Hamburger SV - Borussia Dortmund live updates

Hamburg looking to defend their lead at the start of this second half and hit Dortmund on the break. Schmelzer has a pop and shoots just wide.

Reus takes a tumble in the box and that looked very theatrical. No contact whatsoever. Mkhitaryan skews his shot wide.

Busy start from Dortmund at the start of this second half. They need it.

Piszczek and Castro the men coming on for Dortmund.

Back underway here as Ginter and Kagawa make way in a double substitution at the start of the second half.

And that is half time. Hamburg 2-0 Dortmund

Hamburg still quickest to those 50/50 challenges. Looking very hungry.

A minimum of three added minutes here.

Hamburg have been excellent but it’s a really strangely subdued performance from Dortmund so far. Not seen them play this poorly for a while. Insipid.

That is the former Spurs player’s second goal of the season. What a story being written here.

GOAL HAMBURG! And it’s Holtby who latches onto a simple pass from Muller to slot home past Burki. All stemmed from a loose pass from Ginter.

Can’t think of too many chances for Dortmund so far. Just the one shot from Reus, comfortably saved.

More great defending from Sakai. The cross comes in but it’s a good claim by Adler.

All about game management now. Crucial that the home side go into half time without conceding now.

Mkhitaryan plays the corner short and there’s some pinball in the box before Jung hacks the ball clear. Hamburg survive again. Defended well in the end.

Another swift break from Aubameyang, sprinting 40 yards with the ball but a giood challenge from Sakai forces a corner.
