Manquillo Alarza/Moriñigo Gomez look like the more “pure” pair with clearer roles: one building points, the other finishing. Stellato/Sussarello project as the heavier-hitting, higher-volatility team that can run hot in fast indoor Belgian conditions. Slight edge to Manquillo/Moriñigo if they control the net and extend rallies; Stellato/Sussarello win if they speed it up early.
