The lineups are in and kickoff is fast approaching at Signal Iduna. Here's a look at the team sheets for both teams, courtesy of Mainz 05:
It's an attack-heavy formation for BVB, with no Weigl or Gundogan in the starting XI. Gonzalo Castro, Shinji Kagawa, and Nuri Sahin take their places in what's sure to be a forward-thinking midfield. Another absence of note is Christian Pulisic, who did not feature in either the U-19 squad or the senior squad this week. Mainz is no slouch, however, and have firmly entrenched themselves in the European positions on the table. They'll be sure to have a few tricks up their sleeve as well. All aboard for kickoff!
