Borussia Dortmund thrashed Legia Warsaw 6-0 in the Polish capital with goals from Mario Gotze, Sokratis Papastathopoulos, Marc Bartra, Raphael Guerreiro, Gonzalo Castro and Pierre-Emerick Aubameyang.
In the process they equalled the record for the most different goalscorers in single Champions League match, which has previously been managed by Paris St-Germain, Juventus and Bayern Munich.
Coach Thomas Tuchel was unsurprisingly happy with his Champions League debut.
“Even if it looked easy, there was a lot of our work behind it,” he said.
“Were Dortmund so good or Legia so weak? I don’t want to be philosophical here and judge it in this way. We were just the better team today, we had more scoring opportunities than Legia. Winning 6-0 means we put a lot of work in and I hope we will continue to work in this way.”
Meanwhile, Juventus could only manage a 0-0 draw at home to Europa League winners Sevilla.
£75m striker Gonzalo Higuain headed against the crossbar with Juve’s best chance.
“I’m disappointed we had to settle for a scoreless draw because everyone was expecting us to win three or four-nil,” said Juventus coach Massimiliano Allegri.
“We have five other games in which to secure our passage to the next round, but this game is a reminder that in this competition you have to keep your feet on the ground.”
