Reyna hits a free-kick down the throat of Flekken. Dortmund want six...

Another beauty of a goal for Dortmund. Bynoe-Gittens teases the Freiburg defence, before shifting the ball inside. Guerreiro touches it off for Reyna on the edge of the area, and the American nonchalantly places a first-time finish into the corner. BVB have been superb today!

As things stand, Bayern, BVB and Union - pegged back by Mainz - are level on 37 points.

Dahoud's on for Wolf in a further show of Dortmund's strength in depth.

Bellingham and Reus get the hook, with three points surely in the bag. BVB also have a midweek DFB Cup game against Bochum to think about. Malen and Reyna are on. No wonder Terzic has been talking up this Dortmund bench as the club's "best in years".

Dortmund extend their lead. Guerreiro is the provider with a smart inside pass for Brandt. He drives at the Freiburg defence, before unleashing an unstoppable swerving drive into the bottom corner. The curve on that was really something!

Dortmund are in complete control as Bellingham sends a cross just beyond Haller's reach. If they can see it out, it'll be a fourth straight Bundesliga win for Terzic's men.

What a moment! Haller sweeps over a cross that's put behind, just as Guerreiro was about to pull the trigger. Brandt's ensuing corner is cleared, but he keeps the chance alive by feeding Guerreiro. This time the cross is right on the money, and right onto the head of Haller. That's his first Bundesliga goal for Dortmund and first in competitive action following his recovery from testicular cancer, and he's done it on World Cancer Day. As the jubilant celebrations ease off, the Ivorian looks down the camera whilst pointing to the "f*** cancer" message on his boots. Incredible.

That didn't take long! BVB play a short corner across the box to Adeyemi. He lays it off to Bellingham, who back-heels it back into the Germany international's path. He wriggles, jiggles and digs out a shot that nestles into the far corner. Superb move, and a fine finish!

Adeyemi, on the receiving end of a good few fouls already, is penalised for impeding Kübler. Grifo's right-wing free-kick is flicked on, but comes to nothing as Kyereh, off balance, blazes high and wide.

Süle smashes in an effort from range that Flekken does really well to push behind. Brandt's near-post corner is only half cleared, with former Freiburg defender spinning on a sixpence to swipe in from the most acute of angles. It had been coming!

Bellingham hits the deck just inside the Freiburg area. He was sandwiched between Doan and Günter, but the referee suggests the BVB teen went to ground too easily.

Dortmund with some lovely interchange involving Brandt and Wolf. Bellingham takes aim from 18 yards, but it's on his weaker left foot and he drags the ball wide.

Really smart play from Dortmund as Wolf drives in off the right and finds Adeyemi in the box. He helps it on to Guerreiro, who lashes narrowly wide of the far post, with Flekken rooted to the spot. BVB mean business.

Unnecessary from Guerreiro. He goes straight through the back of Höler, who was going nowhere.

Haller does really well with his back to goal, under pressure from a Freiburg shirt. He lays the ball off for Guerreiro, who threads a pass into the box for Brandt before a defender makes a crucial block.
