#2 Form of key first-team players
Almost all of Bayern's key first-team players are in full flow prior to the encounter. While players like Robert Lewandowski, Mats Hummels, Joshua Kimmich have all managed to sustain their good form consistently this season, newcomers Sebastian Rudy, James Rodriguez and Niklas Sule have also embraced their new challenges this season.
James Rodriguez, in particular, is in great form, of late along with Niklas Sule, who has been consistently challenging Jerome Boateng for a berth in the starting lineup. Even Arturo Vidal has shown great commitment over the past few matches and will be a key figure in midfield this midweek.
The seemingly impressive form of key first-team regulars might prove to be the real difference between the two sides as Dortmund brace themselves for a mammoth task this week.
