Zizou Bergs of Belgium enters the Aix en Provence quarter-finals as the 44th-ranked player, holding a 1–0 head-to-head advantage over Pierre-Auguste Herbert. The Belgian has shown mixed clay-court form, with recent wins over Marton Topo and Andrey Rublev offset by losses to Alex Zverev, Flavio Cobolli and Marin Cilic. Bergs will look to capitalize on his ranking advantage and previous success against his French opponent on the red clay surface.

Pierre-Auguste Herbert of France arrives at Aix en Provence ranked 225th, facing a significant gap against Belgium's Zizou Bergs in this round-of-16 clay-court encounter.

The Frenchman enters the match as an underdog despite playing in his home country, with Bergs holding the edge in both ranking and head-to-head record at 1–0.
