Unfortunately, that's all we've got time for tonight. I've been Oliver Emmerson, taking you through Villarreal 1-0 Liverpool. Until next time, goodnight.
Nightmare for Liverpool, who were set to take a good result back to Anfield, but now face the prospect of chasing a defecit having not scored an away goal. They must score two at Anfield next week to go through, or win 1-0 and progress on penalties. Deserved for Villarreal? Perhaps, they were probably the better team. Liverpool will rue Allen's missed chance in the first half, and Lallana being flagged offside in the second half.
Full-time: Villarreal 1-0 Liverpool (Adrian)
90+2: Cruel for Liverpool, but an excellent counter-attack from the home side. The Reds tried to press them in midfield but had it passed around them, Suarez getting in-behind Toure before playing the ball across to Adrian for a tap in.
GOAL! Villarreal have stolen it, Adrian!
90: Three minutes of added time.
89: Jurgen Klopp making just his second substitution of the game, Benteke on for Firmino for the closing minutes.
88: Crikey, Liverpool break from the corner as Moreno pinches the ball from Suarez, but he can only blaze a shot over after using his pace to get clear.
87: What a save! Bakambu's had a quiet night, but he finally gets in-behind Liverpool's defence there. One-on-one with Mignolet, the striker should score, but the Belgian produces a stunning save to keep the ball out.
86: Ibe charges down the left and beats his man, standing up a cross to the back post which is nodded wide by Clyne.
84: Kevin Gameiro has equalised from the penalty spot in the other semi final. Shakhtar Donetsk 2-2 Sevilla.
80: Poor delivery from Denis Suarez, Mignolet catches comfortably.
79: Chance for the home side from a free-kick as Allen fouls Bakambu in a dangerous area. One goal for either team would change the dynamic of the tie hugely.
76: Villarreal forced into their last change as Bailly limps off with a hamstring problem. Musacchio, their first choice centre-back, comes on, but he's not totally fit. Daniel Sturridge time for Liverpool perhaps?
75: Fantastic pass from Allen over the top of the defence to Lallana, who was in on goal. The flag went up for offside, replays showing that it was the wrong decision...
74: And here's another change for the hosts. Soldado off for Adrian.
72: Change for Villarreal. Dos Santos off, Castillejo on.
65: Off the post! Liverpool now hit the woodwork, just under 20 minutes after Villarreal did. Milner fed Firmino, who span well just inside the area, hitting an early shot onto the right hand post.
60: Jaume Costa picks up a yellow card for a cynical foul on Clyne as the full-back looked to hurdle down the right flank.
55: Hearts in mouths for a moment as there's a goalmouth scramble in the Liverpool area, Mario eventually shooting over.
52: Coutinho update, he's feeling unwell. That's why the Brazilian was brought off at half-time, giving Jordon Ibe a huge opportunity to shine. The youngster has been on the periphery in recent weeks, struggling for gametime and form. Can he change things tonight?
51: Better going forward from the Reds, Ibe and Milner playing a one-two before the latter has a shot deflected out for a corner. Villarreal though, clear easily.
46: Off the post! Poor defending from Liverpool at a corner, Bakambu getting a free header at the near post, but it's the woodwork that he hits.
45: Underway in the second half.
Interesting change for Liverpool, Coutinho off for Ibe during the interval. An injury perhaps? We shall see.
In the other semi final, after going behind early on, Shakhtar have made a comeback and are now 2-1 ahead against Sevilla.
Not a great half for the neutral, but an interesting one all the same. Joe Allen will be regretting not putting away Liverpool's chance of the night so far, but you'd say that the hosts have had the better of things.
Half-time: Villarreal 0-0 Liverpool
45+1: Into one minute of added time. Liverpool corner, headed to safety.
42: Half the ground thought it was in! Bruno, composed on the ball, sets up Soldado to shoot - the Spaniard striking just wide.
40: Clyne's shot is deflected to Lallana, who tees up Coutinho. The Brazilian decides to shoot on his weaker foot from an unlikely angle, and it shows, the ball travelling way over.
36: Great defending from Toure as Mario slides a ball across, only for it to be intercepted. The ball breaks to the full-back again, who goes to shoot, Moreno doing well to block.
31: He's been off for a few minutes and had some treatment, but the winger is back on. Elsewhere in Europe, it's 1-1 between Shakhtar and Sevilla.
27: Problem for the hosts, Dos Santos down on the ground clutching his leg after a coming together with Alberto Moreno.
21: Doggid defending by Liverpool, Lucas throwing himself in front of Pina's shot, just after the same player had a curling effort saved by Mignolet. The ball had broke kindly for Dos Santos to shoot in the area, but he chose to roll the ball back, giving Liverpool's 'keeper some more time to set himself.
