Leeds centre-back Liam Cooper picks up a caution for a strong challenge on Tomer Hemed.

The visitors have been on top in the last few minutes, but are lacking a cutting edge.

Mustapha Carayol bursts into the Albion box and the ball falls to Souleymane Doukara, but his short on the turn is well wide.

Brighton keeper David Stockdale is finally called into action, comfortably gathering a long-range attempt from Lewis Cook.

Another Leeds set piece from outside the box, and Alex Mowatt goes for goal again.

He goes for the far post with his left-footed effort but it is high and wide.

Albion keeper David Stockdale is still to make a save.

Another Brighton player in the book.

Leeds winger Lewis Cook drives at the heart of the Brighton defence and is tripped by Connor Goldson.

Leeds boss Steve Evans remains in his technical area looking for a way back into the game.

Simon Tinsley: Once again individual defensive errors mask the true problem at Leeds. Lack of any attacking threat.

Dean Plumley: Leeds knew what the problems were when the transfer window was open and did not address any of them, my heart is breaking.

Darragh Culhane: The first ever Leeds game I went to watch they were 3-0 v Brighton and came back to 3-3, don't think today will be the same.

A last-gasp challenge denies Brighton their fifth.

Sam Baldock was played through on goal by Dale Stephens and only a last-gasp challenge from Lewie Coyle sends the ball behind.

The striker was just about to pull the trigger from six yards out.

Leeds threaten from another free-kick.

This time it's Alex Mowatt on set-piece duty and his effort flicks off the top of the wall and goes narrowly over the bar.

Leeds get a free-kick after Lewis Cook is body-checked by Connor Goldson.

It's about 30 yards out from goal, just to the left hand side.

Souleymane Doukara attempts an ambitious shot, but it hits the bottom of the wall.

Brighton carve out their first chance of the second half.

Jamie Murphy cuts in from the right and his deflected effort just eludes Anthony Knockaert and Dale Stephens in the box.

The Seagulls have the bit between their teeth.

Leeds get the second half under way. Can they mount an incredible comeback in the second half?

I would love to know what Steve Evans told his charges at half-time.

Leeds winger Mustapha Carayol is on for defender Scott Wootton at the break.

The second half is almost upon us.

Will Brighton look for more goals in the second half in a bid to boost their goal difference? They have the lowest goal difference of the sides in the top four, with Burnley, Hull and Middlesbrough well ahead.

Brighton are looking to reach the Premier League for the first time, having last played in the top flight in 1982-83.

The Seagulls were beaten play-off semi-finalists in 2012-13 and 2013-14.

Gary Birch: I will support the Whites until the end but these players need a reality check. No passion or pride to wear the kit.

Richard Mortimer: LUFC keep finding new lows when you think it can't get any worse. Evans'll be gone by the morning if it's the same in 2nd 45.

Lee Parkinson: I've followed my beloved Leeds through thick and thin and tonight its, well... heartbreaking.

Phil Durrant: Last game BHA score more than three in a league game for over a year, now twice in a few days! Promotion push back on track.

Thomas Broadley: Should compensate the superb travelling fans. What an absolute disgrace.

Matt Price: Leeds making Brighton look like Barcelona.

Ian K: 4:0 (so far!) We've had this coming for a while now. Limited options up front and some maybe seeing season out. Not good.

Chris Gibson: Time for Evans to go.

Do you agree with Chris? Or is it just one of those nights for Leeds? Have your say using #bbcfootball.

That was a blistering 10-minute spell from Brighton in which they went 3-0 up after Tomer Hemed got the ball rolling from the penalty spot.

Albion have scored four goals for the second time this season, following up their 4-0 win at Bristol City last time out.

The Seagulls look like they will move to two points of league leaders Burnley, unless Leeds can mount an impressive comeback.

Referee Peter Bankes blows the half-time whistle and puts Leeds out of their misery.

Leeds have not tested home goalkeeper David Stockdale in the opening period.
