HAALAND SECURES THE WIN!
It's a goal right at the death to secure all three points for Haaland.
We're into three minutes of added time here.
SCHICK HEADS WIDE
He's on the end of Halstenberg's cross, but can't keep his header on target here.
Schulz and Zagadou are on in the final minutes to sure up Dortmund's defence.
ANGELINO FORCES A SAVE!
A fantastic pass into the Dortmund box from Nkunku sends Angelino into the box and he goes to lob Bürki with the Dortmund 'keeper off his line, but the BVB No.1 makes a fine save.
INTO THE FINAL 10...
Sancho is on for Dortmund, but Leipzig are on top...
TIME TICKING ON
Dortmund may look good for now, but there's plenty of time for this game to change and the away side will have some concern that it's still only 1-0. Sancho is getting ready to come on and look to get another goal of the Dortmund scoresheet.
The Dortmund midfielder is now suspended for the final game of the season against Hoffenheim. His season is over.
Dortmund aren't forcing the ball forward when they have it here. Happy to stay patient and keep Leipzig working to win it back.
Werner and Kampl come off, replaced by Nkunku and Haidara. That's Werner's final home game in the Bundesliga over for Turbo Timo.
Angelino's volley-cross is headed down by Olmo to Schick. He can't control but the ball falls to Forsberg, and his shot is blocked by Hummels.
MOREY HAS A GO
Time and space opens up for the Spanish full-back making his first start for Dortmund, and his shot from 20 yards forces a good save low down from Gulacsi.
NO WAY THROUGH
The home side still keeping on top here but they're finding difficulties in opening up the Dortmund defence. Werner and Schick struggling to get touches of the ball with the away side's shape incredibly compact without the ball.
GETTING ON THE BALL
The home side have controlled the possession in the last five minutes or so and are beginning to take more control of the game. Still, Bürki has only had to make one save so far.
Angelino is the latest Leipzig man in the book after a foul on Morey.
More fluid football from Dortmund and Haaland almost finds Reyna in the box with a perfect pass, but the American's touch lets him down. Dortmund will want to make sure they make the most of their pressure with the scoreline still just 1-0...
The second yellow card of the day for the home side goes to former Dortmund man Kevin Kampl.
HAALAND HITS THE BAR!
What an effort. Hummels plays him in behind and his pace takes him away from Halstenberg. He smashes a shot at the near post and Gulacsi somehow tips it onto his own crossbar and the ball bounces away to safety.
OLMO HITS ONE
The substitute goes for goal from range but gets it all wrong, dragging his shot wide of Bürki's goal. You can tell the Spaniard has an eye for goal, though.
A yellow card for the American after a foul on Mukiele, his second booking of the season.
HUMMELS STOPS WERNER
A mistake in midfield from Julian Brandt is pounced on by the home side and Werner is played a through ball. Hummels stays with him though and puts in a good challenge to halt the attack.
HUGE CHANCE FOR MOREY
Dortmund almost two goals up immediately in the second half with Haaland sent away towards the Leipzig box. He plays it across goal to Morey who slides a left-footed shot goalward, but he doesn't get the desired connection and hits his effort wide with Gulacsi closing him down.
The second half begins in Leipzig with Tyler Adams on at the break for Lukas Klostermann.
The Portugal international curls a free-kick at goal from the right corner of the box. Only half of the Leipzig wall jumps, and the ball goes through it before bouncing wide. Gulacsi not happy with his teammates for what could have ended in a second goal for Dortmund.
PATIENCE IS KEY
Dortmund have enjoyed almost 60 percent of the possession here in the first half. A feat in itself with them playing away at Leipzig. The away side have completed 94 percent of their passes.
GOOD CHANCE FOR WERNER
Leipzig finally break through the Dortmund defence with Werner played in behind. He reaches a through ball in the Dortmund box, sliding a left-footed shot at goal. But Bürki - fresh from signing his new contract until 2023 yesterday - makes a solid save.
The Spanish playmaker - fresh from a brace against Hoffenheim last weekend - is on for the injured Sabitzer.
Both sides go off for a drink with the sun out in Lepizig. Meanwhile, Sabitzer has left the pitch and a substitution will be made.
Leipzig's captain is off the pitch taking treatment to his right knee at this moment in time. At first look, it did not seem promising for him.
A NEW CLUB RECORD
Haaland's goal is Dortmund's 83rd in the Bundesliga this season. A new record for the team in the German top-flight.
WHAT A GOAL!
They've been doing it all game so far and Dortmund produce an outstanding team goal. Hummels sends Brandt away down the right. He cuts it into the box for Reyna who has the vision and composure to open his body and pass to Haaland in front of goal, and Haaland takes one touch before slotting it home past Gulacsi.
