The goal has livened this game up a little bit.
It's got City on their toes, even though they're still ahead on aggregate.

The United fans are making all the noise now. Poor old Claudio Bravo has a terrible record of conceding a goal with the first shot he faces, and it continues here - not a lot he could do about that sweet strike though.

That's exactly what United needed to get themselves back in this tie.
They haven't really created any chances, but they've hung in there with five at the back and Matic in front.
And it's Matic who's got the goal. Since he's come back into the side he's been brilliant.
Nemanja Matic
Hello!
First shot of any type for Manchester United = first goal as the free kick is sent towards the near post, Bernardo Silva's clearing header is poor and Nemanja Matic drives a shot through the crowd and into the back of the net.
Game on!

Rodri is late on Jesse Lingard after the Manchester United midfielder had knocked the ball through his legs. The visitors have a free kick on the left side of the City area...

David de Gea is up and OK to continue.
The atmosphere is very flat for a derby at the moment. Still waiting for something to spark it into life.

More than half an hour in, and United still need two goals to level this tie on aggregate.
They were 2-0 up by this stage when they were last at the Etihad in December, but this time they have not managed a single effort at goal - City have had nine.
The United fans are still making plenty of noise, mind, although they have just been drowned out by a rendition of 'Blue Moon'.

So tired of the mob bully mentality. Lingard has been out of form, but look at his record before. People did this pathetic job on people like Smalling, and even on United as a whole. Fake fans. Confusing snide bullying with banter and intelligent comment.

It's a foot-race between Sterling and Maguire - Sterling should have won it.
But just as he's about to pull the trigger, Maguire gets there to poke it away. He had to time that to perfection, and he did.
Man City 0-0 Man Utd (3-1 agg)
What a pass by Kevin de Bruyne! He plays the ball between the Manchester United defence to send Raheem Sterling on his way. The forward charges into the box but Harry Maguire gets across quickly to challenge and knock the ball behind for a corner.
David de Gea then strides confidently off his line to claim the delivery but takes a knock to the ribs by Nicolas Otamendi and is in some discomfort.
Man City 0-0 Man Utd (3-1 agg)
Jesse Lingard, who has been quiet so far, plays a quick ball to Mason Greenwood 35 yards from goal and the striker is fouled by Nicolas Otamendi. Fred lifts the ball into the area, trying to find Nemanja Matic, who goes down under pressure from City defenders as he tries to meet the delivery.

City have been very dominant so far.
Man City 0-0 Man Utd (3-1 agg)
Wonderfully timed run by Riyad Mahrez to get in behind the Manchester United defence and bring long ball forward by Kyle Walker under control.
Mahrez holds the ball up to wait for Sergio Aguero to get into the box but his cross is behind Aguero and the striker cannot direct a header on target.
Man City 0-0 Man Utd (3-1 agg)
Bernardo Silva leads a Manchester City attack. He has four team-mates in support, passes to Sergio Aguero who in turn finds Kevin de Bruyne but the midfielder drives an effort from the edge of the box over.

United have improved in the last few minutes. They've started to bite a bit, they're at least trying to make it a little more difficult for City.
Man City 0-0 Man Utd (3-1 agg)
Manchester City players seem a little uncertain where their team-mates are when attacking as Sergio Aguero plays a quick ball towards the centre of the box but there is no-one there.
