Sisto does the same thing every time he gets the ball - he has got one trick. He is pretty good at it but it is a good save from Romero.

Sergio Romero earns his corn with a superb reaction stop, tumbling back to tip Pione Sisto's shot over the bar after it looped up off Antonio Valencia's leg.

That looked like it was creeping under the bar and in without Romero's intervention.

It's a different pace this half, they have run a little energy out of each other in the first half. Those gaps will probably start to open up. 

Will Jose Mourinho ask one of those star names on the bench to come on and make the difference?

As it is Manchester United are heading back to Old Trafford knowing that they must beat Celta Vigo on the night to go through to the Europa League final and keep that route to next season's Champions League open.

Antonio Valencia wins a corner as he gets down the right and lures in a defender.

Marcus Rashford wastes the set-piece though with a scruffy cross that is hoofed clear by the first defender.

If Manchester United have a weakness at the moment it is in that central defensive area where the Celta players are getting to those headers first. 

Celta Vigo show a glint of danger.

Daniel Wass lofts a neat ball into the United box and Iago Aspas' glancing header, ahead of Eric Bailly, drifts just a yard or two wide.

Paul Pogba with a shot that was neither Arthur or Martha - side-footing high over the top from 25 yards as he got caught between placement and power.

For what is worth, I reckon he is one well-hit long-ranger away from playing with some real swagger.

In the first half, this game was played at a high tempo - these players will be tired - they are not robots. 

If I am Juan Mata, I will make right good use of that. He is a player who can do real damage here.  

United get on the ball at the start of the second half with Jesse Lingard scampering down the left.

He drills a low cross in towards Henrikh Mkhitaryan, but a defender's foot gets to the ball first.

No changes for either side by the way.

We are back under way.

The teams re-emerge onto the pitch to the strains of the A Team.

Time to get us going.

How important is an away goal this evening?

Or could United be relied upon to win on the night at Old Trafford?

Time to call on the likes of Juan Mata, Wayne Rooney and Antony Martial on the bench?

Plenty of questions for Jose Mourinho. And it looks like he wants Rui Faria to do some of his homework.

There have been a fantastic few chances for Manchester United. They are winning on chances at the moment. 

I said Pogba looked up for it in the warm-up and I was right. He looks absolutely fantastic tonight. 

Luke: Man United in desperate need of some attackers and coaches that know how to put a simple chance in the net. It's embarrassing.

Aleks Yakubssohn: Man United seem to be outfighting Celta. seems like the hectic schedule isn't that much of a problem after all.

Richard: Man United should be 2-0 up. Chances wasted. Where have I heard that before? Oh yeah. Every game this season.

I have to say I am loving this game of football. 

It's been played exactly like a cup tie - which I know it is but how many first legs have you seen where it doesn't produce anything. Celta are going for it. and I truly believe Manchester United are going for it too. 

It's one of those games where, in the last 20 minutes, I think the substitutions will play a massive part.

Is this going to be one of those games for United?

There have been plenty of them this season.

A gold-edged plush-paper invitiation to score as Marcus Rashford prods the ball to Jesse Lingard, 10 yards out.

But Lingard's side-foot finish is straight at Sergio Alvarez.

A penny for Jose's thoughts. And Zlatan's.
