Karim Adeyemi netted a hat-trick, Serhou Guirassy grabbed two goals and Emre Can and Felix Nmecha were on the scoresheet as the hosts ran riot, with Daizen Maeda’s early goal the only bright spot for Celtic on a sobering night. Celtic took to the pitch with a perfect record this season, their winning run including a 5-1 victory over Slovan Bratislava in their Champions League opener. Dortmund had found goals easy to come by and had defeated Club Brugge 3-0 on matchday one as they looked to build on last season’s run to the final of the elite competition.

Almost straight from kick-off Dortmund had a scare when Emre Can stretched for the ball and looked to have suffered an ankle injury. He soon returned to his feet and was ready to play his part in an explosive start to the game. Just six minutes in, Jamie Gittens got the benefit of a ricochet and raced in on goal, only for Kasper Schmeichel to race out and upend the winger without getting anything on the ball.

Referee Jose Sanchez pointed to the spot and Can stepped up to give the hosts an early lead. Celtic responded almost immediately. Arne Engels took possession and carried the ball on the right before swinging in a cross that Can failed to deal with, allowing Maeda to dart in and bundle the ball into the net.

Two minutes later Dortmund were ahead once more. Adeyemi used his pace to get free from his marker and let fly with a shot that deflected off Auston Trusty and past Schmeichel. After a breathless start, the action.
