A couple of Roma changes too.

Gianluca Mancini and Mario Hermoso make way for Evan Ndicka and Daniele Ghilardi.

Barcelona are pushing for more goals and Gavi sends a ball into the box but Pau Torres makes an important block.

Some sloppy passes from both sides in this half.

Both losing the ball in the middle of the park.

A double change for Manchester United - Ayden Heaven and Amad make way for Lisandro Martinez and Shea Lacey.

You can not argue that Manchester United have been much better this second half and have played with a lot more desire and urgency.

But if they can not find at least another goal and get a result here their situation remains the same - with Michael Carrick under intense pressure and United bang in trouble.

Now Barcelona makes a triple change as Frenkie de Jong, Gavi and Gabriel Jesus are on for Raphinha, Pedri and Fermin Lopez.

Manchester United have had 16 touches in Roma's box in this second half. Roma haven't had a single one in Manchester United's box.

I think Nicolas Jackson is scared of hurting himself by running into the back post. I think he should be tapping that in.

Aston Villa aren't giving up to their credit and Leon Goretzka sends a header from a corner onto the outside of the post.

The penalty and getting the goal makes a big difference, but since then the energy and desire to get the ball, we are seeing a few more tackles and that lifts the crowd. The crowd are now getting behind the team, and it gives them a bit more belief that they get can something out of the game.

Ayden Heaven goes into the book for going in with studs showing on Matias Soule.

Not a great evening for the 20-year-old.

Zion Suzuki has got to stop this. He has got to learn. He is in one of the biggest environments and you're asking Barcelona forwards to press you.

He makes the save to make up for it but he has to learn.

Harry Maguire is tussling again with Leonardo Balerdi to win the header and he wants a penalty, he thinks he has been dragged down but the Roma man backs off as the ball comes in.

No penalty.

The tide has turned massively here.

Diogo Dalot sees his shot cleared off the line and Roma are massively under the cosh here.

A third corner for United and Bryan Cristante is asking for more from his side.

John McGinn gets beaten too easily by Joao Cancelo but what Cancelo does is brilliant. It's a delightful ball with the inside of his right foot. It's beautifully placed into Raphinha and that should be that.

Devastating and with just so much class. First Cancelo's skill and cross and then Raphinha's sharp finish. That was just too good for Aston Villa.

Delivered to the back stick by Bruno Fernandes and Harry Maguire wins the tussle with Marten de Roon to nod his header wide. It takes a slight deflection and United have another corner.

A nice ball into the box and Bryan Mbeumo is reaching but can't get there and instead it's poked behind for Manchester United's first corner of the match.
