Serhou Guirassy scored the winner with seven minutes remaining to send Borussia Dortmund past St Pauli 2-1 at home in the Bundesliga on Friday. Leading by a goal after Ramy Bensebaini's excellent first-half header, Dortmund were pegged back by a long-range effort from Eric Smith to level things up with 12 minutes remaining. Guirassy stepped up in the dying stages, heading in an inch-perfect Jamie Gittens cross to put Dortmund back in front.

The Guinean, who joined Dortmund in the summer, now has 12 goals in his past eight games for club and country. Top of the Champions League table after two games, Dortmund face Real Madrid on Tuesday, the side who beat them 2-0 in last season's final. "It wasn't easy.

In the first half we had a bit of luck, but we had chances of our own and could have scored more. We're happy and also relieved," Dortmund midfielder Julian Brandt told DAZN. "The goal we conceded was an absolute dream goal.

The lads did well. I don't think we can complain today." Dortmund coach Nuri Sahin cut a frustrated figure despite the victory.

"If we want to be a top, top team, we need to deliver every three days...

we need to defend better," he said. "We should've scored another in the second half and we were punished with a brutal goal, but then we got ourselves ahead again. "What I liked is that the boys stayed calm, we didn't get hectic.

" St Pauli striker Johannes Eggestein lamented "luck wasn't on our side today." Dortmund came into the game unbeaten in their past .
