#2 Dortmund were once again undone by defensive issues
Scoring goals has not been a problem for Dortmund this term; indeed, they have scored 29 times in 12 Bundesliga matches (only Bayern Munich have been more prolific, striking on 30 occasions) and have found the net in all five of their Champions League clashes in a tough group.
The problem, though, has been their goals record at the other end, with 16 conceded in the Bundesliga and 10 in Europe. Tellingly, Bosz's men have only kept one clean sheet in their last 12 matches in all competitions.
They were shaky again here, although frustratingly for their Dutch manager, individual errors were more of an issue than structural weakness. Having said that, Spurs did take advantage of the gaps that appeared in the second half, but Dortmund's players did themselves no favours against an excellent side.
