Bremen's players, meanwhile, felt they could have no complaints with the result after being thoroughly outplayed by Jürgen Klopp's team at the Weser-Stadion. bundesliga.com rounds-up the thoughts of the main protagonists from Saturday's highest-scoring encounter...
Borussia DortmundManuel Friedrich: I wanted to give the club something back. I was signed up late last year pretty much as a stopgap and just wanted to help out from the start in any way possible. But then I had one or two below-par games and being a fairly self-critical kind of person, I was extremely disappointed. Hopefully I've been able to repay some of the faith that's been placed in me.
Nuri Sahin: That was a really enjoyable game and when we're enjoying ourselves, these kind of results can be the outcome. Winning so convincingly is extremely important for us, we've finally managed a clear-cut success on the back of a dominant performance. That's good for our self-confidence, especially with such a busy few weeks coming up.
SV Werder Bremen
Nils Petersen: It was a fully deserved win for Dortmund. It's no excuse that we were playing against a very strong opponent today. We put in plenty of effort, but we made too many individual errors. We've missed the chance to get a few bonus points today, but this was a different defeat compared to the one in Augsburg - we can look at ourselves in the mirror and say 'we gave absolutely everything'.
Ludovic Obraniak: I imagined my debut for the club to go a little differently. I'm very disappointed. We were playing against one of the best teams in Europe, but they were better in every department: they played better than us, and they were also better physically and tactically. We have to work hard in training next week as three points against Gladbach are vital.
