Sharifova/Collombon look like the more structured pairing for a Major: expect Collombon to anchor the left with higher-tempo volley patterns while Sharifova adds depth and stability in transitions. Peralta Exposito/Ferreyra can threaten with heavier bandejas and counterpunching, but they’ll need long rallies and disciplined lobs to stop Collombon taking the net. In Italy Major conditions, the edge is Sharifova/Collombon in two tight sets if they control the middle early.
