The hosts have the first chance of the second half as Mikkel Desler jinks one way and the other and lashes a shot wide.

A reminder how important three points tonight would be for Brighton.

Holding on to this lead in Amsterdam would put Roberto de Zerbi's side on seven points from four matches, leaving them in a good position to progress from the group stage.

With Marseille playing AEK later, the Seagulls are top of Group B in the as-it-stands table.

A big 45 minutes (plus stoppages) coming up

Second half under way.

Mohamed Salah, Trent Alexander-Arnold and Dominik Szoboszlai replace Kostas Tsimikas, Wataru Endo and Ben Doak.

Liverpool are bringing on the big dogs.

Ajax are yet to win in the group stages of the Europa League this season, drawing two and losing one.

And it's not looking good so far tonight.

The Dutch giants last started a major European campaign with no wins from four matches in the 2015-16 Europa League.

It's a bit nippy at Villa Park as the stewards and security team slowly open the stadium up to supporters.

Even after a setback at the weekend - a surprise 2-0 loss to Nottingham Forest - most home fans had a spring in their step walking to the ground, and are expecting a big win tonight after Villa thrashed AZ Alkmaar 4-1 in the reverse fixture two weeks ago.

After two wins and one defeat, Unai Emery's Villa are second in Group E and need two more victories from their final three group matches to guarantee reaching the knockout stages.

But AZ have won 11 of their 17 matches this season across all competitions, and are second in the Eredivisie.

Last season they made it all the way to the semi-finals of this tournament, where they fell to eventual champions West Ham.

The next corner comes to nothing for Brighton and that will be that.

Time for a stroopwafel.

Brighton still pushing for another before the break.

A corner won by Simon Adingra is headed over the bar by Jan-Paul van Hecke with the aid of a deflection.

Time for another corner...

Not really been any serious chances other than the one which Ansu Fati stuck away for the only goal of the game.

Hold on... here's another. Right on cue.

With the first half heading into three minutes of stoppage time, Simon Adingra bursts into the Ajax box and shoots from a narrow angle on the right.

The size 10 boot of Ajax keeper Diant Ramaj keeps the ball out.

Niklas Schmidt had a shot saved by Caoimhin Kelleher just before half-time.

Huge cheers from the home fans as the half-time whistle goes with Toulouse leading Liverpool.

One minute added on as Toulouse fail to create a chance from their corner.

Les Violets try to add a second before the break but Mikkel Desler's kick is neither cross nor shot and it's blocked.

TFC win a corner though.

Brighton skipper Lewis Dunk, named earlier today in the latest England squad, sits down on the grass and then has this groin issue assessed.

The Seagulls have already been forced into one change after losing James Milner earlier.

Dunk looks fine, though, and quickly jogs back into the action.

Oh no, this is not a sight which Brighton want to see.

Skipper Lewis Dunk stretches to collect the ball and immediately winces before holding his groin.

He's tweaked something.

Not Kostas Tsimikas' night so far. Liverpool's second-choice left-back swings a cross straight out of play.

Brighton have spent the past few minutes taking the sting out of the Ajax revival.

Keep the ball, lads. Slow it down.

I really need to stop saying really in every entry.

Wataru Endo really needs to watch himself. The Liverpool midfielder slides in on Cristian Casseres and brings him down. He's already been booked and he could have been sent off there.
