PROBABLE LINE-UPS
Velez Sarsfield (4-5-1):
Marcelo Barovero; Fabián Cubero, Sebastián DomÃnguez, Fernando Ortiz, Emiliano Papa; Augusto Fernández, Franco Razzotti, VÃctor Zapata, Ricardo Alvarez, Maxi Moralez; Juan Manuel MartÃnez
Santiago Silva's continued absence means that Velez will line up with Martinez as a solitary striker, in an otherwise full-strength Fortin line-up.
Libertad (4-4-2):
TobÃas Vargas; Carlos Bonet, Pedro Portocarrero, Ignacio Canuto, Miguel Samudio; Sergio Aquino, VÃctor Cáceres, VÃctor Ayala, Rodolfo Gamarra; Manuel Maciel, Nicolás Pavlovich.
Ganso suffered a thigh injury at the weekend and is the big absence for Santos; Rodrigo Possebon enters for the 21-year-old as the Peixe are otherwise at full-strength.
Prediction
Velez Sarsfield 2-0 Libertad