DORTMUND IN THE GROOVE
Whether it's long balls over the top from Hummels or intricate passes through midfield, Dortmund are having no trouble finding ways through the Leipzig defence so far. The home side looking to get back on the ball now, but it's been a half where Dortmund have been on the front foot.
HAZARD FORCES A SAVE
Another long ball over the top from Hummels - with the outside of his boot, no less - sends a forward away in behind Leipzig's defence. It's Hazard on it this time and he smashes a shot at goal, but Gulacsi makes a good save at his near post.
The striker is cautioned for a foul on Witsel in midfield.
UNDER PRESSURE STILL
The home side are having to work with very little here, especially in the last 10 minutes or so. Dortmund are patient in possession and have cut-out every attempted Leipzig counter in this phase of play.
HUGE CHANCES FOR HAALAND
Dortmund are continuing their outstanding start to this game as Hazard skips past a defender into the Leipzig box. He then touches the ball beyond another for Haaland around the penalty box, but Gulacsi makes a big save. A minute later and Haaland's shot is saved again by Gulacsi!
HAZARD HITS ONE!
More fantastic build-up from Dortmund as Hummels sends Guerreiro away down the left. He cuts it back to Hazard this time on the edge of the box, but he drags his shot narrowly wide. A great start here from the away side.
Dortmund already showing a major improvement from their performance in the defeat against Mainz. Good patience on the ball, and fluid pass-and-move play through the pitch. Leipzig are on the defensive for now.
HAALAND SO UNLUCKY
Beautiful build-up from Dortmund and Hazard's cut-back to the box finds Haaland in space. He goes for goal with a powerful strike which is on target, but Reyna accidentally blocks it.
SCHICK FIRES WIDE
First chance for the home sie as Forsberg sends a lovely through ball between two Dortmund defenders and into their penalty area. Schick is on the end of it and goes for the near post, but his shot flies past the goal.
ALMOST FOR HAALAND
Morey sends an outstanding ball forward towards the Norweigian striker from the right wing. He's almost in on goal, but Upamecano challenges well and puts the ball back towards Gulacsi in the home side's goal.
SLIGHT KIT CHANGE
As there is some yellow on the socks of Leipzig's new kit, Dortmund have been forced to wear socks in different colour today. They've gone for black to go with their yellow shorts and yellow shirt.
AWAY WE GO!
The ball is rolling in the Leipzig sunshine.
IT'S ALMOST TIME
If you're not ready yet, settle into your seats and grab your food and drinks for what is set to be a blockbuster in Leipzig. Just five minutes to go until kick-off.
A WIN SEALS SECOND
With a three-point lead ahead of their hosts, Dortmund know that victory today - with only one game to play after this - will secure them second place in the table. Dortmund are unbeaten in their last four meetings with Leipzig (W2, D2).
WERNER VS. SANCHO
Sadly, only one of the Bundesliga's deadliest attackers is starting today with Jadon Sancho left on the bench. Only Bayern's Robert Lewandowski (31 goals, three assists) has had a direct hand in as many Bundesliga goals this season as Leipzig top scorer Werner (26 goals, eight assists). Dortmund counterpart Sancho is one behind (17 goals, 16 assists).
LEIPZIG'S LOVE AFFAIR WITH FACING BVB
Leipzig celebrated their first ever Bundesliga win against Dortmund in September 2016. They did the double over them that season, but haven't beaten the Black-Yellows since. Head coach Julian Nagelsmann has won only one of eight meetings with Dortmund, but is unbeaten in his last four (W1, D3).
BOTH LOOKING TO BOUNCE BACK
It was a disappointing midweek for both of these sides, who were in action on Wednesday evening. Dortmund suffered a surprise 0-2 defeat at home to relegation-threatened Mainz while Leipzig conceded two late goals to draw at home to another relegation-battling side, Fortuna Düsseldorf. With only two games left to play and three points between the two sides, both will be desperate to return to winning ways today. A win will secure second place for Dortmund.
NEW KIT ON SHOW FOR LEIPZIG
The home side will be rocking their new threads for the 2020/21 season. Head over to the club's official social media channels to take a look at the new kit, which of course sticks to Leipzig usual main white colour with red trimmings and also some yellow included in the new shirt.
REYNA MAKES FIRST START
Having been in line to start in the Revierderby against Schalke, Reyna pulled up with a muscular injury in the warm-up and has been waiting to make his first start in the top-flight since. Today is the day for the 17-year-old who comes in to start ahead of Jadon Sancho in a vital game for both sides, with each willing and able to finish second behind champions Bayern Munich.
LEIPZIG TEAM NEWS
The home side make four changes from the side which were held at home by Fortuna Düsseldorf. Konrad Laimer is ill, while Tyler Adams, Dani Olmo and Christopher Nkunku all drop to the bench. For them come in Nordi Mukiele, Emil Forsberg, Dayot Upamecano and Patrik Schick.
