The Blues will be hopeful of putting their domestic form aside and coming away from Germany with a positive result to bring back to Stamford Bridge.
After topping a group containint AC Milan, Dinamo Zagreb and RB Salzburg, the Blues will be hopeful of making a deep run in Europe.

Dortmund, on the other hand, are in fine form in the Bundesliga and are challenging at the top of the table once again.
They will be hoping to come away from a 81,000 capacity Signal Iduna Park with a victory ahead of the clash.
“He is an impressive personality and a fantastic coach,” he admitted. “We are in regular contact and look forward to seeing each other again.
“So you don’t know how they will play. In defence they played with four but before also with three in the back. We will prepare for everything.”
Chelsea have now confirmed their travelling squad as they board the plane to Dortmund on Tuesday.
Kalidou Koulibaly, Mateo Kovacic, Wesley Fofana and Denis Zakaria have all recovered from injury to travel also.
