Celta Vigo v Manchester United - As it happened
The end
What a win for United. Solid performance from Mourinho's men and they come away with a great result for the second leg. It was a tight fixture throughout, and Rashford scored the only goal from a great free-kick.
Hugo Mallo is replaced by Beauvue
5 added minutes
Smalling on for Young
Young is down
Another injury blow for Mourinho? The winger is holding his hamstring. A substitution lining up...
Pogba close!
Pogba took the free kick having seen Alvarez off his line and it is only just wide.
Yellow card Pogba
For time wasting in a free kick.
Martial replaces Rashford
A bit of a scuffle as Celta players have a go at the striker for walking off.
Young on for Mkhitaryan
So close United!
Lingard smashed at goal from 12 yards and it is inches wide with Alvarez beaten.
Wass is replaced by Jozabed
Iago Aspas wide!
Celta look for an equaliser, and Aspas volleys towards goal but it is off target.
United take the lead!
What a goal from Rashford. Blind stepped over the free kick and Rashford curled the ball into the top far corner. The strike completely wrong-foots Alvarez who cannot reach the ball.
GOAL!
Yellow card Mallo
The defender had to stop Rashford who was bursting into the box.
What a chance Celta!
Sisto's shot takes a deflection and it is dipping below the bar, but Romero does well to tip the ball behind.
Even start to the second half
Celta comfortable on the ball now. Still very tight defensively.
Chance Celta!
Wass crossed into the area and the ball off of Aspas' shoulder is very close to the left upright.
Pogba shoots over the bar
The midfielder went for a strike from 25 yards but it flies well over.
Celta get the second half underway!
No changes at the break.
We're back!
The players are out for the second forty-five minutes.
Half time
No stoppage time added. Still nothing between the two sides as they head to the dressing rooms. United have had at least three clear chances but Alvarez has done well. They might come to regret the missed opportunities...
Sergio Alvarez again!
It is not clearly dominant from the visitors, but they are enjoying the clearest chances. The keeper does a fantastic job to deny Lingard this time. The midfielder only had the keeper to beat and should have done better.
Chance United!
Once again Sergio saves. Mkhitaryan is through on goal and the keeper does very well to deny his left-footed shot.
Yellow card Fellaini
The Belgian with a strong and unnecessary challenge on Hernandez.
Sisto shoots!
Sisto again from the left, and his curling shot is saved by Romero.
Sisto shoots wide!
The winger went for the long shot, but it did not trouble Romero as it bounced off target.
What a save Sergio Alvarez!
Rashford did brilliantly to cut inside from the left. His strong shot was going into the top far corner and the keeper put out a strong hand to send for a corner.
Wass shoots!
The Danish midfielder let fly and his effort is wide of the left post.
Celta take a step forward
Great spell of possession from the hosts, setting United on the back foot. Aspas and Wass with chances to shoot but the defence closes down.
Chance Celta!
The clearest chance yet as Wass heads from the back post towards goal and the ball falls well wide.
The battle for possession continues
The midfield area very congested.
Rashford looking dangerous down the left
The youngster has had a couple of balls fed into his path down the left channel. He will be a threat this evening if he is given space.
Mkhitaryan first shot blocked
Slow start to the game as Celta defend patiently. Pogba sitting quite deep, almost between the centre-backs.
United on the front foot
First touches from Rashford and Pogba. United look to be out to attack...
Manchester United kick off!
The semi-final is underway at Balaidos!
Kick off moments away
Captains Hugo Mallo and Antonio Valencia shake hands with the officials.

Celta already making history
The Spanish club have never come this far, and coach Berizzo wants to go further.
Man United could make history in Europe
The Red Devils look for a place in the final, and if they go on to win the competition they would join an elite group with four other legendary clubs.
Danger up front from Celta
Iago Aspas is looking for his 25th goal of the season. Only Messi, Suarez and Ronaldo have scored more La Liga goals in the current campaign.
Four men back for United
No sign of Jones, while Mata and Smalling are on the bench. As mentioned Pogba starts, alongside Bailly.

Lineups are in!
Celta Vigo: Sergio; Hugo Mallo, Cabral, Roncaglia, Jonny; Wass, Radoja, Pablo Hernández; Aspas, Guidetti, Sisto
Manchester United: Romero, Valencia, Bailly, Blind, Darmian, Herrera, Fellaini, Lingard, Pogba, Mkhitaryan, Rashford
Manchester United travel to Celta Vigo hoping to get bring back a good result for the second leg at Old Trafford. Celta have lost their last three La Liga clashes but should not be underestimated by Mourinho's men, as they have done great to reach their first Europa League semi-final. No notable absences for the home team, aside from former Manchester United striker Giuseppe Rossi. The Red Devils could receive the boost from up to five returning players: Bailly, Pogba, Mata, Jones and Smalling. Rojo and Ibrahimovic are still out for the season.
