The substitute goes into the book for dissent after full-time.

Couto is unable to continue, and so is replaced by 21-year-old Lührs, who is making his first appearance at Signal-Iduna Park.

The right-back has taken to the floor with an injury concern, and the medical staff are coming on to provide treatment.

Two shining lights in Gittens and Reyna come off in place of two more talents, Wätjen and Duranville.

A late challenge by Reyna on Geiger sees the USMNT international awarded a yellow card.

Guirassy steps up and strikes the ball towards goal, electing to go the same side as Baumann is stood, but the effort lacks power and is at a comfortable height for the Hoffenheim captain.

Guirassy draws a foul just outside the area on the left-hand side. There are plenty of Dortmund players interested in taking this one on.

Schlotterbeck may have been a doubt for this game due to injury, but you wouldn't have been able to tell looking at that challenge he just put in on Bruun Larsen. Intensive stuff from the Germany international.

Groß, currently on a yellow card, makes way for Marcel Sabitzer in a like-for-like switch.

Cutting in off the right once again, Adeyemi feints the shot numerous times before finally sending a left-footed strike across goal, and it bends just wide of the target.

Bensebaini switches the ball to Adeyemi on the right, who drives at the Hoffenheim defence before cutting in from the right and firing a left-footed shot towards goal. It flashes just wide of the target, but the returning winger is looking sharp.

Reyna scores on his first Dortmund start for 14 months. The midfielder, who had a loan spell at English club Nottingham Forest last season, has taken his chance in the starting XI with a quick-fire goal after the break.

Reyna breaks the deadlock! After a Gittens cross into the box is headed clear by Nsoki, it falls to the American, who chests it down before blasting it into the top right corner to give Dortmund the lead!

...and they've made a change at the break. Adeyemi has returned to make his first appearance since 1 October. He comes on for Beier.

Nmecha fouls Moerstedt during an aerial duel and subsequently goes into the book.

Gittens sends another cross in towards the back post, seeking out Guirassy, but the ball is just too high for the striker and goes behind for a goal kick.

Groß crosses in from a corner, but it comes straight back to him from a Hoffenheim clearance at the near post. The second cross is much better and flies through the crowd without hitting a Dortmund player, but is still goal-bound and forces a good save out of Baumann.

Reyna chips a great first-time ball into Guirassy on the edge of the box, but the striker cannot quite take it in his stride as it rolls back through to Baumann.

Guirassy quickly changes direction with a good first near the penalty spot, and goes to ground after drawing the foul from Chaves. The referee does not hesitate before pointing to the spot.

Groß goes into the book after a late challenge on Stach.

The youngster cuts in off the left and skips past three Hoffenheim players before sending a lofted ball through to the back post, where, unfortunately for him, there are no takers.

Groß whips the free-kick in towards the danger area, and Schlotterbeck manages to stretch a foot out to divert it towards goal, but it flies wide of the left post and into the side netting.

After initially slipping to concede possession to Gendrey in the Dortmund half, Gittens get back and gets his foot on the ball once again before drawing a foul to relieve the pressure.

Reyna slides it through to Gittens on the left side of the penalty box. The Englishman looks to square it to Guirassy, but a Hoffenheim player intervenes before it ends up in the arms of Baumann, putting an end to the attack.
