Expect both sides to line up in a 4-2-3-1, and that's where this gets interesting. Gimnasia's predicted lineup from the recent Aldosivi clash shows a double pivot of Mateo Seoane and Ignacio Miramón, with Alexis Steimbach and Ignacio Fernandez providing width and Agustin Auzmendi leading the line. They'll sit in a mid-block, let Talleres have the ball in non-threatening areas, and then spring through the half-space runners. At home, they'll be braver than that — a bit more front-foot, pressing in waves, trying to force errors high up the pitch.

Talleres, meanwhile, will try to dominate possession. Their 4-2-3-1 is built around controlling the tempo, with the full-backs pushing high and the number ten drifting into the pockets. But that leaves space in behind, and Gimnasia's wide men will look to exploit it. The key battle will be in the middle of the park: if Talleres' double pivot can't get on the ball and turn, they'll be forced into hopeful crosses. If Gimnasia's midfield can snap into tackles and win second balls, they'll turn this into a scrappy, stop-start affair — exactly what they want.
