A Gareth Bale cross from the left of Werder Bremen's penalty area was put into the Werder net by defender Petri Pasanen, giving visiting Spurs an early 1-0 lead on their hosts.
Bale scuffed a left-footed attempt across the six, with a lunging Pasanen ebating Tim Wiese for the own goal.
The day's seven other matches remain scoreless.
