Key events
GOAL! Bayer Leverkusen 1-0 West Ham (Hofman 83)
The substitute strikes!
82 mins: Wirtz cuts in from the left but his shot from 20 yards is straight at Fabianski.
Aguerd is receiving instructions on the touchline.
80 mins: West Ham are up to a whopping 28% possession.
79 mins: Paqueta tries to hold the ball up in the corner without success. West Ham are doing everything they can to leave here with a draw.
Boniface sends a lovely pass through for Hofman to chase but Fabianski just beats him to it, kneeing the ball to safety.
77 mins: Kudus is fouled and takes a quick free-kick. Maybe heâs not received the message to slow things down.
Hofman and Boniface are on for Schick and Adli.
75 mins: Antonio, who looks a touch tired, is bundled over near the left touchline. Ward-Prowse whips the ball in but the goalkeeper claims easily.
Soucekâs pass hits the referee. Was it deliberate to stop the play and slow things down again?
Alonso is preparing Boniface and Hofmann.
73 mins: Kudus is showing some trickery and is fouled, allowing West Ham to waste a good 30 seconds.
Xhaka takes aim from 30 yards but it flashes past the post.
71 mins: WHAT A SAVE! Grimaldo chips a cross to Schick at the front post from where he flicks towards the top corner but Fabianski is equal to it and tips over.
69 mins: I suspect West Ham will need to send on some fresh legs soon. Johnson did well at Wolves, so I expect to see him. I am not sure who else would fit into this side at the moment. Ings might get a run up top â¦
67 mins: Grimaldo whacks a cross straight into Coufalâs head, leaving the right-back on the deck. That must hurt. He seems OK after treatment.
Hincapie and Tella are on, Frimpong and Stanisic off.
65 mins: The tables are turned and Leverkusen break. Frimpong gets into the area but his cross is blocked by the backtracking defenders. West Ham are extremely committed to the cause here.
63 mins: Tapsoba takes down Kudus inside the Leverkusen half. Ward-Prowse has a chance for a great delivery here ⦠it is decent but Leverkusen do well to clear.
61 mins: West Ham make it to the edge of the Leverkusen box where Paqueta is dispossessed.
Darke says Paqueta has âskills to burnâ. Is that a saying?
59 mins: Wirtz takes a lovely touch in the box and spins to shoot at Fabianski. The goalkeeper holds but the German is offside anyway.
Frimpong drives for the byline and pulls a cross back into space but Soucek is there to mop up.
57 mins: Adli is the latest to roll on the turf after being touched by a West Ham player. In fairness, it is not a great challenge because Emersonâs studs roll over the ball and onto the Leverkusen manâs legs. It is accidental but does not look great.
55 mins: Grimaldo wins Leverkusen a corner on the left. The ball reaches Wirtz in the box and he looks like he is about to shoot but he decides against it and West Ham recover.
53 mins: Paquetaâs arms brushes against Stanisicâs face and goes down. It is not a foul but it is right to check he is OK. It also allows West Ham a few moments of rest.
51 mins: Frimpong sends in a dangerous cross but there is no one there in black and red, allowing Coufal to clear.
49 mins: West Ham have barely had a kick in this half.
Tim Smith says: âI watched both games of Bayer vs Qarabag in the last round (limited, i.e. only option on TV in the US). While Leverkusen are unbeaten this season they looked far from unbeatable. Qarabag were up in both legs but killed themselves with sending offs and concession of late goals. Qarabag did take the game to Leverkusen though, which West Ham look unlikely to do (at least in this leg).â
47 mins: You will not be surprised to hear that the format is the same; Leverkusen are attacking and West Ham defending.
Kári Tulinius emails: âIn the tie to determine West Ham or Leverkusenâs future opponents, Roma lead by one goal to nil, after a header from Gianluca âNo Relationâ Mancini. The Giallorossi have looked slightly likelier to score, as Milan have been surprisingly dull, perhaps demotivated by their kit, which is the most boring possible version of the great Rossoneri strip.â
Second half
Here we go again!
Your other option tonight is Liverpool v Atalanta with Michael Butler.
Half time: Bayer Leverkusen 0-0 West Ham
Leverkusen have dominated possession but West Hamâs defence has been superb. Moyes will be very happy with this.
45 mins: One minute added on.
44 mins: Grimaldo whips in a corner from the left but it results in a dreadful shot wide. West Ham, understandably, take their time over the goal kick. They will be eager to see this through to half time.
Ian Darke keeps saying âGrimandiâ instead of Grimaldo and I keep thinking the former Arsenal man is in midfield. He is 53, so seems unlikely.
42 mins: Frimpong picks up a loose ball in the box and spins to shoot but his effort is deflected wide.
40 mins: Ward-Prowse whips in a corner from the left and Kovar comes to punch, getting enough on it and wins a free-kick for his troubles.
Down the other end ⦠Xhaka whips in a cross which Emerson gets confused by and turns behind for a corner with his thigh while trying to kick it the other way.
38 mins: Kudus whips in a cross but neither Antonio nor Emerson can get on the end of it. Both claim they are the victim of fouls but VAR disagrees.
West Ham are performing extremely well. They are operating with a low block and everyone is doing their role exceptionally.
36 mins: Antonio does great work in the final third to bundle his way through three Leverkusen defenders to make his way into the box and win a throw-in.
