Erling Haaland scored a hat trick as Borussia Dortmund began their German Cup title defence with a 3-0 win over third-division Wehen Wiesbaden on Saturday.
The holders attacked from the off and went close through American forward Gio Reyna, but had to wait until the 27th minute for captain Marco Reus to set up Haaland for his first.
The Norwegian striker dusted himself off after he was fouled by the goalkeeper to score Dortmund's second goal from the penalty spot in the 31st minute.
He completed his hat-trick early in the second half.
Dortmund were without Julian Brandt and Thomas Meunier due to positive Covid tests, while Mats Hummels, Raphael Guerreiro and Emre Can were not deemed fit enough to play.
It was Dortmund's first competitive game with Marco Rose as coach and without Jadon Sancho, who joined Manchester United in the offseason.
Goalkeeper Gregor Kobel made his first start.
