Hansi Flick revealed his love of puzzles in the build-up to this reunion but in the end he was one move away from solving this one.
Many could not wait for the second instalment of this match-up, hopeful it would go one better than last week's five-goal thriller in Munich. Nobody was disappointed with the chaotic sequel that was served up.
For Flick he saw it as a test of his problem solving skills to see the Champions League holders go against history in overturning a 3-2 deficit. It was improbable, rather than impossible, history said.
They needed two but returned home with one.
