Cristian Erbes remains an injury doubt for Atletico Tucuman after he missed the defeat to Central Cordoba last time out. Ramiro Carrera played up top last game, but he will no doubt return to his natural home on the wing as it was a failed experiment. Eduardo Salvio and Ezequiel Almiron remain absent for Boca following the victory away at Rosario Central. A formation change found rewards when they were needed but reverting back to 4-3-3 against a rigid Tucuman side makes more sense.
