp is steeped in history and you feel it walking around the stadium and speaking to locals.

Emma Hayes and Magdalena Eriksson referenced it several times in the press conference yesterday too.

The city lives and breathes football. There is entertainment everywhere you look outside the ground as Barcelona fans come in numbers hours before kick-off.

Among the names on the back of shirts I spotted are some of legend and some of current superstars - Ronaldo, Messi, Xavi, Alexia, Maria Leon, Lewandowski, Gavi and Bonmati.

There is going to be over 70,000 fans here and the majority will be the football obsessed locals from Barcelona.

It feels like a Champions League semi-final at Nou Camp - and Chelsea will have to cope with that.

It feels like one huge celebration of football. You just have to pinch yourself and give yourself a moment to take it all in. It's just a party atmosphere.

They are expecting over 71,000 fans here for what is one of the biggest nights in the history of Chelsea's women's team. This is a big night for Barcelona, it's a big night for Chelsea.

Not long until kick-off now and the atmosphere is really starting to build.
