That's Dortmund though. The 2nd biggest club in Germany.
Werder Bremen are newly promoted back to the Bundesliga. It's like Bournemouth or Fulham buying him
That's a bit of a weird comparison. Last season was only their second season out of the top division ever, they've won three major trophies this century and have won a European trophy. They're not a small club. A more accurate comparison might be to Villa straight after they got back into the Premier League. If you want to compare Bournemouth to a German team, then think Hoffenheim if they had a ground half the size and were worse on the field
