Giovanni Reyna netted his first Bundesliga goal to help Borussia Dortmund to a 3-0 win over Borussia Monchengladbach, with a limited number of fans gracing the German top-flight on the first Sunday (AEST) of the new season.
American Reyna slammed home like a veteran after being set up by fellow 17-year-old Jude Bellingham as an ever youthful Dortmund began the season with their usual promise.
Erling Haaland, 20, added a penalty and then completed a wonderful team goal after being played through by Jadon Sancho.
"It was a seemingly even game, Gladbach did well tactically in the first half," match captain Mats Hummels told Sky after an 11th straight Dortmund win over Gladbach.
"Second half it wasn't that we were so much better. With the quality we have...we can create chances and get goals."
Promoted VfB Stuttgart suffered a disappointing return to the Bundesliga when they lost 3-2 at home to Freiburg.
Fellow newcomers Arminia Bielefeld drew 1-1 at Eintracht Frankfurt while Werder Bremen, who narrowly avoided relegation last season, reverted to type and lost 4-1 at home to Hertha Berlin.
Augsburg won 3-1 at Union Berlin and Hoffenheim beat Cologne 3-2 late on with Andrej Kramaric hitting a hat-trick.
