Arsenal need a goal back now to really threaten a tense finish and they have a free kick in a good position on the left side of the box but the delivery is put too close to Almuth Schult.

Lena Oberdorf is urged to shoot from outside the box by the home fans and she hits a dipping effort at the Arsenal goal but Manuela Zinsberger has it covered.

Wolfsburg also make a change with Sveindis Jane Jonsdottir replaced by Ewa Pajor.

Arsenal make a fourth change as Laura Wienroither comes on for Noelle Maritz with just over 10 minutes left.

Arsenal look to capitalise on this good spell with some fresh legs as on come Jordan Nobbs and Nikita Parris for Frida Maanum and Katie McCabe.

Arsenal have another corner soon after but this one is well claimed by Almuth Schult.

Still, this is the visitors' best spell of the game.

Stina Blackstenius is almost onto the end of a cross from the left but Dominique Janssen is able to get a foot to it first and put behind for a corner.

From the delivery Lotte Wubben-Moy also gets her head to the ball from close range.

Arsenal are upping the pressure a bit now.

Steph Catley makes a crucial tackle to prevent Svenja Huth from getting away down the flank.

One hour in and it has been better from Arsenal in this second half.

If the 90 minutes ends all square there will be extra time and then possibly penalties.

Almuth Schult spills a ball into the box and Vivianne Miedema is onto the loose ball but can't turn into the back of the net.

Better from Arsenal, though.

Leah Williamson puts too much on a free kick into the box and although Caitlin Foord chases after it, she can't keep it in play.

Noelle Maritz then looks to get away down the right but is pulled up for a push on Felicitas Rauch.

Vivianne Miedema tries to force her way through the middle but there's too many Wolfsburg players there.

Wolfsburg threaten from the restart as the ball comes in from the right but Jill Roord can't quite get the connection she'd like and Manuela Zinsberger gathers.

Arsenal get the second half under way as they look to find a way back into this.

Arsenal do make a change for the second half as Caitlin Foord is on for Tobin Heath.

They've had another go at clearing off the confetti at half time and they've done a pretty good job. Not much left out on the pitch now.

There's another quarter-final second leg to come tonight with Lyon hosting Juventus. The Italians lead 2-1 from the first leg.