18: Liverpool enjoying some possession in the opposition half after a difficult few minutes. Nathaniel Clyne is certainly enjoying some time and space down the right hand side, but is yet to make much use of it.
15: Lucas Leiva, who hasn't scored in about 703 years, shoots wide after Firmino's cross from a short corner is headed away.
11: Just wide! Bruno dinks a free-kick into Soldado's path, the forward firing just wide of Simon Mignolet's far post. Very, very close.
5: Ooooh, Allen! Lallana's cross is deflected to the Welshman just inside the penalty area, Liverpool fans frustrated as he shoots straight at Asjeno.
3: First chance for Villarreal to counter attack as Coutinho loses the ball in midfield, but an excellent challenge from Moreno on Dos Santos pushed the ball to Mignolet.
0: Kick-off!
Almost kick-off time, the two teams emerge onto the pitch to the Europa League anthem. Handshakes and team photos to commence.
The big team news for Liverpool is that Daniel Sturridge isn't started by Klopp, who's preferred to go with Roberto Firmino in the main striker's role, as he's done away from home in some big games this season. Lucas Leiva and Joe Allen are the midfield pairing in the absence of Jordan Henderson and Emre Can, whilst Toure replaces Sakho at the heart of defence.
Villarreal will be delighted that Jaume Costa is fit to start at left-back, as he was a doubt. Sergio Asjeno has been given the nod in goal, picked ahead of PSG loanee Areola.
Liverpool substitutes: Ward, Skrtel, Smith, Chirivella, Ibe, Sturridge, Benteke.
Liverpool XI: Mignolet, Clyne, Toure, Lovren, Moreno, Lucas, Allen, Milner, Lallana, Coutinho, Firmino.
Villarreal substitutes: Areola, Adrian, Musacchio, Rukavina, Samuel, Castillejo, Trigueros.
Villarreal XI: Asjeno, Costa, Ruiz, Bailly, Mario, Bruno, Pina, Suarez, dos Santos, Soldado, Bakambu.
We've got the team news in! Let's take a look...
Neither team managed a win at the weekend, both resting certain key players and taking a point from their league games. Goals from Daniel Sturridge and Adam Lallana saw Liverpool race into a 2-0 lead at home to Newcastle United, only for the Reds to let it slip and draw. Villarreal were as usual good defensively, but couldn't score as they were held to a 0-0 stalemate by Real Sociedad at home.
Key man (Liverpool): Philippe Coutinho is the obvious dangerman for the Reds, a player admired all across Europe. He's come on leaps and bounds since moving from Inter Milan just over three years ago, and has added goals to his naturally creative play this season. The attacking midfielder has 12 in his 37 appearances in all competitions, including a remarkable solo goal away to Manchester United in the last 16.
Key man (Villarreal): Cedric Bakambu has been excellent for Villarreal since joining from Turkish side Bursaspor last summer, and boasts an impressive total of nine goals in 11 Europa League appearances this season. He'll be looking to improve that record against Liverpool tonight.
Liverpool are unbeaten in their 12 games so far this campaign, something which no side has ever done before during one season of the competition. They topped Group B with two wins and four draws, before beating Augsburg 1-0 on aggregate in the last 32. Things really got interesting after that, as they met Manchester United for the first time in European competition. The Reds rose to the challenge, winning 3-1 on aggregate, setting up a quarter final with Borussia Dortmund. After a 1-1 draw in Germany, BVB went 3-1 up in the return leg at Anfield, leaving Liverpool with the unlikely task of scoring three goals in the last half an hour to progress. They managed it though, Dejan Lovren heading in infront of the Kop in stoppage time to win it.
How has each side got here? Let's take a look. Villarreal came second in their group, winning four matches consecutively in-between losing the first and drawing the last. They defeated heavy favourites Napoli in the last 32, winning a tie which nobody expected them to progress from 2-1 on aggregate. Bayer Leverkusen were next up, with the Yellow Submarine not conceding over two legs as a 2-0 win at home set them up with a quarter final tie against Sparta Praha. Dominant again, the Spaniard's won 2-1 at home and 4-2 away, 6-3 on aggregate.
Each Europa League semi-final first leg is being played tonight, with Shakhtar Donetsk - Sevilla the other fixture, in Ukraine. That pair, along with the two teams were covering here, are battling for a place in the final, set to be contested on May 18 in Basel.
Good evening and welcome to VAVEL UK's live minute-by-minute commentary of tonight's Europa League semi-final first leg between Villarreal and Liverpool. Kick-off at the El Madrigal is set for 20:05 BST, but stick with us before then as we build up to the game and get the confirmed starting XI's.
