Ellie Carpenter has fired 10 crosses into the Hacken box in the opening 40 minutes, but Chelsea haven't been able to make any of them count so far.

But she's not had to do anything magical yet.

Lucy Bronze fires in a cross and it takes a big deflection off Emma Ostlund, bouncing up and off the crossbar.

Hacken's Aivi Luik, at the age of 41, is the oldest player to feature in the Women's Champions League.

The Australia defender has her work cut out tonight to try and keep Chelsea out.

What a watch from Falk. It had some venom on it from Carpenter.

It was the right option [to shoot], the cut-back would've been to a congested area.

Ellie Carpenter had options in the middle of Hacken's box but she tries her luck and her strike is saved by Jennifer Falk.

It was a dangerous ball into the Hacken penalty area from Ellie Carpenter but it filters all the way through without finding one of her team-mates.

Most of Chelsea's attacking play is coming down that right-hand side.

Another Chelsea goal ruled out.

Wieke Kaptein takes the ball on the half-turn on the halfway line before launching the ball up the pitch for Melvine Malard.

The French striker had gone a tad too early and the offside flag goes up straight after she slots past Jennifer Falk.

Sjoeke Nusken is played through by Keira Walsh, but the German midfielder's attempt at a cross - or was it a shot? - sails straight into the gloves of ex-Liverpool keeper Jennifer Falk.

Every time Chelsea go on the attack there's a wall of Hacken defenders in the way. Melvine Malard has a strike blocked and Alyssa Thompson can't find a way through either.

Such a let off for Chelsea.

It was brilliant defending by Lucy Bronze to stall progress and force an error by Olvestad.

Chelsea get caught off guard and it's suddenly three against two, but Tilde Karlsson goes alone and can only find the side-netting.

I don't think her team-mates were too impressed that she didn't cut the ball back for one of them to run onto.

A poor touch from Lucy Bronze almost allows Hacken through on goal, but the England defender recovers, blocks Tilde Karlsson's effort and then drives up the pitch.

Chelsea really caught Hacken on the back foot. It was lovely build up play.

But could Ellie Carpenter have pulled the trigger first time?

Taking that touch gave the defenders a chance to close down, the angle gets tighter. Chance gone.

Ellie Carpenter is at the centre of every single Chelsea attack at the moment. Perhaps she should have shot a second earlier there, but she takes an extra touch, tightening the angle before she rifles into the side netting.

A sublime delivery from Ellie Carpenter almost curls in at the backpost, but Thelma Palmadottir retreats and puts her head on it.

I think Tilde Karlsson surprised everyone there by going for a cheeky chipped shot rather than crossing it for one of her team-mates.

Luckily for Chelsea, Livia Peng was alert and she tips it over the bar.

Wieke Kaptein is off on a celebratory run after flicking the ball into the far corner of the net, but the whistle blows and the flag is up.

It looked like Lexi Potter was in an offside position as she stood her ground in front of the goalkeeper.
