#2 Lack of creativity while going forward
Yes, they scored two wonderful goals. Yes, they've been flying out of the blocks and slotting in chances with aplomb in recent weeks - something you'd expect from a team with such calibre at its disposal.
But, Dortmund certainly didn't create enough, especially in comparison to the hosts' approach. Dortmund were staid, unadventurous and flat-footed while going forward.
The clear-cut opportunities seldom arrived, perhaps due to the lack of movement from the wingers and number 10. Mario Gotze, although not on the score sheet, put in an all-round shift as he tried to link up play, free up spaces for the others and constantly spin off the back of defenders.
However, the likes of Hazard, Julian Brandt and Reus were far from convincing. Was it the cramming of wider spaces from Freiburg that restricted Dortmund, or was it the fact that everyone in the side was fatigued after the long journey to Prague in midweek - we don't know.
What we do know is that BVB and more so, Favre, need to rotate the forward players more often and license them with leeway to go out and express themselves.
