Michy Batshuayi helped ensure Marco Reus' return ended in triumph as he continued his fine start to life at Borussia Dortmund with the opening goal in a hard-fought 2-0 Bundesliga win over Hamburg.

Belgium international Batshuayi hit a debut double in the 3-2 victory against Cologne last week and he made it three goals in two appearances with a poacher's finish less than four minutes into the second half.

After the €63.75million departure of the prolific Pierre-Emerick Aubameyang to Arsenal, the on-loan Chelsea striker's form and Reus' first appearance since last May having been sidelined through anterior cruciate ligament damage will help raise sprits at Signal Iduna Park.

Reus showed no signs of rust during the 71 minutes of his comeback, but - despite an attacking line-up also including Andre Schurrle, Christian Pulisic and Shinji Kagawa - Dortmund found the going tough against Bernd Hollerbach's well-drilled side.

Batshuayi made the breakthrough with their first shot on target and he celebrated his first home goal for the club with a somersault celebration that echoed one of the departed Aubameyang's favoured ways of marking a goal.

Pulisic missed a glorious chance to make the points safe but substitute Mario Gotze grabbed a second in injury time to extend Peter Stoger's unbeaten record at the helm to seven Bundesliga matches and lift BVB to third with a 500th home victory in the division.
