Ludmila again the danger. Tonni Duggan clips a ball over the top and the Brazilian is on to it in a flash down the right side of the area, but she can't pick out ra red and white shirt and Maren Mjelde gets it away.

Worth noting that despite this being at the neutral venue of Monza, it's the away leg for Chelsea and the away goals rule is still in force.

That means if Chelsea score once, Atletico would need to score four times, as a 3-3 draw would put the Blues through on away goals.

Chelsea have a toe in the quarters, just 45 minutes to see through.

Two other games are on right now.

Brondby are level 1-1 with perennial Champions League winners Lyon - as a standalone result that would be worth the raise of an eyebrow, but Lyon hold a 3-1 aggregate lead.

And it's goalless between LSK and Wolfsburg, with the German side 2-0 up on aggregate.

No goals in that half but you can watch back Chelsea's two they scored in their weekend win over West Ham, along with some top-noch analysis.

Atletico have created very little in that first half, with Toni Duggan's dipping volley from the edge of the box the closest they have come.

But Ludmila has looked a real threat, stretching the Blues and looking lively when she wanders out wide. Chelsea will need to be wary of her pace.

Just had a gander at Chelsea's Twitters and they're saying Beth England went off with a knock to the head - must have been that clash with Merel van Dongen.

As you were then as we end the first half.

Chelsea will be pretty pleased, you'd think - the quarters beckon.

Great chance. Chelsea sould do better here.

Fran Kirby breaks away from a defensive corner and messes up the pass to set the rampaging Maren Melde free. Laia Aleixandri gifts the ball straight back to Melde though and it needs a last-ditch tackle from her centre-half partner Mergel van Dongen to stop the shot coming in.

Interesting. Beth England is coming off. It doesn't look like anything obvious is amiss but maybe it's a precaution for a minor knock - she heads straight to a seat on the Celsea bench.

Guro Reiten comes on.

Lightning Ludmila! Atletico's Brazil forward makes Niamh Charles look like she's running through treacle as she whizzes past her and wins a corner.

Chelsea get it half-clear and Toni Duggan displays all the technique in the world to catch a sweet volley on the ede of the area, which Ann-Katrin Berger does well to hold as it just pops up off the turf in front of her.

A quiet day so far for Chelsea's Ji So-Yun, with most of the Blues' success coming down the left side rather than through the middle.

A decent bit of link-up from the Korean does get Chelsea going down the left but it comes to nothing.

Leicy Santos pulling out the tricks for Atletico, cutting in from the left with the help of a Maradona turn. It gives her space to let fly from 20 yards but it's down the throat of Ann-Katrin Berger.

Atletico Madrid 0-0 Chelsea (agg 0-2)

Two ouches in a couple of minutes!

Niamh Charles has a problem with her eye and we get a seriously close close-up of some drops being squirted on to her eye ball. Not for the squeamish that one.

Millie Bright and Maren Mjelde get in a right pickle, bouncing off each other as they both go up to head away a long ball.

It gives Deyna Castellanos the chance to have a pop from 20 yards and it dips just over the Chelsea bar.

The corner drops to Millie Bright on the edge of the area and she lashes a half-volley that looks like it will fly in - if weren't charged down.

Chelsea growing into this now and Sam Kerr in particular is finding pockets of space on the left.

The Aussie drives in a cross that Beth England tries to get her head on, but only makes contact with the cranium of Merel van Dongen.

They win a corner though.

Big chance for Chelsea to put this out of sight,

Sam Kerr's low cross is almost diverted in by Grace Kazadi. Hedvig Lindahl saves but it falls to Fran Kirby on the corner of the area and she clips an effort over the bar.

Gotta hit the target there.

Another Atleti corner and no messing from Santos this time, whipped in but two firm fists from Ann-Karin Berger get it clear.

Atletico recycle and Ludmila tries her luck from distance but it flies wide.

Chelsea not seeing muh of the ball but they won't be too bothered, with Atletico struggling to force anyting of note. Here's a chance to get into the box from a corner for the Spanish side, but they opt fpr a short one and Leicy Santos gets in a muddle - chance gone.
