The BVB boss remained calm in the face of a heavy loss to HSV, but conceded that Robert Lewandowski's dismissal gave the visitors a crucial momentum
Robert Lewandowski put the German champion in the driving seat early on, but the striker was later sent off, with Artjom Rudnevs' double and two goals from Heung-Min Son condemning BVB to a costly loss.
Speaking after the match, Klopp opted not to criticize his team and instead highlighted the high-octane nature of proceedings, although he did admit that the dismissal of his star man helped Hamburg seize the momentum that eventually proved decisive.
"The game had a lot of stories," Klopp told reporters. "Hamburg, from the outset, came into the game, and after going 2-1 up, the action was hectic and wild in light of Robert Lewandowski's dismissal.
"It was an unhappy ending for us. Our strength and morale diminished against a strong Hamburg."
