Aron Donnum really did catch Kostas Tsimikas half asleep there with his tackle.

We said we were just waiting for something to happen.

It was poor from Tsimikas, just fell asleep and allowed the opposition to get into the game.

Caiomhin Kelleher has no chance with the deflection, flies off Jarell Quansah's leg into the net.

A very unlikely lead for the home side, and not a good look at all from the Liverpool left-back.

Ajax, who like Brighton want to dominate the possession, are starting to play with a little more energy and intent.

But their patterns of attacking play are lacking fluidity. Fair to say it has been relatively comfortable for Brighton defensively.

Nice footwork from Harvey Elliott and he curls a shot in from the corner of the box which hits the first man.

A soft one. Joao Pedro is booked for a foul near the halfway line and looks incredulous when he sees the referee pull out the card.

Moments later, the Brighton forward tries to take out his frustration by lashing a shot goalwards. Dragged it wide.

Liverpool midfielder Wataru Endo catches Thijs Dallinga and receives a booking.

Ajax are getting slightly desperate with these penalty shouts.

Another goes up when Lewis Dunk challenges Brian Brobbey. Firm but fair challenge.

With LASK beating Union SG in this group, a Liverpool win would send them straight to the last 16 (rather than the play-off round before that).

Whistles all around the Johan Cruyff Arena - well, in the home areas at least - when Kristian Hlynsson's cross hits Pascal Gross.

They reckon it has hit the Brighton man's left arm.

Referee Nikola Dabanovic does not agree, indicating it hit him on the side.

No penalty.

Toulouse goalkeeper Guillaume Restes, who is only 18, flaps at a cross but makes amends with a good save from Ben Doak's volley.

Roberto de Zerbi uses the brief break for Joao Pedro to get checked out by giving a few pointers to midfield duo Billy Gilmour and Mahmoud Dahoud.

The Brighton boss will happy with his side's application so far.

Brighton fly forward through their excellent ball carriers and Joao Pedro, who has scored in each of his side's Europa League games, tries to finish off the move by nipping ahead of Ajax keeper Diant Ramaj.

Ramaj wins the race to grab the ball, using his weight to stand tall and let the Brighton forward bounce off his frame.

Pedro looks to be winded.

Toulouse's best chance of the game. Niklas Schmidt swings in a cross which a sliding Gabriel Suazo sends wide at the back stick.

Toulouse haven't tried to be progressive at all have they?

They have just sat back and tried to do something on the counter attack - probably a result of the reverse scoreline at Anfield the other week.

As the home team, and the team that need to win really, they have been disappointing so far.

Ajax have edged possession in the opening 25 minutes but don't really have the creativity to supply striker Brian Brobbey.

A cross from the right is aimed towards Brobbey.

However, Brighton's defence are well organised and Jan-Paul van Hecke is perfectly positioned to clear.

And that could start a Brighton counter...

Luis Diaz hammers in a shot from 25 yards, it's low and central and Guillaume Restes gathers at the second attempt.

Ben Doaks turns 18 in two days' time, in the week I turn 40. Great.

Brighton are playing with pace and purpose as they only know how to.

The visitors are pressing sharply - like they did to hustle Vos into the mistake for the goal - and more pressure results in Kaoru Mitoma driving forward from midfield.

The Japan star tries to thread a ball through to Ansu Fati, but it lacks the precision needed to allow the goalscorer to line up a shot.
