Galan/Chingotto enter as the more stable, higher-ceiling pair: Galan’s right-side power and transition game plus Chingotto’s defensive volume typically outlast more streaky duos over three sets. Nieto/Sanz can compete if they win the center early and keep rallies messy, but Bordeaux’s P2 conditions tend to reward clean net dominance and first-volley quality. Prediction: Galan/Chingotto in two tight sets or three if Nieto/Sanz start fast.
