Borussia Dortmund v Hertha Berlin live updates - Belfodil converts from the spot to give Hertha the lead!

Guerreiro puts in a cross and Haaland latches on to it first time, but lashes his shot over the bar. That's the first time we've seen him in a dangerous position.

They've hung on at times, but they're defending well for what will be a massive result for them.

It's been a frustrating afternoon for them so far. They need just one goal to match their best single-season record.

He drives down the left hand side and forces a foul out of Pekarik.

Another dangerous free-kick for Dortmund...

Hertha will do well to hold the hosts off for the remainder of the game if it continues like this. Almost all of the action is happening in the visitors defensive third.

Another great piece of goalkeeping! He comes steaming out as Reus is threaded through, and does enough to see the German skew his effort wide.

Tousart lunges into the back of the England international and concedes the foul.

It's been a good battle between these two in the middle of the park.

Dortmund kick off the second half.

Hertha lead at the break!

Lotka literally smashes into the goalpost head-first as he made that acrobatic save.

He seems to be ok after a quick check.

The Hertha goalkeeper clatters the frame of the goal as he meets a dangerous Zagadou cross.

Hertha are sitting deep and are desperately trying to take this crucial lead into half time, but Dortmund continue to threaten.

Four additional minutes will be played at the end of the first half.

Dortmund's best chance of the half. Wolf gets down the right wing and finds Brandt inside the penalty area, who juggles the ball past two defenders before dragging his shot wide.

Guerreiro delivers a great ball from a set-piece out wide, but it's deflected behind for a corner.

He's a bit too casual as the ball comes back to him on the halfway line, and his weak header is picked up by Serdar, before Akanji makes up for his own mistake to win the ball back.

But a wave of Hertha Berlin players swarm around the ball on the edge of the box. Dortmund finding it hard to break them down.
