1. FC HeidenheimvsFSV Mainz 05

Mainz 05 are historically a stronger Bundesliga side with greater squad depth and experience compared to Heidenheim, who have been battling to establish themselves in the top flight. Without recent H2H data, the pick leans on Mainz's general quality and away record against newly promoted or lower-mid-table sides. Heidenheim's Voith-Arena can be a difficult venue, keeping this prediction at moderate confidence.
