Barcelona are beating Leuven 1-0 at the break in their game, thanks to Alexia Putellas scoring from the penalty spot in first-half stoppage time.

Three more games take place at 20:00 BST:

• Atletico Madrid v Juventus
• Manchester United v Paris St-Germain
• Benfica v Twente

Bayern had more possession - 57.1% vs 42.9%, but that's not what matters.

Two shots to Arsenal's nine, one on target to the Gunners' four.

Oh, and no goals to Arsenal's two.

The hosts haven't found their groove.

Excellent performance from Renee Slegers' side. I think it's been brilliant from Arsenal, but for Bayern Munich, they need to make some tactical changes.

Overall, Arsenal have been excellent in defence and in attack.

No added time whatsoever. Arsenal lead 2-0 at the break.

The visitors have been excellent, with their high press causing all sorts of problems in the final third.

The ball is chipped over to Momoko Tanikawa behind the Arsenal back line but she's a long way behind and the flag is up.

That's the closest Bayern have come to threatening for a while.

Caitlin Foord drills a low effort towards the near post from the edge of the area, but it goes wide.

Should she have slotted it across to a teammate instead? Maria Grohs seemed ot have it covered.

Bayern manage to build up a period of sustained possession, but they can't get the ball out of their own half.

This has been an excellent display from Renee Slegers' side.

It has been a really complete performance from Arsenal and it has been difficult for Bayern.

They need someone who can put their foot on the ball in the midfield area.

Beth Mead and Katie McCabe knock the ball between themselves as they play a short corner.

Mead drills an expert delivery towards the back post but it's headed behind by Lea Schuller for another corner.

Nothing comes from that one.

Bayern have had the majority of the possession, but they can't get out of their own half.

Arsenal's high press isn't showing any signs of slowing down. They keep looking to win the ball in the final third.

Stina Blackstenius is in the mood for a goal. She sends another effort towards the target but it goes wide of the far post.

That was a great ball. Love this from Katie McCabe.

A player of Stina Blackstenius' quality will expect to do better.

Arsenal are relentless in their pressure and Bayern can't get out.

Nearly a third....

A whipped delivery from Katie McCabe finds Stina Blackstenius in the box, but her first-time effort goes just wide.

Bayern Munich are struggling.

One of the best players in the world, Mariona Caldentey.

Arsenal have been absolutely ruthless. Caldentey takes a touch, no backlift. Fantastic strike.

An excellent move from Arsenal!

Beth Mead slips the ball to Alessia Russo, she cuts it back to Stina Blackstenius, but her effort ratchets off the crossbar.

Nearly...

Emily Fox bursts down the right-hand side and knocks the ball towards Caitlin Foord in the box, but it has just too much power on it and is out of reach of her teammate.

Better from Bayern.

Klara Buhl runs down the left, catches her marker off guard and feeds Lea Schuller on the edge of the box.

She gets an effort away but it doesn't trouble Daphne van Domselaar.

Arsenal are in control here and they haven't been perfect, giving the ball away a couple of times when they go forward.

Beth Mead tries to send a drilled delivery towards the penalty area but it's intercepted.

A lovely backheel from Beth Mead finds Alessia Russo as Arsenal build through the lines.

Russo plays it to Mariona Caldentey, but her effort from distance is a comfortable save for Maria Grohs.
