That is all for this particular blog, thanks for following along. Post-match reaction to come from Mourinho overnight.
We will also be back tomorrow evening to bring you live coverage from The Hawthorns, where Chelsea will seal their fifth top-flight title if they manage to overcome West Brom. Everton also host Watford at Goodison Park.
Goodbye for now.
That was certainly an explosive finish to an otherwise relatively comfortable evening for United. Guidetti will be thinking about that last-gasp miss for some time to come, I'm sure.
The influential Bailly will be a big loss for the Red Devils' first Europa League final, which takes place on Wednesday 24 May at Friends Arena in Stockholm.
Manchester United reach the Europa League final for the first time
Manchester United 1-1 Celta Vigo (Manchester United win 2-1 on aggregate)
Incredible late drama.
A last-ditch ball forward is flicked on by Hernandez and Cabral feeds it to Beauvue. The Guadeloupe international tees up Guidetti, who cannot turn the ball home from close range.
What a miss right at the death. United are through.
Ajax have survived a hairy evening in Lyon to reach a first European final since 1996. Will United join them?
Herrera thrashes the ball home but the whistle had already gone for a foul by Pogba on Mallo.
It won't count.
Lyon 3-1 Ajax (Ajax win 5-4 on aggregate)
It's all going off at Old Trafford. An almighty scuffle breaks out and both Bailly and Celta goalscorer Roncaglia receive their marching orders.
They are still at it as they head towards the tunnel. Mourinho reacts by withdrawing Rashford in favour of Smalling.
The fourth official signals SIX minutes of added time. Can United hold on?
Red card: Facundo Roncaglia (Celta Vigo)
Red card: Eric Bailly (Manchester United)
Poor old Viergever. His own goal is followed by a second yellow card.
Roncaglia heads home for Celta after a whipped cross from Bongonda. One more and they are through!
Red card: Nick Viergever (Ajax)
Goal: Manchester United 1-1 Celta Vigo (Facundo Roncaglia)
Lingard squares up to Gustavo Cabral before seeing a shot cannon back off the defender.
At the other end, Bailly produces a superb block. Celta's half-hearted appeals for handball are waved away.
A nail-biting final few minutes ahead in France. Rachid Ghezzal's header from a Maciej Rybus cross deflects in off Viergever.
Ajax now lead 5-4 on aggregate...
Goal: Lyon 3-1 Ajax (Nick Viergever OG)
Herrera can have no complaints as he is cautioned for a foul on Beauvue. Bailly rises to head away the free-kick before the ball runs behind for a goal kick, despite an attempted clearance from Valencia.
Celta have been in the ascendancy for much of this second half. Jozabed and Bongonda have both added fresh impetus off the bench, but the goal-shy Galicians just do not look like scoring.
With his final roll of the dice, Berizzo sends on Claudio Beauvue in place of Sisto.
Mkhitaryan, who has taken a couple of knocks in this second half, is the man to make way for Carrick.
Given too much space to operate by Mkhitaryan, Mallo swings in another decent cross from the right flank.
An unmarked Guidetti positions himself nicely between Blind and Bailly, but gets his close-range header all wrong and the ball sails wide.
Romero concedes a cheap corner and Rashford is unable to get much purchase on his clearing header at the front post. The ball bobbles off Bongonda before Guidetti is whistled for pulling back Darmian.
Michael Carrick is preparing to enter the fray.
Jozabed collects possession from Aspas in plenty of space and unleashes a muscular right-footed shot that whizzes past the post. A diving Romero seemed to have it covered.
