Head-to-head data between Unión Santa Fe Res. and Sarmiento Res. is still being compiled for this fixture.

Tactically, the interesting duel is between how Unión Santa Fe Res. attempt to progress the ball against Sarmiento Res.'s mid-block.

No.8 position — dropping deeper to receive between opposition lines rather than running beyond them, and by doing so pulling one of Sarmiento Res.'s central midfielders forward to open the pocket behind.
