There was nothing the keeper could have done to stop Lam's sensational strike or Westermann's close-range header. Other than that, he was rarely tested and had a largely comfortable evening between the posts.
His marking from set pieces was not always great as after allowing Lam to cut inside him too easily for HSV's first, he then let Westermann get away from him for their equaliser. He was withdrawn on the hour mark, much to his dismay.
Was relentless on the left flank as he chased up and down to help offer as much support to his side's forwards as possible. He put some decent crosses into the box but an intelligent quick free kick saw him assist Aubameyang for the opener.
Hit the bar with a header in the first half which would have given his side the lead. Ensured that the BVB defence retained some respectability while Subotic was on the pitch but was far more assured alongside Sokratis.
Put in a fairly competent performance as the makeshift right-back. He was perhaps out of position as Lam got HSV back in the game, but he was more reserved thereafter. He supported Aubameyang effectively in the second half.
Had a bit of a sloppy start to the game with some misplaced passes but soon asserted himself on the action. He regularly pushed up to support the forwards and got some efforts away on goal. His cross was headed home by Lewandowski for his second.
Proved a real threat in the hole behind the striker as he linked up seamlessly with his new team-mates. He worked Adler early on but scored with his next effort, which he rolled into the bottom corner. He was so composed on the ball and set up Aubameyang for his second.
Worked hard in the middle to stop Van der Vaart from finding space in which to pick up the ball. Whenever HSV looked to probe through the middle he was on hand to put in a tackle and disrupt the play.
Occupied the centre-backs to good effect and forced them all to watch him closely. He was impressive with his back to goal and his assist for Mkhitaryan to get BVB's second was stunning. He showed great composure to net his side's fourth.
The Germany international shrugged off the illness picked up whilst on duty with the national team to put in a great performance. His dribbling was exquisite and scored a deserved goal late on following a flurry of superb interlinking play with his team-mates.
Used his pace to great effect, continually running in behind the HSV defence and getting into threatening areas. He opened the scoring for his side before adding a vital second to put his team 3-2 up. He was a constant threat to the opposition.
Made a couple of decent saves early on but was at fault for the opening goal as he let Aubameyang's strike slip past him at his near post. He made a number of great stops throughout and was unfortunate to have six goals put past him.
Failed to supply enough width on the right flank for the visitors. He only put one decent cross into the box in the first half and defensively he allowed Schmelzer far too much freedom. His poor clearance resulted in Reus' goal.
Struggled to get to grips with the three-man defence and was either to close or too far away from Djourou. He resorted to hopeful long passes that led nowhere before being withdrawn at half time.
Made some well-timed challenges during the early exchanges but was completely outpaced by Aubameyang as he raced through to open the scoring. He got a goal back for his side but was all at sea as Lewandowski headed in the sixth.
A rather clumsy performance from the Switzerland international as he was far too quick to dive in and commit to the challenge. He failed to make the most of his superior physique as he was held off by Mkhitaryan as he scored BVB's second.
R. van der Vaart
Found it difficult to get himself in possession inside the BVB half and seemed reluctant to drop deep to pick it up. He put a few good balls into the box from free kicks, one leading to an assist for Westermann, but on the whole he struggled for creativity.
The midfielder was hardly involved in the game and he struggled to make any kind of mark on proceedings. For some reason he did not make himself available for the ball and therefore his team struggled in midfield.
Failed to track back and help protect against Aubameyang's pace in the first half. He undoubtedly scored the goal of the game with an absolutely brilliant strike but looked shaky when moved back to left-back in the second half.
Screened the defence poorly and was overly combative, finding himself overrun at times. His inability to pass the ball out competently from the back led to a disjointed midfield performance from the visitors.
It just was not the Cameroonian striker's night as he failed to hold up the ball effectively. His touch let him down on most occasions and his only real input was to move the ball out to the left for Lam to score Hamburg's first.
Was unable to use his electric pace as HSV failed to supply the strikers with enough service. He did not manage to get into an area in which he could test Weidenfeller as the Hamburg strikers looked toothless.
