Borussia Dortmund have reason to feel positive, for the omens could be on their side.
For the past has shown when they win in England, it proves to be a successful year for them in Europe.

Dortmund head to Old Trafford for the Champions League semi-final second leg, where they are protecting a valuable 1-0 home advantage. A memorable backs to the wall performance sees the German side grind out a dogged win, frustrating an Eric Cantona inspired United side.

This season may end up being their best chance to win the trophy, with Robert Lewandowski all but confirmed to leave at the end of the season.
What price him riding off into the sunset with a winner's medal around his neck?
