It's a simple goal. Marking is terrible - it just takes a glance.
It's a great finish - game on!

A corner is played short, it's whipped in and defender Facundo Roncaglia gets across his man and flicks a header into the far corner.
One more goal for Celta Vigo would put them through...
Facundo Roncaglia
Hello! That changes things!

Let me get this straight Celta have beaten Barca and Madrid this season and it looks like Utd will win both legs.but because they are not playing swashbuckling football everybody gives them stick. Unbelievable.

Another Celta Vigo cross is well defended. As Chris Waddle was saying earlier the Spanish side are lacking the cutting edge they need.

An insight into the meticulous approach to modern-day football was seen in front of the home dug-out just then.
When Michael Carrick was told he was coming on, Jose Mourinho and assistant Rui Faria gathered in a huddle around the veteran midfielder and explained precisely what they wanted him to do with the aid of numerous notes on a laminated sheet.
Even after Mourinho went back to watch the game, Faria carried on for another minute or so before Carrick took off his tracksuit top and made his entrance.

Lyon need one more! In 10 minutes! For extra time...
They have loads of men in the box, a cross is met at the far post and sub Rachid Ghezzal's header goes in off the knee of a defender.
Manchester United 1-0 Celta Vigo (Agg: 2-0)
Marcus Rashford takes a corner, about as well as Harry Kane does, booting it right out the back of the area.

Celta Vigo are a nice football team to watch.
They move the ball well but you can see how teams score against them. They really are lacking in the final third.
Manchester United 1-0 Celta Vigo (Agg: 2-0)
Michael Carrick makes an instant tackle on the edge of the area and is really re-organising everyone around. Paul Pogba is sent out to the left, to stop the dangerous Mallo making so much ground.

Whenever there is an ounce of danger, there are red shirts surrounding the Celta players...
They are doing that really well.
Manchester United 1-0 Celta Vigo (Agg: 2-0)
Michael Carrick is on to see this one over the line. Henrikh Mkhitaryan is the man who comes off.
Manchester United 1-0 Celta Vigo (Agg: 2-0)
A real chance! John Guidetti is free on the penalty spot to meet a cross from Mallo, he just gets his angles and timing all wrong and ends up heading well, well wide.
Got to score those I'm afraid...
Manchester United 1-0 Celta Vigo (Agg: 2-0)
We are entering 'now-or-never- time for Celta I reckon. They need two goals. Daley Blind does his best to help out with a miscued header but it drifts over his own bar.
Manchester United 1-0 Celta Vigo (Agg: 2-0)
A crisp strike from 25 yards from sub Jozabed has Sergio Romero in a spot of bother - but the ball is always swerving away from goal and ends up a few yards wide.

When the Manchester United fans chanted Jose Mourinho's name just then, the Celta Vigo supporters responded with one of their own.
It also started with the words 'Jose Mourinho'. I don't speak Spanish but I don't think the next bit was complimentary.

That is actually a very good save there.
The way Fellaini was running away from the goal there, you didn't think he was going to get there, but he wraps his foot around it and it is going in the bottom corner - a very good save.
Manchester United 1-0 Celta Vigo (Agg: 2-0)
Another decent save from Sergio Alvarez! Marouane Fellaini close to his second of the night as his low shot is sneaking in at the near post but Alvarez claws it out.
Just 20 minutes left now.
Manchester United 1-0 Celta Vigo (Agg: 2-0)
Nemanja Radoja comes off, Theo Bongonda is on for Celta Vigo. Our friend in the comms box is very excited, but that means little I think...

Iago Aspas has had a running battle with referee Ovidiu Hategan all night and it ends with a booking for dissent as he once again complains about not getting a free-kick.
He needs a goal if his side are to have any chance of forcing a comeback. It doesn't look likely at the moment.
