Chance for Austria Vienna, from a well-worked short corner. A cross comes in, unconvincing goalkeeping from Livia Peng, who fumbles the ball and it drops to Virginia Kirchberger.

She is falling backwards and has a near open goal to aim at, but can only shoot over the top. A warning to Chelsea that more work is needed.

Am expecting many more puns to be on the bill.

Melvine Malard is eyeing up a goal on her first Chelsea start. Her France team-mate Sandy Baltimore sets up Malard, who opts to curl it at the far post, but she doesn't get enough whip on the ball and wide it goes.

Alyssa Thompson is quick, we know that but those spaces down the channels are wide open. That's exactly where she will be dangerous. She had every right to go for the shot there.

Almost brilliant from Alyssa Thompson. She gets past Tatjana Weiss with ease down the right flank, getting into the penalty area. She shoots for the far post, but fires just wide.

Soon after, Melvine Malard heads just off target.

There are many more goals for the taking here for Chelsea.

That will be a concern for Chelsea as star midfielder Keira Walsh heads straight down the tunnel after signalling that she wanted to come off.

It is not yet clear how serious the issue is, but Chelsea face Arsenal in the Women's Super League on Sunday.

It could have been two.

Austria Vienna just can't cope with the pace and trickery of Alyssa Thompson and she runs at the away defence, before setting up Sjoeke Nusken.

The Germany international could have gone for goal herself, but instead tries to find team-mate Sandy Baltimore, but the final ball is not great and Austria Vienna are able to clear.

Austria Vienna's Modesta Uka thinks she is through on goal, but she had clipped the heels of Kadeisha Buchanan and is called for a foul before she can get a shot away.

You don't see this celebration too often.

Don't try this at home.

Chelsea are going to be forced into an early change as Keira Walsh is going to have to come off for Lexi Potter.

Wieke Kaptein hit a warning shot earlier on in what has been a competitive match.

It was expected to be a walkover for Chelsea but the Dutch attacker scored a thunderbolt strike with her second effort and you now wonder if this will remain close.

Austria Vienna came into the match as heavy outsiders and one local outlet pointed out that Chelsea Women's squad is worth more than Austria Vienna's men's and women's teams combined.

Also, Chelsea are clearly playing with a back four, despite the Uefa teamsheet listing them in a 3-5-2 formation.

A chance for Vienna to draw level as a corner from the right drops to Katharina Schlechtl and she is unmarked and able to produce a looping header from the back of the box.

Luckily for the Blues, the ball drifts just wide.

Look at that space she has! It's an absolutely brilliant strike and that is definitely one we're going to be talking about for a while and one she deserves.

What a player she is and what a strike.

Austria Vienna are looking sharp. They've started fast and furious. They're good at carrying the ball - certainly matching Chelsea. Definitely a team not to be complacent about.

Chelsea’s only previous meeting with an Austrian side in the Women’s Champions League ended in a 6-0 win over St. Polten in the league phase last season.

A first chance for Chelsea as Alyssa Thompson is far too quick for the Vienna defence down the right flank and she pulls the ball back and Wieke Kaptein's side-footed effort is saved just in front of the post by Jasmin Pal.

Patricia Pfanner of Austria Vienna has the first shot on the game, but it is straight at Livia Peng in the Chelsea goal and he comfortably catches the ball.

Austria Vienna captain Carina Wenninger, moving forwards from a centre-half position, wins a corner off Keira Walsh, but Chelsea clear their lines, thanks to a strong header from Kadeisha Buchanan.
