You've got to ride your luck. West Ham stayed calm and composed. And from the moment they got their goal they came out and enjoyed themselves.

And when you're on top you've got to take your chances.

What an end to the half from West Ham. Two goals in seven minutes have swung this tie completely their way.

They have one foot in the semis.

It's been brilliant from West Ham.

They just need to calm the minds, do their jobs and see it through until half-time.

West Ham in the ascendancy now.

Pablo Fornals tries to send Jarrod Bowen in on goal but his through-ball is cut out.

West Ham look like scoring from every set-piece!

A free-kick to the back post is met by Tomas Soucek, but his header back across goal flicks off Michail Antonio and diverts away from danger.

That is a huge moment for the Hammers.

They have had to dig deep to keep Lyon at bay here, with the home crowd growing in ferocity.

But they've pulled the rug on them.

Brilliant goal. I mentioned West Ham's threat from set-pieces. They have great height and great desire to get the ball.

Dawson attacks it from deep. It' a complete mismatch. Dembele the forward is marking him.

It's exactly what West Ham would have wanted and it sets this game up perfectly. West Ham are happy to play on the counter-attack.

Eintracht Frankfurt have doubled their lead, and it is an absolutely thunderous strike from Rafael Borre!

He finds a bit of space and runs towards the edge of the Barcelona box before unleashing a superb effort that fizzes into the roof of the net.

It's been end to end but despite Barcelona playing some neat stuff, it is the Bundesliga outfit who are on top and in control.

Oh, for a second Jarrod Bowen's deflected shot looks to be heading in. But the ball spins wide of goal for a corner.

Alf: This one's bubbling over nicely. West Ham settled down and offering a threat of their own. And I'm gonna stick my neck out here: One or two of these Lyon boys are dodgy at the back. You heard it here first.

This time Tomas Soucek wins the clearing header.

They have done really well under pressure at set-pieces so far.

Emerson is fouled wide left by Vladimir Coufal. Yet another dangerous Lyon free-kick...

Elsewhere in Europe, it's a great start for Rangers.

James Tavernier has put them ahead on the night at home to Braga to level the tie. It could have been even better with Kemar Roofe having a effort ruled out.

You can follow that game here.

There are plenty of shirtless blokes in the home crowd behind the goal that are more than happy to scream at Manuel Lanzini as he chips in a corner that Craig Dawson glances across goal and away from danger.

It is indeed swung in, but again Issa Diop is there, rising head to powerfully head away.

Barring his yellow card, Diop has had a solid first 30 minutes.

Romain Faivre is taken down by Ben Johnson near the left corner of the West Ham box. This will be swung in to the mixer...

It is a fascinating contest.

West Ham having to survive a thorough examination at the moment.