34 mins: Adli sends a dangerous low cross into the West Ham box but it is cleared at the near post.
Ward-Prowse is penalised for a foul on Palacios. West Ham very much letting Leverkusen they are there.
32 mins: Mavropanos is late on Wirtz and gives away a free kick 35 yards from goal. I am sure he will not mind too much.
30 mins: Fabianski makes another fine stop to keep things left, tipping a Schick shot across goal wide.
Wirtz is enjoying himself, drifting to wherever he thinks the ball will end up in the opposition half, always looking to create a chance. I have heard the hype around him so it is good to watch him and see what he can offer.
28 mins: West Ham string 20 passes together to take the sting out of the match but there is nothing at the end of it.
26 mins: West Ham have a throw-in which Coufal takes to Soucek who sends it out for a throw to Leverkusen. The visitors need to keep the ball better.
24 mins: Paqueta is late into a tackle on Wirtz, catching him on the top of the boot. He does not get a second yellow but he really needs to watch himself.
Stephen McCrossan asks: âCan you shed any light on what on Earth the nonsensical Robbie Savage was talking about there when he said that Antonio âpassed the ball to Kudus too earlyâ?â
I think he wanted Antonio to get further into the box before passing but who knows.
22 mins: A Leverkusen corner pinballs around the six-yard box but West Ham manage to scramble the ball away.
Adli is fouled by Paqueta who is booking, keeping him out of the second leg. A melee ensues and VAR take a look in case it is worthy of a red, which it is not. Paqueta still moans at the referee for some reason.
20 mins: Antonio is working hard to chase everything he can but it will be a thankless task.
Leverkusen are pinging the ball about and West Ham are struggling to cope with the speed of the passes. Grimaldo takes aim from distance, it looks set for the bottom corner but Fabianski makes a great save to his left.
18 mins: Shick rises highest to reach a cross but his header is a looping one and drifts wide.
16 mins: Leverkusen have a corner on the left which is played short but the routine does not work. This will be a long night of defending for the Hammers.
14 mins: West Ham have 10 behind the ball at all times and they are spending the majority of the match in their own box.
12 mins: We are looking at Leverkusen currently enjoying 81% possession. This is a training game of attack v defence. West Ham know what they have to do.
10 mins: West Ham counter thanks to a lovely touch and turn of pace from Antonio. He drives to the edge of the box and decides to pass to Kudus in space but his shot is straight at the goalkeeper.
8 mins: Leverkusen camp on the edge of the box and eventually get a chance when Stanisic shoots from 20 yards, it does not look like it will trouble Fabianski but Schickâs flick diverts the ball, making life tougher for the goalkeeper who saves.
6 mins: It is fair to say West Ham are taking their time over everything. Leverkusen, on the other hand, are trying to speed up the game. You can see what the intentions of both teams are already.
4 mins: Wirtz whips in a free-kick from the right to the back post but Coufal flicks it away and gets a headed into the back of his bonce for his troubles. The referee decides it is not a free-kick for some reason.
2 mins: A feel like the commentary team at not in Leverkusen for this, which is a bit underwhelming from TNT. Maybe I am wrong â¦
Onto the match ⦠It is certainly a back five West Ham as they look to contain Leverkusen in the early stages.
Kick off
Peep! Peep! Peep! Here we go!
Read some of the wonderful Karen Carney.
Jeremy Boyce emails: âWell, who would have thought the Europa League could have offered us one of the most intriguing ties of end of season Cup hi-jinks ? Unbeaten Leverkusen, virtually home and dry in the Bundesliga with the most loved and courted manager in Europe, v obdurate under-the-radar over-achievers West âAm and their loveable, friendly, all-smiles and free-flowing English footie equivalent. BL will obviously go for it, no need to rest players, likewise WâAU as they really need this to guarantee them some more exotic away trips next year. Itâs Dr Who v The Daleks. Whoâs holding the Sonic Screwdriver ?â
David Moyes: âAs high as it comes so far, so looking forward it. It will be a difficult game.
âWe want to be flexible during the game, we want to change and adapt. They alter as well so we need to move with them.
âIt happens in football, you get injuries and suspensions. We have to show what we have got, the players that come in have a chance to show what they can do.
âI want the players to be really professional, have a good understanding and play at a high level.
âThis is the time of the year you have to be in good form. If we win tonight, it will be the first time they have lost, so we have to look at it like that.â
I was at Molineux on Saturday and West Ham were utterly appalling in the first half. They cannot afford to start like that tonight.
There is not a massive amount on the bench for West Ham tonight. I am working on the assumption they will take a draw of single-goal defeat and get back to London.

Preamble
They might be unbeaten in the Bundesliga but Xabi Alonsoâs Bayer Leverkusen are yet to come up against the might of West Ham. Despite all the criticism of David Moyes and the style of football his side produce, they are seventh in the Premier League, not to mention in the final stages of the Europa League.
Unfortunately for West Ham they will be without Jarrod Bowen who suffered an injury in the the dramatic victory at Wolves on Saturday. They did not miss him too much after he went off at Molineux but facing the Bundesliga champions-elect is another kettle of fish.
Alonso could have the pick of jobs around Europe this summer but he has chosen to stay at Leverkusen and build on an absolutely fantastic season. He will fancy he chances of progressing in this competition, too.
Letâs hope for a cracker.
Kick-off: 8pm BST
