Manuela Zinsberger does well to punch a fierce strike from distance by Lynn Wilms away!

Wolfsburg needed to remind Arsenal they're here after absorbing plenty of pressure from their hosts since the opener. The Gunners goalkeeper took no chances with that one.

It's brilliant from Blackstenius, she stays putting the pressure on the defence [when the ball comes forward]. It's one of those awkward ones where as a defender you don't know if your keeper is coming to get it or if you should deal with it.

Blackstenius takes it around the keeper and manages to put in a fantastic finish.

That is a huge goal. The whole stadium were on their feet celebrating because it had been a very slow start from Arsenal.

They probably won't dominate possession but that's where they can get at Wolfsburg, with direct balls in behind when the space opens up.

Stina Blackstenius didn't give it up and got her reward.

Wolfsburg are wobbling but that was astute recovery defending from Wilms.

Arsenal 1-0 Wolfsburg (agg 3-2)

You may not be surprised to learn that a VAR check is being carried out over a possible foul by Blackstenius...

The goal is given! For the first time ever in a game against Wolfsburg, Arsenal are ahead!

You don't neccesarily get used to it, being without the likes of Beth Mead and Vivianne Miedema. But when you then add Leah Williamson, Kim Little, Caitlin Foord to that list, it does get harder to manage.

But what you will see today is that they have found a way to get their best possible line-up on the pitch, albeit with a slightly adjusted style, like we saw in the first leg.

I think it is important that they just stay in the game as long as they can, as this Wolfsburg side have an incredible threat in the final third and you won't want to give them too many chances.

Sveindis Jane Jonsdottir has pace to burn - she's recorded the highest speed of any Wolfsburg player in this season's competition so far - and is looking sharp here.

Arsenal try to send Stina Blackstenius clear with a ball through the middle, but it bounces through to Merle Frohms.

Well, that VAR check very quickly quietened the Arsenal fans down! It took almost two minutes to come to the conclusion it wasn't a penalty.

A nervous wait and manager Jonas Eidevall was watching the referee by the pitchside monitor the entire time.

A huge cheer went up in front of me in the stands when the decision was made.

Rachel Corsie
Scotland and Aston Villa defender on BBC Radio 5 Live

For me, that isn't a penalty.

That is one of those examples where VAR has become a bit pedantic about the letter of the law and what the rules actually saw.

These happen in games and it's a case where we really should just play on.

This has been a useful start from Wolfsburg. Alex Popp and Jill Roord are chasing Arsenal down with energy and intent.

Huge relief for Arsenal. That would have been hugely unlucky for Lotte Wubben-Moy after the ball dropped between the defender and Sveindis Jane Jonsdottir.

Alexandra Popp has seen a little early action, attempting to create danger with typical directness and energy.

How telling will the captain's involvement prove tonight?

There's a huge roar as Wolfsburg kick us off.

Arsenal apply early pressure. A good start could be so important for these sides.

Wolfsburg have had a huddle. Arsenal have exchanged high-fives.

Vivianne Miedema is among Arsenal's absentees who are here.

The forward has just watched the teams emerge and hear the Champions League anthem on the pitch. We're almost ready to go!

Arsenal forward Beth Mead speaking on Dazn: "It's not a situation you want to be in [to be injured] - same with the other injured girls. Days like today - a historic occasion, sell out at the Emirates - you want to be playing in these games.

"Our roles have changed a bit, but in the changing room, Me, Leah Williamson, Vivianne Miedema, Caitlin Foord, Kim Little, we'll all get around the girls and try to help them the best we can.

"The manager has told the girls to enjoy the occasion. You put yourself under so much pressure but you're playing at the home of Arsenal, in front of so many fans. Go and enjoy it!"
