We go again in Spain. Erik ten Hag needed to do something and has made two changes. Marcus Rashford replaces Jadon Sancho and Luke Shaw is on for Aaron Wan-Bissaka, which means Diogo Dalot moves over from left-back to right-back.

Back under way in London. A big 45 minutes for West Ham.

Manchester United have failed to score a first-half goal in seven of their 12 games in the Europa League this season.

Iain: If ever there was a half of football which highlighted how important Fernandes is to this United side it's this one. Forget his decisive passing ability & composure on the ball for a second, his work rate off the ball goes largely unnoticed. We look ragged without him.

Michael: Bruno Fernandes is United's engine, love or loath him, he puts the spark into them.

Bono has looked nervous at times and they've barely tested him, take a chance. At the moment they are not shifting it quick enough and giving themselves that opportunity.

Plenty still in the balance in Europa League action tonight.

Juventus hold a narrow 2-1 aggregate lead over Sporting Lisbon with the teams level at 1-1 at half-time.

Roma and Feyenoord are still 0-0 which means Jose Mourinho's side trail 1-0 on aggregate.

Bayer Leverkusen are 2-0 up against Union Saint-Gilloise and lead 3-1 on aggregate.

In the Europa Conference League, Nice lead Basel 1-0 at home which means they have a narrow 3-2 aggregate lead.

Fiorentina and AZ Alkmaar are both through to the semi-finals.

A fairly basic goal brought West Ham level and the home side finished the half on top.

David Moyes was complaining to the fourth official at half-time.

I suspect he feels his side should have had a penalty.

Manchester United have been masters of their own downfall. They've gifted another goal to Sevilla and it was scratched off by a kneecap.

Sevilla are 45 minutes away from the semi-final after Youssef En-Nesyri's goal.

The hosts thought they had got the second, but Lucas Ocampos was denied by a very tight offside just before he got the ball.

The good news for Manchester United boss Erik ten Hag is his side can't do any worse in the second half. They've been really poor tonight and heading out as it stands.

Gent probably the happier of the two sides to hear the half-time whistle. A rollercoaster half for West Ham, who started and ended it well but Gent have caused them problems. All to play for.

There was a VAR check.

Said Benrahma's header from the throw-in did hit Matisse Samoise's upper body but it's been deemed above the arm.

Ivan Rakitic volleys at goal, brilliant technique, but it bounces off the chest Casemiro and goes over the top. Superb defending.

Gent are clinging on for the half-time whistle. It's really opened up with West Ham pushing desperately for a lead but they're leaving themselves a little vulnerable at the back. There's appeals for a penalty here too as a West Ham throw-in is blocked, with suggestions it was handball.

Richard: Self-destruction. Self-implosion. We were 2-0 up in this tie and now ALMOST 4-2 down. Absolutely embarrassing. We're handing this to Sevilla on a diamond crusted, platinum platter. Embarrassing from every red shirt.

Declan Rice's through ball doesn't look like it will come through to Said Benrahma but he doesn't give up and gets lucky, almost helping it on to Michail Antonio. He wins a corner instead and from it Rice's powerful effort is blocked.

So a lucky let-off for Manchester United. The video assistant referee comes to save them. But this has been an awful first-half performance from Manchester United.

West Ham have got the upperhand at the moment and want a second goal before half-time.

Michail Antonio wins a throw-in but Said Benrahma can't cut it back on the byline afterwards.
